Fuel - Byron fuel 15% nitro, 20 total oil

Thanks for all the posts; I’m still trying to get the needle valve situation figured out, if a damn plug would last! The plugs are “deformed” (don’t know if that’s the proper term) the filaments are either broken thru (this only happened once), or most of the time, the coils on the super plugs are pushed together or bent against the walls of the plug. I pulled the plug and borrowed a borescope from work, and there doesn’t look to be anything wrong inside the cylinder, no metal shavings, no rust, and no deformations to the head, piston or walls. As for the power panel, this has happened with my hot shot 2 rechargeable and I have an accu-glo Mk 2 that the heat for the plug is at half. I get a heat light, continuity is good, and it always starts and keeps running with a new plug. Only upon restart do I have issues getting it to fire. Now that being said, I have 15 landings on this thing, and only 2 were under power… I got real good at dead-sticking this thing real quick! It will run like a champ on the ground, but moving the throttles in the air has gotten to be a very dangerous proposition. It has not responded to throttle commands, cut it rpm’s by 4000 in level flight, or just randomly died! It gets frustrating for a new guy to get MABYE one flight, and then the engine gets me pissed off, and I don’t want to try and fly if I’m not in the right frame of mind, IM STILL LEARNING! Well, I’ll get off the soapbox for a while, but hopefully I answered a few of the questions some of you had, and thanks again for the inputs.
