Thanks guys. There is more than enough cooling fin area to keep these engines cool. They dont run hot and they dont die. With a pump style carb the chance of getting a lean run is not as great. All I can tell you is to try one or wait for the customers to post there results on RCU. I guaranty you will love it. They work great on any .60 size plane like a BME Cap maniac, Aeroworks .46-.60 Edge, stick style airplanes to warbirds. Its insane power on most .60 sixe planes with no weight penalty. The 55cc will be ready for sale in April.
