Hi,
I have a Sceadu Evo 50 that has been laid up for a while and since I have dusted it off it has a problem I don't recall it having before.
All is OK at moderate head speed but as soon as i clip up the revs with the first stunt curve it fishtails continuously. If I back off the gyro (CSM SL560) gain it helps but the tail feels less locked. I have checked all the boom stays etc are tight, tail servo is a JR8700, belt is ok, no apparent vibration, i even tried a smaller horn on the rudder servo but no better. I have a throttle Jockey on it so I can change the revs a little at a time and it doesn't take much of an increase to set it off.
Any Ideas?
Thanks in advance
Roger
