Modeltech Magic and OS .40 LA
I just got inside from running my engine outside undo the winter gunk in it. I have a .46 LA on a Great Planes Big Stik. Although it does run a bit rough it will pull my stik slightly verticle when held. I am using a Master Airscrew 10/7 and am guessing it weighs on the upper range of 5 pounds. In a sub 4 pound models it should have enough power to do well.
Ahhhhh...it warms the ears to hear that high wine of a glow engine. I just wish it warmed the hands, BURRRR!!!!
