Ok so did read that the kill switch can cause this so I went and removed this and plugged the battery right to the ign and it seems to be the same but now it fluctuates at low throttle not at mid or high now. I did also forget to mention that I do have a resistor on the transmitter. I also have a tach on the ign. and it is acting weird in that it keeps resetting and not always showing the rev's especially when I am starting the engine. not sure if this is related but another clue. Another annoying issue I am having is the only way to get the engine started is if I remove the plug and dump some gas in the engine. Otherwise is just does not seem to prime and get started. Not enjoying this engine so far but when it does run it sounds good, especially would sound good if I could adjust the mixture while it is running but I do not trust it to stay at any engine speed with the throttle jumping.

To CG I am kind of a beginner as I flew and crashed planes as a teenager that my Grandpa built. I have been flying small and medium foam airplanes now again for the last year and yes Glow is less complicated it is a lot more messy and I remember as a kid cleaning goo fom the side of myplane after every flight. So I built a big as plane and thought Gas would be easier. Huh...
