Well, I own a 102 Std III and have never had any real trouble with it,
but I think that the the most critical points are 1) having the right spar position marked on the bulkhead and 2) having a 1-man rig. The 1-man rig allows the weight of the wing to be supported at the center of the wing, so that there is no vertical load being supported at the inboard end. Those loads are being supported by the pin fittings that you are trying to get to slide togethor. They will slide better if they are not under load. Todd Smith Grob 102 3S |

The frustrating thing is that they all look just fine but the wing will still refuse to go in. I have tried (due to frustration) to wiggle wing fore and aft and up and down but that never helps at all Install the right wing, use a support a little inboard of the middle of the right wing (near the wings CG). When you install the left wing stand at the leading edge, and have a helper at the trailing edge. Support the wings weight while you slide it in (use your right hand ). If everything is aligned but it still doesn´t move, tilt the fuselage on its dolly very slightly (like a rocking motion) with your left hand to make it go together. A VERY slight, hardly noticeable back and forth motion on the left wingtip can help, too. Once you and your helpers have some training, it isn´t harder to assemble than any other glider. Michael |
