hfs-03mm & mx3 ?
 

Recently got a mx3 in a trade and it came with this rx and a novak xxl with performance devices xtals. Put the hitec rx in my car and it twitches like mad, the esc light even blinks off and on and it stutters and the servo chatters crazy to, so stuck the xxl in with same xtals and not a issue. So is this rx not compatible with my mx3? It is also a single conversion if that matters. THanks

Use an Airtronics single conversion crystal in the receiver and it should work providing it is a good receiver in the first place that he traded you. :tire:
