I had an RCG 20cc Gas engine, Sullivan smoke pump, one tank for gas, one tank for smoke oil, ignition battery and receiver battery in a Christen Eagle 90 like this one but it got way to heavy. 6,2kg take off weight. It produced good smoke but it flew very badly. The plane in this video is a new model With O.S. MAX120AX glow engine and no smoke system. About 4.5 kg take off weight now and it flies great. I think for smoke system a bigger Christen Eagle is better or if you use a crank case preassure smoke system and no smoke pump you might save some weight.
