I am a returnee, my dad got me into it in the late 80's an into the mid 90's. Then a long 20yr long absence. I got back into it last year, dug out the old airplanes an dusted them off.
We were towards the end planking the on trying out a 3 wire system. I don't know anything about this 2.4 system... Are you using a radio and receiver with batteries and a servo?
