OS 61 SF Engine Featured Engine: OS 61 SF

But I find that two stroke nitro engines are still a very effecient, reliable, and inexpensive way to fly medium sized planes. A sport flyer would be remiss not to consider two stroke nitro engines for power. Listed here are a number of preowned new and used options that might interest you.
