G.F. Reid,
Good to hear, I may just do that. I just completed a Balsa USA 1/4 cub with Ryobi @16lb, and from level flight it will just loop falling out at the top just a little bit. Might be interesting with a CH ignition to shave off a few ounces and hopefully shoot for something just under 14lb. I think the ryobi and Mculloch are about the same in the weight dept. Ryobi is a little longer though. I actually would like to make it a little more like a Stearman, reshape the tail feathers round out the fuse sides just a touch and slap on a round cowl.
