Sunnysky R1106 5500 RPM/V 8g Outrunner

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 4.7×2.3) 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%.
