I'm almost completely done with mine. Just need to complete the radio and Robart retract installations. I stuck with the 3/32" balsa sheeting for my wings, but used contest grade balsa and a sheeting process that keeps the weight down. I planned to use Monokote for covering the airplane so I wasn't too worried about the weight. It still came out pretty light. As far as the horizontal stab install I followed the instructions and just made a template using the plans and measured and cut the opening very carefully. It still was some work to get it glued in place but I shimmed it to the the exact incidence that I needed and then CA'd to lock it in place. Once that was completed I mixed a dry batch of epoxy and microballons and worked it into the gaps and smoothed it all out to permanently lock the stab in place and it made for a very solid installation. The engine is an OS FX61 with a MAC tuned pipe. Here's a couple pictures of my bird...
