My Ignition equip. is all mounted on the motor box. 2100 ni metal 6 volt battery. No RF at all. I'll check the plug. It did run correctly for a few minutes. Maybe it's starting to break in. I'll run some more fuel through it. I'm sure the jets are close. When it ran right it felt like it had good thrust. I have a Brison 3.2 in my 28% Wild Hare Unlimited vertical. I don't expect that from this bird but I would like reliability
