Since you stated all the control surfaces are ( fluttering ), can you tell us if the servos are moveing or is it just the control surfaces moveing? A low reciever battery voltage can cause the servos to act nervous. Also on 72Mhz, ( you didnt state 72 or 2.4) if you are doing all this with the antenna collapsed on the transmitter or rolled up on the reciever it can cause the servos to act this way. The only thing common to everything ( in the plane) is the reciever battery & switch. Check these for loose or corroded connections. Is there any way you can get help from someone at your local club?....Gene
