RE: 90 size engine in a 40 size airplane?
What plane and engine is the question. The old Global .46 sized Ultimate flew very well on a .91 4s. Some 46 sized planes have Saito 82's, I am running a YS 63 in a 46 sized plane. I ran a Magnum .52 on the nose of a 40 Ugly Stick.
So, what plane and what engine?
