These motors were spec'd for the hq prop 40mm triblade (model# 40mmx3gr-pc-1.5mm) The shaft is only 3.45mm tall, vs the full length of the betafpv 1102 22kkv which stands a full 5mm tall. From the base of the motor, to the bottom of shaft once again shorter @ 7.75mm, vs the betafpv @ 8.6mm. This will result in the props cutting into the frame on a meteor75 air (the props sit lower). While the hq props are EXTREMLY tight on the betafpv 1102's, they fit perfectly on these motors without the need to drill through the prop to press down all the way (shorter shaft mentioned earlier). They seem to fly really well though, while only a 1g auw lighter compaired to the 1102's they get around the same flight time. More testing needed.

For the longest time I couldn’t figure out why my whoop or toothpick were flying so poorly. Tried many different tunes with no help. Didn’t realize till I was changing props one day that two out of the four motors I bought had slightly thinner motor shafts causing the props to slip. It’s too bad since these are some of the more expensive 1002 motors.
