RE: Not a good day at the field
Like some people usually say - if you can take all your planes back in one piece - its a good day. I had a crappy day last Sunday. I haven't flown in easily 3 - 4 weeks if not longer (possibly longer) due to either one of the following factors - work, not being at home or the weather. So last Saterday evening I put everything on charge - got up at 06:30 Sunday and saw the weather being nice, but a wind starting to come up. I decided what the hell, I'm going out - it's just been TOO long. Packed my things and off to the farm I went. My friend which flies with me wasn't at home and the gf decided to sleep late. So on my own I was, but not really bothering me. Got to the field, just a slight breeze blowing and I unpacked everything. Put the wings on, connected everything, fueled up, tested the battery and fired up the engine. I decided since it hasn't run in quite a while I'll just tune it again. Did that and for the love of what ever name you want to use, I couldn't get it started again. So I waited a couple of minutes and tried again. Got it started and tuned it a bit more. Switched off, and by now the wind started to pick up quite a bit. Checked the wind direction and it was a complete crosswind over the runway. Our grassrunway, which would have been the runway into the wind, has not been cut since we haven't flown in quite a while, so it was so so so tall that there was no way you could use it. I decided to refuel, check everything again and see what the wind does. The wind changed more favourable for me and I decided to start up ... it wouldn't start - by this time I was swearing at this engine. I decided to wait a bit more. Atlast I got it started and by now the wind was on it's old course again. But what the heck I decided - I haven't come all this way for nothing. So I took off - quite easily in the crosswind I must say - and flew a couple of minutes. The wind was blowing stronger, but I had a great time. Came in for the landing - handled the crosswind much better than I thought I would. I decided to go up for atleast a second flight. Checked the battery and it was almost at low when loaded...what on earth!!! It couldn't be - we get usually minimum easily 4 flights out of that battery. I think it is my tester which is broken again, giving incorrect readings, since this happened a while ago. But I wasn't taking that chance and packed up and left. What is the lifetime of a rx battery usually? Mine is almost a year old now.

RE: Prop Safety, NEVER let your guard down. Warning: Bloody picture
Sorry to hear about the accident Ken. Hope it heals quickly. Having a look and reading through this thread it made me realise once again just how quickly something like that happens and how wrong we are doing it when me and my friend goes and flies one their farm. We don't restrain the planes. We simply hold the plane down with one hand and swing the prop with the other. We have never had an incident but it also doesn't mean it will never happen. I always used Evo props until I put an APC on about 2 months ago. Damn is that thing sharp. I cut my hand open just with priming the engine. When closing the carb with my finger - a part of my finger gets in the way of the prop. I have recently got a position to hold my hand without the prop 'slicing' me. I do have a very dangerous and very very bad habit...when I start up my engine, sometimes at turns the wrong way and as soon as I start playing with the throttle I move away from infront of the plane to get to my radio. By doing this I need to hold the plane on the wing which is on the radio side. It has happened a couple of times where the plane jumped forward when the engine starting swinging the right way - the plane then rotates on the wing which I'm holding and this has almost caused the prop to bite me.

RE: Carb leaking fuel
[quote]ORIGINAL: Seb23 Hey guys, i just finished up my engine stand, mounted the engine on it then went to go start it and i noticed when i primed the engine and then create compression i have fuel leaking from my carburator, specifically where the choke is. I have a Magnum RFS 70, i got it started but do not have the leak problem figured out. The engine is mounted up right if thats any help. What is my problem ? am i doing something wrong ? Is is normal ? Thanks [/quote] If you say fuel is coming out of the carb when you prime it...do you mean that after removing your finger from the carb when priming it is wet? If so, it is normal as far as I know. When priming you are "pumping" fuel into your intake for cold starting (well this is what I think it does and how I understand it[:D]) This will then result in fuel coming out of the carb.

It definitely sounds like a voltage drop. If you say the hinges wasn't very flexible...did the servo's centre properly? In other words, wasn't the servos perhaps still "working" even though you are not using it, trying to centre itself.

RE: Maybe a silly question: side thrust - why we need it ?
This weekend I found how much influence the side thrust actually has on a plane. After the rebuild on my firewall I took the plane out - pulled vertical and the plane yawed to the left and in flight it did the same if you looked carefully. I went home, added a washer at the back to give it more right thrust and WHALLA...you pull vertical and it goes and goes and goes straight up. I do however see my plane has a tendency to pull to the right on take off roll - but then it tracks straight as soon as it gains speed - this happened after the thrust mod. Oh well - it flies [:D]

RE: weight VS stability
I agree with your above post bkdavy, and no apologies are necessary - I was wrong and you corrected me - that's the way you learn. It's just out of my own experience which I commented on in regard to - I seem to be able to put a plane, which is more "nose heavy", down easier and faster (not refering to speed but to time and precision) than a plane, which is more "tail heavy". This could perhaps just be because of the way I make my approach and the way I fly - and having nothing to do with the CG (which I might have misunderstood it for). I thank you for correcting me and identifying information which I have miss interpreted.

RE: weight VS stability

RE: How do you Turn Off an Airbleed Engine
I usually set up my linkage by setting the trim setting to "neutral"/in the middle. Then I "open" my throttle on the Tx I then adjust the linkage so that the barrel is at full open. I then tighten it down and bring the throttle back - normally it is correct by this time. If it is not, I adjust it with the trim. You could also set your end points with it is still not right. I have seen someone kill an engine by pressing the applying pressure to the spinner - slowing down the engine. But this I will NOT advise to anyone [:D].

A plane which is more nose heavy will tend, apart from making it land faster, but will make it easier to get the plane down won't it? Where as a tail heavy plane floats and floats if you don't control your landing - then it stalls and falls. My edge has that tendency. You bring it in and if you are not concentrating on what you are doing - it will just float by on very low speed and sometimes stall (then you have to work quick and precise with your fingers) and then with almost no airspeed the plane will "drop" to the ground.

RE: 2stroke vs 4stroke
[quote]ORIGINAL: jimmyjames213 i dont have a 70 4 stroke. yes you can run a 4 stroke on 5% nitro, i have done it, it works ok. however your top end takes a hit as well as your idle. i run my .91 on 10% because i have plenty of 10% and dont want to go buy 15% and lug two jugs around. it works, the idle isnt as great compared to ys20/20 fuel. and i loose 500 rpm on the top end. however i dont care, i bought a bigger engine so i wouldnt have to worry about fuel. however most people here, and at my field, run 15+ nitro in 4 strokes. [/quote] Okay thank you. I know that my friend, who has this 70 Four Stroke, complains that the plane isn't very fast and I know the plane doesn't idle well. I think I'm going to recommend him to try out 15% fuel then. Perhaps this will solve the problem.

Yip I say go for it. I think you will do just fine. If you got the basics down then you will be able to fly without a real problem I think. Like was said just get help from someone in tuning the engine properly (whether on the forum or someplace else). You don't want to go dead sticking a plane the first flight up you don't know.

RE: Field Fuel Pump slipping
Buying a new one is a lot easier, but if you are like me who will first try to fix something... Just open up the cover - check that all the gears are still in place and not stripped. Mine gets a regular look at, I have found that filth clogs up in some areas and this not really causes slipping but more of strain - you struggle to turn it. In all honest opinion usually a manual fuel pump can fixed - well 80% of the time.

RE: error check
[quote]ORIGINAL: BarracudaHockey If you turn your transmitter on first, and then your receiver, the lights should come on steady. The only time they should flash is when you're binding (inserting the binding plug etc..) of if you turn the reciever off and on without turning off the transmitter. An example of that would be changing batteries without turing the transmitter off. [/quote] I don't have a Spektrum radio/receiver for my planes etc. Still using crystals. I do however have a Spektrum radio with my Blade CX2. When you switch on the transmitter you wait a couple of seconds then when you switch on the receiver/helicopter (which ever floats your boat) the light will flash slowly until it has connected to the transmitter or visa versa (don't know really which connects to which). If there is an error in the connection - for instance when you accidently have the throttle stick "open" - it will not connect to the Tx and it will continue flashing slowly. The LED turns solid as soon as it is ready to go. I do not know whether the Tx and Rx used in planes works the same so I apologise if I'm totally wrong here. The LED will flash rapidly when you are binding (bind plug inserted) - if I remember correctly.

RE: Opinions please
I can be way wrong here, but I thinka 46 is going to be too small if you want to 3D with it. Recommended perhaps, but not the maximum. I have a 61 2 stroke in my 46 size plane and wouldn't want to fly it with anything less. From what I've heard the Funtana is a good and nice plane - if you want to get into 3D.

RE: High and Low rates
I use my low / high rate setting only on a maiden. I dail in lower rates and also higher...I take off with low rates and if I feel it's too little input I switch over to high rates immediately. After the maiden or second flight I switch to high rates. Whether that be 100% rates or less. My Edge at the moment are set too 85% on high rates. This is my comfortable flying rates. It's not too twitchy and not too little. I will up it in a couple of more flights. I do however have set my "low rates" to 85% aswell, since I have found numerous times that I by accident knock the switch.

RE: On Rainy Days
A Simulator is an excellent way of keeping in practice. I used FS One and it was a great tool. Every evening I flew atleast for an hour. It helped a lot to keep my memory fresh and my reflexes (and doing the correct stick movements with the reflexes) quick. I flew a different kind of plane for 10 minutes in that hour. For example I would start of with a Mustang...fly that for a while...then fly a Corsair...then I'll fly with the Edge...etc etc you get the idea. I found that flying the different planes on the sim kept my mind sharp - because for instance the Corsair on the sim bounces easier than the Edge. Things like that. The great thing about the sim is you can adjust the wind etc. Like Minn said - it's not a substitute - but it is great for keeping yourself in good practise.

RE: E-poxy use for firewall
Okay so here is what I have so far. This week has been hectic so haven't really gotten to work a lot on the plane. I can't get the correct size dowel so that idea is out for me. The picture shows what I have done so far. I epoxied the 4 sides of the firewall (NOT shown on drawing) - fixing the firewall back into it's position. Then also epoxied the gaps/joints (as shown on drawing) I'm going to glue the triangle stock as shown aswell. The piece of plywood was installed after the previous crash which took out all the supports in the nose - the tank rests on this. The drawing may not be 100% correct but it's an idea of whats going on inside. Should this be sufficient?

RE: Dumb Question about Flutter
[quote]ORIGINAL: ser00 Thanks for everybody's replies. I do understand that gap has nothing really to do with flutter. My main question is what is the effect of flutter on Robert hinges as opposed to CA hinges. I did enjoy the detailed descriptions of the causes of flutter. Everybody here is correct. Gap has nothing really to do with flutter directly. I have seen some planes with huge gaps in them but do no flutter. They do not seem to respond very well or not as much as you think they should. As always, I appreciate the input. Happy flying and soft landings! [/quote] I think Ken has already answered your question there: "The use of CA hinges or Robart Hinge Points won't affect flutter in any way. You can still get flutter with either system."

Quick question on thrust angle - don't know why I suddenly don't seem to remember. Standing behind your plane (cockpit view) the engine should be slightly pointing towards the right or left? How many degrees is the thrust angle usually, probably differs - but what is a good starting point?
