I flew my new Raptor 30 ARF for the first time yesterday, however I'm having a major gravity fuel feed problem. The tank seemed high to me from the start, but I figured being an arf it'd be okay. NOT THE CASE! I fill the tank and by the time I'm ready to start the heli, fuel is pouring out of the carb. It runs great on a half tank, but I can't get it to do the whole thing. I installed a header tank, but it just feeds right through it giving me crappy starting, and a super rich mixture. Is this a common problem and whats the best fix?

Thanks
