I always use some epoxy. The fuse broke when it went into low weeds on the side of the runway while still on the ground and not rolling very fast(too fast obviously). It broke behind the reinforcement. Absolutely no other marks anywhere and after only a couple of flights. People have been flying into those weeds without damage for a long time. The lite ply broke. Just remember all ply has voids, especially lite ply and especially in 2002. It is not what it was a few years ago. I sheeted the leading edge, reinforced behind the wing and a few other things. With the YS 91 FS the CG came out bang on, so it is great. I now have reinforced further down the fuse and I am happier with it. BTW my landing gear and the fuse above are strong enough without any mods. Whatever one wants to do they shoulld do. Rajul if you build it you can fly it, if you ponder building it you can't!!
