This wing type may seem a little crude to some, but the airfoil used here is simple and quick to build, does not come out overweight and is sufficiently efficient for a sport model. The fact that the tailless wing planform is unusual should not put one off building it as it is a surprisingly good performer.
The power recommended is small, so will not be costly, but the turn of speed is surprisingly high, giving the model a moderate climb performance and good slow glide. And, although it was not designed for aerobatics, it will easily loop and roll gently. Rolling, though, does need a lot of down, as the model becomes inverted, and the rolls are large and ‘barrelly’, so one needs a lot of height and some practice.
Perhaps a good description for the model would be to say that it is suitable for large park flying for someone with a little experience in building and flying. The wing build is probably the easiest you have ever suffered! Controls are by elevons only. My model is powered by an economy motor, a D2836-7 (1120 kV), a 40-amp ESC (as I had it in stock, although a 25A item would suffice) and a 2S-1800, 30C LiPo battery with an 11 x 6 folder prop. This combination draws 15 amps (120 watts total or 60 watts per pound) at full throttle and the ready to fly weight came to 33 ounces. A more powerful motor would be possible, say one with a load of about 100 watts per pound, but I do not see an advantage to this as the Jedelsky airfoil will be the limiting factor on flight performance.
