That had occured to me. Take an ultralight, swap the pilot for drone control. Result: lower stall speed, faster climb, regulatory hassle.How about an unmanned tug?
That is a good point I hadn’t considered. Sandlin’s other designs have full 3-axis controls, I’m sure that ailerons could be added for a weight penalty. You’d want to analyze the rear tube spar to make sure it could handle the aero loads.I think the Bloop uses rudder and would not yaw to rudder control if it were limited by a tow line. The trikes use weight shift to induce bank and don't care about yaw.
