I finished mine a couple of weeks ago. It's turned cold now here in Michigan, and looks like the maiden flights won't be until Spring... Details: Brison 4.8 twin, Hitec digital servos (5645 + 5925's), Airtronics Stylus PCM, ElectroDynamics Pow'R Bus Pro, 4 cell Nicad on ignition, 4 cell NiMH on receiver/throttle/choke, 5 cell HiMH on balance, Ultracote and PPG paint. Total weight 24 lbs.

Regarding the wrong size holes for the stab tube, I called GP about this when I received my kit. They sent me updated parts that were better. No, I don't think there's a reason or purpose, just a mistake.

Mine is pretty much stock. I made two changes. I added Dave Brown CF on the wing spars (on the outside, between the spar and the sheeting). This is left over from my glider days. Adds a tremendous amount of strength to the wings. I don't fly too aggressively, but I do think this will reduce any chance of the wings folding like some have. I also totally changed the canopy construction. I built a frame from pretty hard balsa, and left it open. This was lighter than the stock method, gave me some "meat" to put screws in around the sides for the canopy, a place to mount a block to hold in place with screws from the outside, plus I think it looks pretty cool. Some of the higher end giant scales do something similar to this, at least that's what I saw at Toledo. Here's a couple of pictures. The first two were before painting, the last one after.
