Just made a deal on a World Models Super Sports 40 that comes with a Super Tiger .40 motor. I own a Magnum .40 XL and one of the new Evolution .40 motors but do not know much about the ST 40. Anyone had good/bad experiences with them. Any tips, etc?

Thanks,

The ST 40 is as good a engine as you can get for less than a $140. We are not allowed to use nothing but the ST 40 in our clubs 4*40 races. Generally we run 2 tanks of 10 or 15% Cool Power and run sloppy rich for breakin. The motors are highly reliable, very powerful, consistent and cheap. That is why we use only them for our races. After breakin you can get 14000 to 15000 rpm with a 10x6 MAS prop and 15% Coolpower. Not sure what plug I use but it is most likely an OS A3. I run a Webra 40 GT Speed and the ST 40 everybit as good in every way you measure an engines performance.
