RE: VSPEC FOR TRUGGY???
Yeah I guess it depends on what your needs are. Smaller tracks you want a ballsy low end engine whereas if you are on more open tracks you want a top end screamer. I have also found that most of the top engines are pretty similar in performance and in their stock specs, there's not a lot of difference appart from powerband characteristics. This is where engine mods come in to play. If you really want the edge over the comp, buy a Vspec and send it off for some engine modifications. This is really the only way to get maximum power from the engine. Yes it can be pricey but it will knock ya socks off I guarantee it!! I have an EB mods Novarossi that is thoroughly insane. Fastest top speed I have ever seen.

RE: SH PT2802B-P3 engine help catching up with its self?
Hey dude do you reckon you can rephrase that? "Catches up with itself" I do not understand what you mean. Whats it doing? Is it konking out on WOT but idles fine and it runs well when cold? Actually could be too lean on the HSN it sounds. Sounds like the LSN is dialled in but the HSN is not. Does it sound like its choking when WOT? Have you tried a new plug? In your opinion its running rich. What leads you to belive this? Is there lots of unburnt fuel being spat out the pipe?

RE: Break in method for long life? My idea (heat cycle) Please read.
Yeah when I say "The hotter the better" it goes without saying that is the case upto a certain point. For me 300F is about the limit I would suggest. If your engine "normally" operates much cooler than this and then all of a sudden it shoots up to 300F you know something is going wrong. Air leaks and a lean tune is the likely cuprit in that case. With your LSN, if the car idles down after 10 seconds its actually probably only a touch rich. I wouldn't lean the LSN out too much from that point. If you lean it too far you will find that your idle stays constant and does not idle down, you know thats the sign of a lean tune. It should idle down after about 20 seconds perhaps. It can be a very touchy needle and easy to throw your tune out so go easy on it.

RE: GO Tech .21 pinch gone after break in
Dont stress out too much dude. It may not need re-pinching. I have many engines that seem to have "lost" the pinch after runin but as its mentioned above it doesn't necessarily mean that compression is lost. It should still have a "pop" at TDC even if you can roll the flywheel with your fingers. Have you noticed any drop in performance? If you've blown it you would definately know the difference and you would have all sorts of tuning issues and running problems if that is the case. How tight was the pinch before the runin? Also when running it in try getting over 200F. I have found that 200F is really the minimum operating temps for most engines. Try to get the temp up as quick as you can when running in. This is why you should not run too rich but of course not too lean. Its a very fine line.

RE: Break in method for long life? My idea (heat cycle) Please read.
I know everyone is chiming in but most of what you have said I actually employ when running in my engines. I have run in a few now and there are some basics that everyone should be doing. Yes use a heat gun to get it as hot a possible. Start her up and then you need to get the engine upto 200F & above as soon as you can. You can really only do this by driving the vehicle around on the ground whilst the engine is under load. Do not idle it. Drive it around gently and with each tank, slowly lean it out to raise the temps and use more and more throttle range. You dont need to run it overlly rich as its already been said that you will have trouble getting it upto operating temperature. The otherthing I find very useful is try using a hotter plug than normal. This helps to burn the excess fuel as its running richer whilst running it in. I always stick with the same fuel from beginning as well. Also a thing about temperatures. Dont be too concerned about them. The hotter the better to a certian point. Some engines will run their best at 250F, some at 270F and I have had some like running 290-300F and as long as they are not tuned lean. ie there is enough fuel & hence oil getting to the engine, the engine should be ok. There is no "perfect" temperature as such. Every engine behaves differently. As soon as you realise this, tuning becomes way easier and you'll have more fun, less concern. After all these are meant to be fun!!

RE: After Run Engine oil question
Unbeknown to most, after run oil is pretty much mineral oil and thats it, so most machine mineral oils will work. However I have had great success with Pacer ARO but I have actually found that the quality of fuel has a lot to do with it. I use a very high quality Australian nitro from Massive Mods and if you use this gear, you simply do not have to use ARO period. Above all else whatever you do DO NOT USE WD40 as an ARO!!

RE: Axe Rossi Cobra X1 .21 Hot Mod 25% or 30% Byron Racer fuel ?
Its all a matter of preference really. I myself prefer to use 25% in all my engines as most of them are designed to be used for 25% before any shims are required. So for me 25% nitro is the best compromise. For me I don't see the point of adding extra combustable power in 30% nitro only for you to have to shim the engine to accomodate the increase. You addeth and then taketh away. Not a whole lot of sense me thinks. Anyway I would personally stick with the 25%. If you decide to switch to the 30% you'll need to add a shim or 2 to that Axe Cobra before makin the switch. You'll have to decide which way to go. Cheers

RE: "OFFICIAL"Redcat Racing 1/8th BUGGY thread (not truck thread)
Hey grizz yeah there's definately 2 schools of thought in regards to that run in method. I've tried it but always ran into problems when switching fuels. I've always been told to always stick with the same % fuel. Anyway I guess its a personal choice in the end. Yeah my truggy is in need of some fine tuning at this stage. It definately comes set up stock for very bumpy tracks and as such on grass its not so good. Problem is most of my running is on grass so I really need to thoroughly go over it and fine tune it. Suspension really needs some tweaking as its pretty spongy at the moment. Maybe perhaps its just the fact that I am not accustomed to it as I am with the buggy but I still prefer a buggy at this stage. Thats not to say my truggy aint any good. Its just no where near tuned as my buggy is for grass. I imagine this XT8 is quite spectacular when properly set up. Will take some time though. In regards to fuel %, there's nothing wrong with 11% oil content. Infact thats right about spot on in my opinion. As long as you run a touch rich when you run in it should be fine. I used to run fuel around 18% oil content and it was useless compared to the fuel I use now which runs an oil content of around 11-12%.

RE: "OFFICIAL"Redcat Racing 1/8th BUGGY thread (not truck thread)
fellas how are we? Hey grizz do you throw out your air filters when they become dirty? Wow I've never done that hey. I just wash them when they start to look dirty. First wash them in WD40 and then finish them off with dishwasher liquid. Gets them looking new again. Try it and save the cash for glow plugs for instance. Also just in regards to runins and fuel %'s; I really think its better if you pick an fuel % and stick with it right from the beginning. Thats my opinion anyway. I just think its unnecessary hey and infact using 2 different fuels is almost always going to cause a relative beginner more problems as the tuning becomes more complicated. Anyway like I said Its my humble opinion and I like to keep things simple and easy. No need to complicate the issue I reckon.

RE: "OFFICIAL"Redcat Racing 1/8th BUGGY thread (not truck thread)
TThib, as Grizz was saying, the clutch/spur gear mesh can be a little tricky to get right. Grizz couldn;t have explained it better; even with a good mesh the drive train is still rather noisy. But it still should roll freely if you push it along on its wheels. If its binding at all you'll feel resistance or it will feeling like its catching. As he says as well if you hold onto the spur and wiggle the clutch bell there should be about a 1mm of free play in the mesh. Chance3 if Jas's suggestion with the servo direction doesn;t work have you tried adjusting the idle screw down? Whilst the engine is not running, when you look down the carby throat the gap in the carby, when in neutral, should be about 1/16 of the throat diameter. In other words there should be just a slither of a gap. If the gap is too large your engine will idle too high. Conversely if its too small you will have trouble keeping the engine running. Anyway try adjusting the idle screw down(Anti clockwise) and see if this brings the idle down. Also before you start it make sure that the servo is closing the carby fully off. Also as Jas suggest it does make good practise to test the radio and servo function before starting the engine.

RE: "OFFICIAL"Redcat Racing 1/8th BUGGY thread (not truck thread)
Hey grizz yeah I've basically built the airframe of the heli and now I am waiting to purchase the rest of the gear. Ie all the electronics and she'll be good to go. Well crash no doubt lol. Lots too nice for me to fly hey. It will be a shame when I do scuff it up somewhat. It will be fun though. Jas is your buggy up 'n running yet? In regards to diff oils, I'd say 30K is too much for a buggy. Ok for a truggy but its a heavier drive train. I'd go for anywhere in between 7-10K in the center diff. Those 'superchargers' are massive overkill I think. All that's doing is forcing air down the carby so effectively it really leans the engine out. I dont think engines would last long using those hey IHO. Each to their own I suppose. Like its been said, they're super expensive so I think the money would be better spent in getting engine modifications. Much better value for money in my opinion.

RE: "OFFICIAL"Redcat Racing 1/8th BUGGY thread (not truck thread)
LOL glad everyone had a great xmas and Santa was good to all! lol Yeah well temp?...sheesh wow it got 44.5 today!! haha I think its Perth's hottest December day ever! Hows that hey? Mind you I have been indoors watching the cricket with the aircon cranked right up hey. Man my power bill is not going to look good! lol Oh well its worth it I reckon. Anyway I've had a good few days. Had a pretty cool Xmas nitro bash last Sunday. First time I've taken my truggy out with my Axe Rossi moddified LSK and given it a darn good thrashing. Its very interesting that I think I am the ONLY one to have a .21 sized engine in a truggy here amongst all the nitrobasher members. Suffice to say that its easily as fast ifnot faster than any of the others that run big block engines. I've always firmly believed that a top notch racing .21 will always out do a big block and from what I say on the weekend I think that was clearly proven. The great thing about the Xray XT8 is that its only a fraction heavier than a buggy so it only makes sense that its built for a .21 not a big block. I still think big blocks are best in the big trucks. You might think a truggy is a truck but its really just a fat buggy! lol Actually I was so supprised at how agile my truggy is. It seems to be basically as manouverable as my buggy hey. This is on grass mind you which has far more traction than soft sand. Whilst its great on grass, the stock setup is definately designed for soft, loose bumpy tracks. I think I would need to re-tune it somewhat for maximum performance on grass. Anyhow I was impressed with my moddified LSK. Its certianly got masses of power even running on a 15T CB. Gotta say the mugen CBs are asbolutely the ducks nuts for stock CBs. If you are looking for a new CB I'd highly recommend the mugen bells. The only thing that worries me at this stage is that the engine is running exceptionaly high temps. I had to richen it up majorly but it still runs very hot. Hmmm I'm kinda think there might be a leak somewhere in the carby. I have read that there has been issues with the axe carbys so I'm hoping its not that. Anyway I'll have to investigate that further I think. Also tried mix it up a bit different at the bash too. Took my walkera heli as well but that ended up being quite disasterous since it was windy and well, you know the drill; wind and little helis dont seem to mix! lol well not for me anyway. Anyway the fun didn;t end there because I took up a bunch of model rockets too! lol Wow these are an absolute hoot hey. Have you guys ever let off model rockets? Gotta say you have to try it hey cuz its a hell of a lot of fun letting them off and watching them to see if the parachute deploys! Sorry for the pun but it's a blast! lol sorry that was bad..hahaha Anyway lads enjoy the rest of the holidays!

A very Merry Xmas to all! Hey thunder tiger yeah mate its completely normal for engines to be real b**ches when running from brand new. Just hang in there. A starterbox will definately make life a lot easier getting it started and giving those knuckles a rest! gee been there, done that! Anyway mate as you run it the engine will get easier and easier to start so you gotta be patient. In regards to the fuel filter, yes I would say its absolutely essential to ensure longevity of your engine. You definately dont want to get any grit in the engine and you will find little bits do get into your fuel tank. Since you are new at all this are you aware of how to run in the engine from new? Have you oiled up the air filter? Also a very important thing to do. Most air filters do not come oiled and this needs to be done to also ensure no dirt gets down into the engine. Anyway engine it mate and if you have any questions just ask. Hey grizz yeah mate I may have bitten off more than I can chew with this heli but heck I am sick of piss farting around with my walkera. The more damage I do to it the less I feel like repairing because I really cant justify it hey. At least with a bigger, heavier and stronger heli it should theoretically be easier to fly and learn on. Anyway here's hoping! lol Cheers! Cheers

One of the things that takes me seriously ages to get used to is the spinning blades! Such a whoos I am they scare the bejesus out of me! lol With my walkera its a touch smaller than a t-rex but it took me soo long to get over the fright of the spinning blades but I did get used to it eventually. Actually I got a bit blaze' with it the otherday and let it the blades hit my trousers whilst they were powering down. Apart from the fact that it aint really a smart thing to do safety wise, I quickly found out how fragile the dam foam blades are! lol my god they seriously disintegrate way too easily. Anyway it so frustrating to learn on thats why I decided to get a bigger all CNC heli which can survive the punishment I seem to dish out. lol Anyway this is the one here: http://www.helidirect.com/product_info.php?cPath=29&products_id=3167

RE: Kyosho Inferno Us Sports
Yeah I'm using those MG995 servos and let me tell you; dont be fooled by their cheap price because so far in over a year they have far out performed 'famous' brand servos 10 times their price! Seriously they are top notch for the price. Having said that I got mine for aorund AUS$10 each which at that price I was prepared to use them as throw away items if they failed even after a few months. But No, 12 months on and they're going strong. They're actually rated at 15Kg not 13Kg as some are advertised so they make the perfect steering servo for any buggy or truggy. I would say be carefull if you plan to use them on the throttle/brakes. Since they are so strong you'll want to adust the servo throw otherwise you'll possibly rip out the carby slide. But they make for some serious braking power thats for sure. Sounds like you've got your steering sorted out. Supprised though that you want to desensitise the steering throw though. I am forever trying to get maximum steering and have mine very responsive at this stage but I guess I've spent a lot of time getting used to the control aspect. Expo on the throttle and brakes is worth playing around if you have that function as it will allow far better control in accelerating and braking. The spider diff is a diff made by Ofna/Hobao for the hyper 7 & 8s but as I mentioned, will fit the Kyosho Infernons as well. Basically a standard diff will have 4 internal planet gears, some have only 2, but spider diffs have 6 planet gears. Basically its just a much tougher diff and one that can offer a fair bit more traction control than a standard diff offers. But having said that, good quality standard diffs are just as effective and you dont really loose out on much compared to the spider diffs. I've also got a torsen center diff which is another completely diff again and offers the ultimate in traction control on particular surfaces. Anyway suffice to say that my mp7.5 probably has only a couple of original parts. I have hopped up pratically everything. Its fully loaded with fioroni ergal plates and braces and completes decked out in carbon fibre everything else. I'll post some pics if anyone is interested.

RE: nova P5XS idle.....
my 2c worth. Definately sounds like the LSN is too lean. Its such a fine line between a good tune and a bad tune its not out of the ordinary and most cases when your idle 'races' its 99% of the time, the LSN being too lean. One way to tell is whislt the engine is running, get it up to temp and run it around. Bring it in and give it some revs. If it doesn't idle down and effentually bog down its gonna be the LSN too lean. Of course this is if you have already check everything else and are satisfied that that the gap in the carby throat is where it should be. It should indeed, as you have mentioned, be a tiny slither of an openning.

Yeah like everything in this hobby EVERYONE has their opinion on the subject and we could all talk & argue about it till the cows come home right? LOL Personally though yeah I only really do it when the weather is cold. Since its winter in the Northern hemisphere its probably not a bad idea but it aint that necessary I think. I've run in quite a few Italian engines which are notorious for being as tight as a nun's bum but if you loosen the plug and add a few drops of ARO down the plug hole, that usually allows the engine to turn over. That and a strong torquey starterbox helps too. Actually some starterboxes are piss weak and not worth the time of day so it helps having a quality starter.

RE: Kyosho Inferno Us Sports
Hey fellas sorry to but in lol. Just poking my nose in. I am a long time MP7.5 owner so I thought I'd add my 2c worth. Yeah it goes without saying before adding any mods or hopups is to just take the buggy out and give it a good run and see how it handles. What you wanna add or hopup will largely depend on what surface you primarily run on. On grass, your settings will be farcely different to that on a bump loose track so you gotta take that into consideration. I will say that I would advise ANY new owner to clean out the diff oils or grease and add some quality silicone diff oils. Try a starting range of 5K front, 7K centre and 2K in the rear. You will be amazed at the increased handling just by doing this alone especially if the diffs have grease in them stock. My MP7.5 is an older version so I am not sure what they now put in the US sports edition. Take another step forward and clear out and add some quality silcone shock oils somewhere around 35Wt and again the handling characteristics will be startling. The next hopups I'd go for would be adding front and rear sway bars and front and rear torque bars if they dont have them already. Just these simple additions will go a long long way in improving the way the buggy handles. In regards to the engine I certianly would bother replacing that until you've learnt 'the ropes' so to speak and you've learnt a fair bit about engine tuning and maintenance. Also I must say any newbies reading this YOU MUST properly runin the engine. This is a must and if you're scratching your head wondering how to do this either ask away or do so searching as there is a lot of great information out there in regards to engine runins. For god sake dont got thrashing that new xmas toy BEFORE you do a proper runin. This will insure that your engine will last a longtime and you'll get maximum enjoyment from it. Also another thing from past experience with this buggy is that the GXR engine is notorious for running at very high temperatures. So dont be alarmed if your engine is running in the vicinity of 280F. It actually seems to be normal for these engines and they perform their best at these temps. Having said that though, it wont hurt to run it slightly rich and expecially so if the engine is new or relatively new. With the MP777 Chassis, no it is not compatable. Mounting holes are slightly different in a few areas so its of no use for the MP7.5. You can however get upgraded chassis so dont dispair. Alloy diff cups are nice but not necessarily an advantage. I've never had to use them but I suppose they couldn;t hurt. Depends on how hard you wanna push the buggy I suppose. If you are doing a lot of bashing & jumping it may help but having said that I have put my mp7.5 through a lot of punishment and never had any issues with the diffs. I'd definately look at other areas to upgrade before those. Also hyper 7 & 8 as well as mp777 diffs ALL fit the mp7.5. Actually I use hyper 8 diffs and they are very very nice. In regards to the radio and the steering throw, my original perfex radio did not have that function. All it has is dual rates and thats it. What you want to change is the exponential of the steering throw and correct me if I wrong but I am unaware that the stock radio has that function. Is the radio all digital with a digital screen? What other functions does it have? Normally those sort of functions are on more advanced after market radio systems. Again I could be wrong. I hope I'm not repeating stuff already said; I probably am so applogies if so. But otherwise, as always enjoy! bash hard or go home...

RE: Using a heat gun to break in..
actually a hairdryer is often safer. You gotta be soo very carefull with a heatgun as they're usually used for paint stripping, if your not careful you'll start melting the pastics around the engine if its on a setting far too hot! lol

RE: Has anyone heard anything about the redcat hurricane? good or bad I would liek to hear it.
All the naysayers, have you ACTUALLY owned owned one? Da Smak, for one, I'm looking your way. Of course you haven;t. Whilst certainly not the best out there for a beginners buggy they are tough as nails. Was my first nitro and its still going after over 2 years of serious abuse. Broken only a couple of parts in that time. The only thing that makes it a pain is parts are really hard to source other than the internet or Ebay. Its not like you can walk into a shop and buy parts off the shelf. In that regard I'd tend to point people in the direction of Hyper 7s as they're not a whole lot more expensive than the redcats, just have far better parts backup. In terms of quality though the hurricane is tough as nails and actually comes with a lot of things standard that other more reputable brands have as hopups. That said, it goes without saying that you get what you pay for. Its certainly no mugen or xray thats for sure but its not something to sneer at like the comments above. Just go check out Redcat's own forum and ask the hundreds of happy customers what they think themselves. The positves definately outnumber any negatives thats gotta be said. Sure, EVERY product range has one or 2 glitches that gets past quality assurance and sure if you've had bad luck, then just put it down to just that, bad luck but dont come on hear making sweeping generalisations that they all suck. Its simply not the case my friend. One reason you hear people having issues is the shear fact that because they are so cheap to buy, they attract mostly beginners and newbies that almost always have problems with a first time buggy. Its to be expected really but I think they corner the bottom end of the market where people can enjoy and enter into the hobby whereas with other brands the pricing is well out of reach of the common man. I certianly would not have got into this hobby without having learnt "the ropes" on a cheap platform that I wasn;t too affraid of stuffing up due to not knowing what I was doing. In that regard I think the redcat serves a great service to the industry.

takes a bit longer but a hairdryer does the trick if you are really desparate.
