I have one of the prototypes of the Jetmach, very similar to yours, I've stripped it down and am recovering it now. I'm not sure you could use Robarts on the wings, you would need extra balsa blocks in the right positions to have something to drill into and hold them. I'm not sure about your wing, but I'm sure there is a minimum of wood on the hinge line.

One question, where did you get the brake for your nose gear? I've been looking for one of these, save me $200 bucks, just need something simple that works.

Thanks,

Luke
