g-day

i have flown my brothers typhoon 2 3d and it does the exact same thing exept i dont crash it every 30 seconds i found that it is very tale heavy so i added blue tack in the cowling at the field until it didnt go verticle every time i hit the throttle i dont know where the cg is though try puting it on low rates but not to low you want to be able to get the plane back under controle if something happens. try flying with someone that knows the plane well.
good luck with the plane
