Hello All
Has anyone built a B-17 from Paval Bosak plans? In the write up 4 x 3.5cc (0.21 cubic inch) 2 stokes are suggested, but on the plan 4 x 0.35 cubic inch 2 strokes are whats mentioned. My gut feel is that 4x 0.21's would be more than enough ( 76" wingspan ) as the wing area is huge and the 17 aint no rocket ship.
I have a twin with a similar wingspan ( but with a much cleaner shape and lower weight ) and 35's provide more than enough urge. I guess I am looking for some reasurance before forking out for 4 X 0.20's ( You gotta love those multi's )
Thanks and Best regards Steve
