I'm having a 1990's model1/4 scale 7.5LB Great Planes Spacewalker re-monokoated and haven't decided on what would be a good 2 stroker for it, I used to be fond of Super tigre engines until I bought my first OS engine 1.20AX needless to say the engine is awesome & easy to breakin...I'm trying to buy a good quality engine with decent power, but also one that is with in my budget, I've looked at OS 95AX, GMS 1.20,Super tigre G90's, and towerhobbies 75. 91fx. anyone ever have a spacewalker if so what size engine did you run on it?

Thanks,
