Part 1
I have done one before, with triple brushed motors, but this time I have gone with brushless, fwd/rev esc's, and twin props. I designed and printed an assembly that places the motors and shafts in perfect alignment. I have also created shaft covers that go inside and outside of the hull to keep the shafts supported and at a uniform angle. More to follow....
