Evilutiona are an excellent motor, I've had a few of them now and never had a dead stick with any of them. You do need to pull the limiter pins out of the high speed needle though, ecspecaily if you're at high altitudes. I've never had any of the needles move either during flight which some have had happen, I just pull the needle out and bend the tab slightly and re-install the needle so it is a little harder to turn. Just remember that these motors use a 4-stroke plug, such as the OS "F" type plug and not a typical 2-stroke plug. I fly at almost 6000ft and ocassionaly around 10,000ft and have had no trouble with RPM's. I do use and have always used 25% nitro fuel and it runs smoother and they all run strong. Just like any other motor, if you over heat it it won't last long. PM me if you have any questions.
