Just for fun, flying my old TARC design on a full-AP cluster of 2 AeroTech D10-7W's and 2 of the new E20-7W's. One of the D10's didn't light (though with all White Lightning motors, it was as good as I had hoped for), but the flight was otherwise a success, and the spin tabs worked well to prevent arcing from the slightly off-center thrust.
