Have you tried it at home, but outside? (To isolate between temp and something at the field location)
Yup. No luck.
Have you tried detaching servos, one by one, at the radio? (To check for a servo issue)
Uh huh. The minute I plug in any one of the aileron or elevator servos at the field, I get flutter, even if it is the only servo plugged in, and even if I plug it into the rudder or throttle port.
Have you tried changing Rx antenna location, 90 degrees to long servo extensions?
Yup. I've even moved the receiver and batteries around and messed up the CG to try and get it to stop. No luck.
Does it matter how the Tx is positioned when the flutter occurs? ie, does pointing the antenna in a certain direction or moving to a different position change the flutter frequency or amplitude?
No. A buddy of mine and I were trying this the other day with no difference. I walked about 100 yards from the plane with my back turned and the antenna down on the Tx and it made no difference which way I pointed the Tx, the flutter persisted.
Have you twisted the servo extension wires? (I'll probably get grief over this, but I will never again use extensions without twisting them first - it will cause events similar to what you describe, it has happened to me)
You are the second person that has suggested this to me. When the other person suggested it, someone who was with me told me that it was an old wife's tale and that there was no validity to it -- someone whose opinion I respect.
I am now at the point where I don't know what to do anymore. I have pulled out some of the extensions and put shorter ones in this evening and I'm going down to the field in the morning to see if that makes a difference.
If it doesn't, I'll try the twisting thing. I'm at my wit's end at the moment and I'm now willing to try anything!!
Thanks and regards,
