Greets! I recently swapped a bunch of gear around between my two cars and revealed what I think is a receiver issue but would like to be sure before I replace it.

The issue is with my kid's brushless Rustler. This car worked fine with my Flysky TX/RX but when I installed his AE XP3D (w/Spektrum module) and Spectrum SR3000 it glitches badly on hard acceleration from stop. It'll launch then die, no servo control or anything, and then launch again, then die.

I did recalibrate the ESC to the AE/Spektrum radio and verified that all batteries were adequately charged.

Last night I briefly swapped in an old Traxxas AM setup I had and the issue was resolved, so it's definitely an RX/TX issue IMO.

I don't have a spare Spektrum RX or TX to swap out; can anyone suggest a crafty way to determine where the issue lies? I'll buy a new receiver if that's the issue but I don't want to spring for that and discover that it isn't...

TIA!
