here is a pic of my balaning machine with a block in the front to give me enough clearance from the gear, i think it worked out, but i would welcome any advice on my technique.
I ended up moving the battery just behind the c/g it seem to work out, it's about 1/4 bubble nose down.

also is a pic of my "hanger" appreciate the stripe tip, i might just do that to hide the mounting holes on the top wing.....thanks
