Hey 3-d flyer, glad to hear you like the brison so much.
everyone tells me mine is overpowered with the brison until I take off and go straight up like a rocket. this is a great setup.
after flying mine for several months I finally put in a smoke system and droped the tank size from 24 to 16 OZ and I can still fly for twenty minutes on a tank.
I have been slowly moving the cg back and it just keeps getting better.
WLYDMAN
