I may be wrong but those three engines should give about 5HP. ?
I'm not very good at those type of calculations so maybe someone who
knows these things will chime in here?
I'm cutting her weight everywhere I can and still have a strong plane.
THE GOOD THING IS IF I need a bigger engine the center one can be larger there's much more room there.
Alright this afternoon I went back in the shop and made ribs 2, 3 & 4 and checked there orientation it's looking good so far.
You'll see where the tube will go since I went bigger w/ the tube it will be sandwiched in between the rear main spar; you'll see a line where I'll cut then flip the piece of 1/4" ply over and the groves will line up coming up from the bottom sandwiching the wing tube, this will all get glued in really good once it's correct.
It may seem like it takes me along time to make a few pieces but remember I'm making templates each time for every part then cutting out the plywood pieces and fitting them.
Check the days progress,
