Enya has been producing some of the highest quality engines for as long as I've been in aeromodelling. If they had been readilly available... I probably wouldn't have even tried an O.S.

Fox has always made good economical engines. I never tried ther higher end ones... but had very good results with every low cost bushing type that I bought.


There's lots of good engines on the market... O.S. certainly is one of the better manufacturers, but there are other good choices.
