We have had a lot of Kavalier's in our club. One guy had an Enya 35 in his (this was in 1980's), and it flew fine.

My own Kavalier was built in 1978 by my father, and it has always had a 45 or 46 size engine. That is plenty of power. It is still airworthy, but I have not flown it in the last year or so. I agree with Thud_Driver. It is certainly an excellent flying airplane.

Best regards,
