RE: Skymaster F-15 construction
Yes, that's the airbrake kit from Skymaster. It doesn't get much easier, just take off your original hatch, cut out the hinge lines (already molded into the fuse) and drop in the new hatch with airbrake. The cylinder is an air-up, spring-down type so you only need to run one air line to the brake. I'll post more photos of that when I actually set it up.
