I have been putting together an ARF Edge540T... when I went to do the electronics and started testing them I would get some wild/spastic past dual rates servo chatter... it would occur off and on when I would touch the rx battery pack... my tx battery was low so I charged it up.. seemed to fix it then tonight I got some of it again... Im building in my shop with many tools etc.. around some on the table very near where my tx and antenna tail was... moved it all and it seemed to fix..... could the low tx battery / lots of metal near tx & antenna have caused this?? Im using Futaba 7cap tx / 4.8 vlt bat. 1200mah
