You will not like my suggestions, but they are based on experience.
1. Replace lipos and regulator with a 5 cell NiCad or NiMh or 2SA123-2300 battery going JUST through the JR HD switches on the RX.
2. Replace the lipo and Jomar optical kill (bypass all that crap) with just a REGULAR 4 or 5 cell NiCad/NiMh or 2SA123
3. Don't change anything else.
4. Run the engine. Do everything you can to make it act up.
5. Observe that all problems are gone.
6. Beginning with the ignition stuff, replace ONE piece of your original stuff, one at a time, until the problem reappears.

(You will find the Jomar and the MPI regulators need to be put in the round bin)
Tried all that. Took the regulators out and put in a 6v nimh direct to the rx, no switches no regulator, still have it. Took the Jomar out and hooked up direct to the ignition with a nimh, still there. Horizons answer after the 2nd call was to put rf chokes on everything. I'm not above doing this, but I can't understand what changed after 2 gallons to be causing this, I understand that 2.4 can still be susceptible to electrical pulse, but it's not supposed to be taking hits from RF, and I really can't explain why it backfired on my this afternoon. A couple of the guys at the field are convinced its the igniton, but DL says it's not. I don't know anymore. The ignition is the ONLY piece of equipment that I haven't been able to isolate. I've got a qq 23% yak with the exact same setup, only differences are motor(evolution 26) and servos(jr 8411). Same batteries, regulators, switches, rx, etc. It's on it's 2nd season and never a glitch or problem. Got 6 1/2 gallons of fuel through that one.
