Forgot to mention, we worked with it for about 10 flights last night. It runs a little better, but still all the same troubles. I dead sticked one time.

In straight and level flight it surges. On the initial climb it pulls STRONG but cuts back and flattens at around 50ft altitude.

I'm going to get some CP 15% ASAP and try it too.

Far as I know it has the H9 "Super plug" in it now. I have a stock of OS #8's and will try that ASAP although I think it'll be the wrong way to go.
