Hey guys yesterday I was tuning my OS 46AX when I discovered that the High Speed Needle bracket had broke off(previously damaged from a crash). The High Speed Needle was dangling but still secure enough for me to do some tuning and it didn't cause any problems. But today I was messing around with my Twist and all the surfaces responded to my inputs, but as soon as I fired the engine up and gave it some revs, nothing was responding to my inputs. Everything was twitching and wouldn't respond. My receiver battery and transmitter battery were fully charged. The antenna on the transmitter was bent 90 degrees like it should be, the only thing I could think was maybe there was noise coming off of the bracket since it was vibrating against the engine. So I killed the engine and everything worked fine, then I removed the bracket to see if I could eliminate the two metals from vibrating, but it still caused my controls to go haywire once the engine was running. My radio equipment is only about 2 weeks old and have never been in a crash. I didn't think 2.4 GHz technology was effected by stiff like this. The only other thing that was different from yesterday and today was that I didn't have my wing on the plane yesterday, but I removed the wing/disco'd the ailerons and it still had the interference. Im not sure what to make of all this. Also my throttle pushrod is a plastic pushrod, so there shouldn't be any noise coming off of that.
