RE: Tiger .60 . Building suggestions?
I have built 3 Tiger 60's, all were deluxe kits with retracts. All were set up with the nose wheel set up, and O.S. 61FX's, two of the kits were built at once. Don't worry about the wanna be tail dragger syndrome, I thought that mine were tail heavy, but they were perfect. I also used the Dave Brown arrow shafts for the push rods, but that was my preference, and certainly not mandatory. CF is not necessary for the fuse, as it is lite ply. The first one was involved in a mid air. The wing was sheared but the fuse was in decent shape considering the impact.
Larry King at Goldberg told me that losing a rib on each side would really make this plane move out. The second 2 were already complete, or I would have given it a go. Flaps are not necessary, but since each aileron is on it's own servo, you could try to set it up with flaperons.
The retracts are a real nice touch for this airplane, and if you are not dead set on a 4 stroke, the O.S. 61 is a great match for this plane.
Good luck!
