Frank,

Ibet I could swap out the fixed gear for a pair of light mechanicals and a light servo and gain not more than 2 oz max. The legs on the Tusnami are pretty beefy as are the blocks. Hardened MK SS type gear is amazing and weighs very little. With your building technique I'm not sure but Isuspect that my foam wing would weigh less than my build up - especially if hollowed! We'll find out...

David.
