RE: Great Planes Giant Ugly Stick
That is why my friend and I use them for formation flying. They are the best bang for the buck so to speak for a larger gasser and is easy and quick to replace when in a mishap. Not bad for being our first after about three years of flying like this. For power we have tried OS 1.60, Fuji 43, MT 57, DLE 55, DLA56, and the DLE 30. I find that the DLE 30 has shown the best overall performance. The newer 35cc engines from DLE, DA and others would be the best but I already have a 30.
