The New Evolution Engine?
I have two of these and they work, just like there supposed to,every time I go out. The fellow teaching me to fly is quite amazed, and yes he wanted to fiddle with adjustment, but was dissapointed when it only required a click or 2. Having no experience with model engines I would definately recommend them. One less thing to mess with, lose the three blade prop and flywheel and you got a fair amount power. JW
