90% this is RX antenna short circuit. The core lead might touch upon the shield. Solution: I changed the co-axial wire on my RTR and the problem was solved. It requires vy accurate soldering and should be done by a mini soldering iron not to overheat the scheme contours...

My question, what surface radio out of G3 i.e Airtronics(Sunwa), Futaba and KoPo... can be converted for the left-hand driver? Thanks....
