I ordered a Saito 1.80 today so I will be looking to reinforce the entire plane where needed. How about some tri-stock and fiberglassing at the firewall/fuse interface? Also epoxy everywhere the wood internal skeleton meets the fuse? Just not too much to add too much weight..and some reinforcement at the retract mounts..other than that what else?

As far as the Saito 1.80 goes I am hoping to mount it entirely (except muffler) in the cowl using the kit provided mount and predrilled holes or inverted if a cutout for the head is required. I just don't like inverted though cause it seems to be a hassle...I guess I'll just have to wait and see how it fits.
