I recently purchased a evo 61nt here from rc uni and am really impressed with this engine. Runs great just put it in the plane and flew it after minor adjustment. Its on my tiger 60 and does a superb job.

Note I had to return a os 46 ax, peeled liner the motor was replaced but thats when I started looking at other brands. I really have good luck with all brands but the evo is priced better and the performance is equal or better. Just my opinion...
