Ooh... ohh... THEY'RE WINGS!!! Our team is doing something like that, but too much stress on the motors... soooooo we used pneumatics... if you already have a system they're less weight...
Guess what? our frame is 48 pounds driveable... it's made out of reduntant extruded aluminum, and supported a grand total of.... 600 POOOUUUUNNDDDSSSSS!!!! (4 team members) I liiiiiiiike. yes yes.... plated with lexan, it should be niiiiice. I like lots.
ah well, what have you.... good luck with your blocks of wings, I'm glad mine has more finess. and they doooo support 'bouts 200 pounds apiece... haw haw haw... for a third year team we're not doin' too badly.
hope our treads don't rip, though... (eep!)
Good luck to ya'!
