I'm at 51 ozs including my mount and you're at 57 without yours. Put the servos in the tail. It'll balance great and you won't have to work out the geometry on the pull-pull system. It still uses two on a y-harness but 2 5645s will cost less then the one 5955 and give you more power. BTW I'm still learning 3D, the guy flying my plane in that video is the National Freestyle Champion and IMAC Unlimited Champion so don't think I'm anywhere near doing that. LOL[&o][&o][&o][&o]
