So , more than a few people have expressed concern over the amount of wing flex exhibited by the techpod . To exhibit just some of the strenght of the 9 mm OD 7 mm ID tubes I use I put together this quick clip .
that is 2 x 42 inch long 9mm tubes connected by a 6 inch x 7 mm inner connector rod , lifting a 5 gallon jug of water @ 42lbs suspended in the middle .good for a 8.4 g loading with a 5 lbs techpod and not all the lift comes from the tips unlike this demo . the spar could have taken much more. You may notice the two small nylon pieces in the middle . these keep the whole thing from exploding .
