Honestly Gary, Icouldnt tell ya exactly. I know I reinforced the two areas that i mentioned earlier and after some thought, I recall doubling some plywood for the landing gear and some spots inside the fuse that looked spindly to me. The .46 wieghs a bit more than what a .25 would so that accounts for SOMEof the extra weight but I am not sure why it is so "heavy". I can recall my epoxying methods werent very good back then either, perhaps there is a little more than is needed on there somewhere. Truth be told, I'm plum tickled with its weight and Ididnt have to move anything to balance it either! Ican certainly say the thing flies beautifully and Ican set it down and have it stopped inside 10 feet on the runway since she can be flared til he!! wont have it!

my runway is 300ft and have no problems on take off.. how long is yours?
