[quote]ORIGINAL: ingleburn Hi guys, well I finally got around to maidening my Pro this afternoon.A lot of surprises but didnt crash so thats a bonus. Had a lot of expo on it and really noticed the difference compared to the GT. It was so docile it wasnt funny. Had a few problems, the main one being not enough pitch. Had to have the stick almost 3/4 up to even hover. When I got home and put a pitch guage on it I found that at centre stick it had -3.5 ° pitch. Dont know how that happened as Im usually so careful setting them up. Wound out the links about 2 turns and now its spot on and swash is level. Readjusted the settings to get 10° pitch and 8° on Ele and Ail so all set for another try tomorrow, weather being good. Apart from the pitch problem it seemed to be smooth and stable so I think Im going to like it. [/quote] Nice maiden. Looks like it' s going to be a nice heli. Yes you could hear that negative pitch when you are spooling up. I run +/-10deg and 6deg on my pro. Works well for me. Jonesy

[quote]ORIGINAL: Kozzy_98 Hey everyone! My flying streak with the #2 came to an end today! Was a typical beginner crash and had a blade strike, while landing a tad on the tail. Result = Stripped main gear, bent tail boom, bent flybar, busted main blades and thats about it. Main shaft hasn't bent, which is lucky. And as for the feathering shaft, I have absolutely no idea, but I don't think theres any damage to that either. Luckily, no damage to the fragile HXT900 cyclic servos as they are a pain to remove and install. My #1 helicopter is starting to frustrate me! Even with the gains down to the low 50s on a Spektrum radio, there is still a wag. I recall that someone said something about the tail servo and how far up the servo arm the ball link is attached to. Tail servo is a HK933MG servo, gyro is a HK401b. The beast helicopter is a frustrating build too. Upon realising that the belt was in the wrong direction, I flipped the belt and it was slipping everywhere. Changing the belt tension didn't help either. Upon realising the belt was dead, I decided to replace the belt. So I found a belt in the box that Phil gave to me. Silly me didn't check its length, and when I mounted the tail back on the tail boom, I realised that the belt was way to long, presumably for a 500 size heli. Oh well, my mistake! In my previous big order from HK, I placed an order for a Phoenix flight sim dongle. Suprise suprise, it WORKS! At least with phoenix v3.0p. Don't worry, I'm not going to give up! The satisfaction from flying one helicopter through 6 lipos in a row without crashing beats anything else!!! [/quote] Crashing is part of the learning curve unfortunately but it's good your not giving up....it's worth it. Re the #1 and wag. It sounds to me like you have one of the newer 401b's that they changed the chip on and they are way too sensitive. If that is the case you'll never get it to work. I would suggest you swap the 401b off the crashed heli and wack it on #1 and see what happens. At least you'll know if it's the gyro or the heli causing the problem. With regards to the ball on the servo arm, the further out youput it the more throw you will have on your tail slider. If you have the ball too close you might not get the full travel on your slider in each direction. From memory you want the ball about 7-10mm from the horn screw. Jonesy

RE: HK-450GT CCPM Alloy T-Rex compatible - Part III
Got the TGY-306G installed into the tail on my new Tarot 450 PRO V2 FBL build this morning. Servo looks solid. It's nice and fast and SUPER loud. Would have been nice if it came with a round wheel servo horn as well but a bit of trimming on the standard horn sorted that. I've got some wiring to tidy up and some final pitch settings to check and it's ready for a maiden hopefully on Sunday. If anyone is interested in the specs for this build it's got the following config: Tarot 450 PRO V2 FBL barebones kit from oomodel ZYX v1 (not running 3.5 firmware) Hitec HS-5065MG on cyclic TGY-306G on the tail Spektrum AR6115e rx Turnigy H2218 Motor with 13T pinion (This is the red motor with the silver can, 3550kv) Turnigy Plush 40amp ESC CF Blades Standard in the kit Nano-Tech 2200mah 3S 35-70c Really looking forward to flying this one. If it's a screamer i'll drop a 13t pinion into my other 450 PRO as well. My mcpx has been out of action for months and I have some parts arriving today to freshen it up. I think when they get to a point when they need major repairs and lots of parts replaced it's better just to buy a new one. Hope everyone gets some flying in this weekend. I'll be out of the Phoenix Fly In, unfortunately during the day on a weekend I'm too busy. Jonesy

[quote]ORIGINAL: ingleburn [quote]ORIGINAL: Kozzy_98 @Phil - Good to see you mate! Glad the planks are your more relaxed form of RC! Hopefully your maiden of your balsa plane goes well. I would assume that crashing one is not like foam in the way that foam is just CA/Hot glue it all back together again, rather balsa is crash, swear alot and buy a new one! Well, I have an annoying problem with my #1 450. When I take off, it wants to lean to the left and back at the same time. Even though I have my swash absolutely level and pitch is 0deg at mid stick. The swash also moves up and down the pitch range perfectly flat. Even so, it wants to move left and back. [/quote] Kozzy, having a dead level swash is not going to mean that your heli will fly level. To many variables that I dont understand myself. Brian and a few others only eyeball there swash for that reason and trim to suit. Ive always been pretty lucky with mine but best to use trim to make it level in a hover. Then if you want take notice of how much trim you have added then adjust the links by that much and reset trims to zero. You could also move your battery slightly forward as well which will move the C of G [/quote] +1 .... good advise. Back in the old days when I had a flybar ... ..... I used a few clicks of trim to get it right then take the trim out and adjust the swash links. Reason to always do this and zero trim is your radio (spektrum I presume) will not carry your trims between flight modes ie normal and idle up, you have to set the trims in both so there is margin for error...best to do it mechaniically. Also... you'll notice when you spool up your mcpx that the swash tilts automatically untill your about to lift off....ahhh...technology. Jonesy

I'm happy to say that today (depending on your location) is the one year anniversary of my first and maiden flight of a CP heli. My HK450GT with training wheels had it's first flight in my back yard. Wasn't ideal conditions and was a bit dangerous but after hearing the noise and hovering for more that a couple of seconds.... I was HOOKED! So thanks to all those that have helped me get to where I'm at today and hopefully I've been able to give back a little that I have learned along the way to help others. This was my maiden flight.

RE: HK-450GT CCPM Alloy T-Rex compatible - Part III
[quote]ORIGINAL: ingleburn [quote]ORIGINAL: Kozzy_98 Well, had another great day of flying. This #2 heli is my favourite, only because it flies properly! Over the course of 6 packs, I was flying side to side with some aggression, all while being in complete control! It was amazing to see how much I progressed in the 6 packs! However I will need to check my blade tracking so that it flies more efficiently. Also put about 4 clicks of left trim to correct the tail, but there is still some drift. I will see what I can do to fix this. On the Beast helicopter, I think I will need to replace the tail blade grips as one of the screws hardly holds one of the blades. On the #1 helicopter, even though I have a digital servo (HK 933MG) it seems to wag alot @ 62.5 gain, and also seemed to piro to the left. I am not sure how it flies, but when I saw this happening, I backed off the throttle. It also tilts diagonally to the right rear side, even though I have levelled my swash perfectly. Need to fix these problems before I crash the #2 helicopter. Flying side to side gave me some ideas on how to do some FF. Most importantly, it told me that once I am flying in a direction, the rudder will not affect it by itself. Instead it requires rudder + cyclic input. Also had a father and son who talked to me after I landed. Had a nice chat, and the father told me about how he had a coaxial but he couldn't get it trimmed, so instead he tried planes. He said that it wasn't as bad, but he gave up because he could fly it for a bit, then he would crash it. Generally when someone asks me questions, I aim to be as polite as possible. After all, they could work for the council and I don't want to give them the image that RC flyers are disrespectful! Otherwise I wouldn't have an oval to fly at locally. [/quote] Glad your having fun and getting a few flights in. Keep at it and it will get easier. Adding trim wont fix the drift you have as the gyro will just think the trim is an imput and will adjust it back again. More than likely your gain isnt high enough or there might be a vibration issue. What gyro are you using? Im always ready to have a chat with spectators, unless there the stupid ones that walk onto the field while Im flying. [/quote] I think he's using the hk401b and judging by that gain setting it's one of the older ones that actually worked. I did have one that worked on my very first heli, and it seems they all suffer from the left drift but it's fixable. Ingleburn is dead right about the trim. You don't want any trim or subtrim with these gyros. Take it all out of your tx. Make sure you have the gyro powered up for a little while before you try and make any adjustments as well as they suffer from temperature fluctuations. You need to dial out that drift in rate mode. Adjust your linkage (or slide the servo on the boom) to add some pitch untill the tail holds and does not drift. Switch to HH mode and it should be locked in much better. Jonesy

RE: HK-450GT CCPM Alloy T-Rex compatible - Part III
[quote]ORIGINAL: Kozzy_98 Hey guys, having a bit of a problem as far as my MT kit goes... Just spooled up the motor to check if it was spinning in the right direction, and something didn't sound right. It sounded as if something was restricting the movement of the motor and the motor RPMs were going up, then down even though my stick was in the same position. So I checked the belt tension, all good. Meshing between the pinion and main gear was good. However I am not sure about the meshing of the tail drive gear and tail belt gear. This seems to be the problem because when I spin the head in the opposite direction, it is not smooth unlike both of my GT frames. A tad frustrating, but oh well... [/quote] I'll throw a few suggestions...something may help. - Watch out for soft start on ESC...this can be a little confusting if your giving throttle and nothings happening then it revs up. - Take your main gear off and spool the motor to check to see if it's free and working as per normal. - Check you have not overtigtened the main gear bolt as this will warp your tail drive gear (autorotation gear) and it will have a tight spot with your tail belt gear. You may just have a warped gear which is highly likely. Sounds like the problem is the mesh between the autorotation gear and the tail drive gear. These gears tend to be warped and will wobble a bit but still maintain good contact with the tail gear. It's when it's warped the othe way (ie oval instead of round) that you get a tight spot. Hope that helps Jonesy

Been a bit quiet in here and your blather will be welcome. @ all. Went out again this morning and found a bigger patch of ground to fly on. Weather was great and really enjoyed it. Vids uploading now but no blather as I was kinda expecting a crash as Im going a bit beyond my comfort zone. Sorry to report no crashes but on the last flight it glitched again so Ill upload it for you to take a look at. Seems to be the same symtoms as Simons, flying into the wind and giving elevator it just takes off. Luckily Im only trying to level out not do a loop as Simon is when it glitches. [/quote] I'm not happy at all with 3.5, it's not flyable in anything more than a slight breeze. It's interesting if you fly in dead calm conditions you never see this problem, yet if you fly into a headwind more than about 5 knots you get cyclic pitch issues. I think I'm going to flash the old firmware back. I was reluctant to update to this 3.5 but over on rcg people are raving about the improvements and most people have had success so I bit the bullet. I havn't seen any discussion on the pitching issue. I'll be leaving my v1 zyx in the new 450 pro build at the current firmware. Jonesy

[quote]ORIGINAL: mnemennth [quote]ORIGINAL: ahamay [quote]ORIGINAL: Kozzy_98 The tail servo will be that new TGY-306G servo from HK which looks to be an ablsolute ripper. What I have found with the new build is that the MT frame, the one where you need those servo mounting parts absolutely loves the HK939/929MG as the cyclic servos when the mod is performed on them. This works well

RE: HK-450GT CCPM Alloy T-Rex compatible - Part III
I've done another 5 flights on mine this morning with the 3.5 firmware and it's flying ok... I've tweaked quite a few settings and the pitching problem has not reappeared but it was dead calm today and I only seem to get it when flying into a head wind. It's like the gyro is correcting the wrong way and it's pitching with the wind instead of against it. I don't know but I hope there is another update soon.

This works well for me as I have alot of 939/929MG servos and like 3 spare MT frames! [/quote] HK have just added a High Voltage version of that servo as well...something to watch out for..... there's two version to pick from now. TGY-306G-HV High Voltage Ultra Fast/High Torque MG Digital Alloy Cased Servo 3.7kg / .05sec / 21g
