I have both the "old" foam wing, short tube, and it needed a false ply rib added at the end of the balsa tube socket box. Okay after that.

The "new" is the fully-built up wing, and the tube extends into the wing 10.5", still 25mm diameter, and seems to be inserted into a socket that is anchored at each rib, with a ply doubler at the outermost rib. At that point, it looks to be tied to the upper and lower spar with that rib.

Haven't test flown it yet, but it came out the same weight as the foam version, but several improvements made.

I *really* like the way she flies, else I wouldn't have TWO. OS 1.60's for power, Mac's tuned pipe, Perry Pump, Mueller header, doing about 8100 with an APC 15.75 x 12 three blader. Std. APC 17x12 goes at 8400, and is WAY too fast.

*LOVE* the snap entry, and roll damping....If I could just get a cleaner "break" at the spin
