ditrybird- It depends where you put your sensors. If you are at the top portion of the combustion chamber and on the (hottest point) back side against the cylinder, not the fin, I would say around 330. The front would be much lower.
Does eagle tree make a sensor for under the plug or just those wrap around ones??
I have the wrap around placed just above the exhaust. I don't know if eagle tree makes the under the plug type. That would be better.
So far I have not seen more than 200. I will move the sensors to the top the next time I fly it.
