I've had a JR synthesized tx module for my 9303 for several months but never tried it until just this week. I used it a couple days ago with my raptor 50 and it seemed to do fine. Today I flew a tank and it seemed ok. Then the raptor 50 started twitching the pitch and throttle, and maybe some other channels, just a little but pretty fast.
After some head scratching and careful probing around the receiver, antenna and battery area and finding nothing, someone came over and plopped down an airplane engine on the table and the raptor glitched at that moment. Turns out the the transmitter, not the heli, is causing the glitches. Bang on the table the heli and tx are sitting on and the heli glitches. I put the old crystaled transmitter module back in the tx and the heli is glitch free when pounding the table. Swap the synthesized module back in the tx and the glitches return if there's any vibration on the tx.
Anyone ever seen this with the synthesized module ?
