HyperFlight have sourced the good quality SunnySky R1106-5500 outrunner that fits the
VM 25mm Spinner for 11xx Motors.
We measured the motor constants and actually found the Kv is 5600 RPM/V. The smallest available prop (VM or Graupner 4.7x2.3) is actually too large for this tiny motor and the power should be limited to 10A max by limiting the thottle channel throw to approx 50%.
