Richard,
I'm treating my Score as strictly a test bed for my Saito 56 before I spend all winter building a ship for the Saito. If I were serious about it, I'd at least run a strip of 1/4 inch stripping tape found at the hobby stores, around the perimeter to seal the canopy. Seeing it only screws on, if it gets gunked up, just removed it and clean it up. I glued on the stab, but left the wing only screwed on. I replaced the bellcrank, and control horns, and used ball links and carbon fiber pushrods. I used the motor mounts to mount the Saito and it looks like it'll balance right at the suggested CG of @4 inches aft of the LE. Weight is @ 65 ounces. I did mount a CF LG to the fuselage just in front of the wing though. I added 3/8 sq hard maple to each side then glued on a plate of 1/16 ply, covered it up with white Monokote and screwed the LG to that. Of course I had to shorten the tank cover.
