Finished! 14lbs 11oz with ZDZ 40, Bisson pitts, 9oz of batteries. Balanced at back of range with batteries just ahead of gear mount, but flies tail heavy in a 10mph breeze. Performance beyond unlimited even with questionable prop and burning about .5 oz a minute so I can easily cut 8oz off the CG by lowering the vent line in the tank. A floater - dead sticked first flight! Going to be a winner for us IMAC/pattern types.[
