Here is a drawing for the three motor array. This is probably easier for me than trying to rewind a different motor.
It is intended for a 9x7 two blade.
However, despite being a glass composite material, it is also an E-only prop with hollow-cambered blades, and I
am not sure whether it is rated for 22,000 rpm.
Otherwise I have a 3-bladed 9x6 prop lined up. - it has left-hand and right-hand versions, for a twin-prop model plane.
I will sort out loading for a 9x7 two-blade, and then de-rate the motor spec to aim at 100 A max , 50 A per 3-motor array... that may be a problem,
as these ones are 38 A each!
they are also 445 w or so each, but 200w each is probably enough.
Performance parameters desired are 105 mph, 2000 gf static thrust per prop.
