Frank,

say, how much does your wing weigh as is (gear, wheels, everything)? Mine's got a boat load of covering (MK) and nothing is hollowed so Ibet it is heavier than yours. I'll weigh it tomorrow. I'll also weigh the retracts (again) and think about a light retract servo. it'll have to either be a mini proportional or a low profile retract (180 deg) servo. The wings are skinny!

David.
