.46 Thunder Tiger and 3D Airplane
I just got a Goldberg Extreme 330. I am running a TT 46 Pro w/mousse can pipe and a APC 12x4. It hovers just a bit past 1/2 throttle with strong (decent but not rocket like) pull out if needed.
The only changes I made were Dubro Nylon Profile gear, a AAA 720mah Nimh pack, and a mini servo on the throttle.
