LuvBipes,
If you modify the landing gear to attach to the fuse and remove the front center section of wing to clear the structure, you will greatly improve this model. The belly pan, in this case, could be permanently attached to the wing. Very nice set-up. Just modify the wing structure as req'd. My gear is attached to a beefed up plate with (4) 1/4-20 nylon bolts. I hope I don't put the wheels through the wing too many times.

BTW, that huge aluminum chunk of a gear strut is HEAVY. I may attempt to scratch build a fiberglass or carbon strut. He, He

The horizontal stab seems pretty sturdy to me. I guess with a hard enough snap maneuver...

How much does your friends Sukhoi weigh. Does it come in hot or float like the 10-300 does.

I also luv bipes and need an upcoming project. Have any recommendations.
