I have been out of gas models for 20 years but may build an old pattern ship that called for a .60 size engine. I don't think I want the complexity or cost of a 4 stroke.
I need suggestions for a strong runnig 2 stroke. Are the Tower engines any good or should I stick with OS or Super Tigre?
Thanks

Most of the newer .60 size two-strokes are built in larger crankcases than the old pattern engines that we remember. Especially OS and Super Tigre. These two manufacturers have one crankcase size for their .61 thru .91 sized engines. This makes the .61 heavy and large and the .91 weaker than the old .91 engines because of the smaller porting area (bypass port).
Rossi still sells good .61s for old pattern flying and there is a company in the US named MECOA that sells high quality versions of the old Kraft .61 and HP .61, if you can find them in stock. I haven't managed to as yet.
I recently went to eBay and bought three used OS .61 SF engines. These will fly my old pattern models just fine. Yes, it is a crap shoot and you'll pay a good penny for them. So far it has been worth it to me. Would have bought new Kraft/RJL engines if they had been in stock.
