I've owned Super Tigres in the past and found them to be very powerful engines. I am running a couple of OS Max 61 SF right now and find them extremely powerful. They are at least 30 years old.

I have a Evo 61 NX still new in the box, I don't know how they rate as power as yet. It's hard to get good information here because you have those they say they are the bee's knees and others that claim they're junk. So who do you believe?

I have flown Webras, O.S. Max, Fox, K&B, Super Tigre, Picco and McCoys. I found that the Picco was the strongest, followed by the O S Max , Webras and Super Tigres. Fox was my worst engine. The McCoy Red Head was my first engine back in 1958.

Dub Jett makes one fantasic engine. I wish I could afford one or two.
