I crashed my heli the other week when the tail let go and i managed to nose it straight down into the deck from about 15ft. Normal damage baldes,spindle shaft etc. Problem is the gryro really doesnt seem to hold so good now. Is it possible it was damaged in some way in the crash? It sits on my rappy directly behind the main mast. It now kicks the tail out when climbing out and seems to drift slightly all the time. Any thoughts?

Did you reset all the travel limits properly after the crash?

Did you set the gyro up PROPERLY in normal mode first so the heli hovers straight and true?

Did you get the mechanical adjustment correct in normal mode?

Is there any binding in the rudder mechanics?

Yep all set up was redone and in the same manner that had it flying sweet before. No binding or anything funny going on.

The tail seems to drift constantly even with the gain turned up full. It also kick out about 4 or 5 inched when u do a climb out or if you are doing any manouvers where the engine is quickly going to full throttle. It never did this before and if i had the gain turned up this high it hunted the tail about.

Which way is the heli drifting, turning right? Sounds to me like the gyro can't do its job properly, perhaps due to vibration or slop in the tail linkages.

LOL @ slow.

Ade
Same servo 9253 no binding on the linkage an everything seems to move freely. Its tail mounted on a quick uk mount with carbon push rod so its a straight push. When climbing out the tail kicks out to the right (nose goes left). Gyro pad has been replace using the futaba one still the same. And yes 100% sure i am in HH mode. The belt is relativley new and is not jumping i am running 85mm square tip sab tail blades (these worked fine b4). I take it is almost unheard of for one of these to be faulty after a crash?

I would have to disagree as it was fine on a futaba gyro pad b4. I shall try changing it to eliminate this though what do u recommend ade?

Yep i have a 9254 i shall stick this in and try it. Unfortunately the weather is crap here so will need to wait till it is nicer to go fly. I was just concerned that the gyro might be knackered

Right 9254 in it is the same I even put the push rod further out on the servo arm for more mechanical gain. Its a bit better but i still need the tx gain turned up full and the tail break away if doing backwards loops. I think my 401 is dead

Is that a Digi servo , dont you just set the gain to 0 or is it max , I set mine up and it says not to adjust any thing with a digi servo and it works very very well .

I was out yesterday in strong winds and its superb

I think that can be the vibration,may be because your tracking is out or some linkage.This is very popular with all gyros after a crash
