I put a DLE 20 on a DRASTIK 60. On a 16x6 prop, it puts out about 12.5 pounds of thrust on a 8.4 pound air frame. It is the best flying stik that I have ever flown. The engine has a Bowman ring and the reed valve has been trued. It has really crazy power even at 5500 feet elevation. At Texas RC Planes there is a video about the Drastik with the DLE 20. That convinced me to buy the Drastik and put the DLE 20 on it.
