RE: my plane is ballooning
I bought a Great Planes Escapade ARF as a second plane and love it. Plenty fast with just a .36, cheap, easy to build, easy to fly, nimble.
I have a Sig Kadet Jr which has had an OS25FP, Irvine 25 (wow, really powerful), and a Thunder Tiger GP25. It ballons too but it isnt terrible, probably has plenty of down thrust.
