The Racerstar AirB is the second motor to come out of the partnership with Racerstar and T-Motor. These motors are well designed, look fantastic, and also feature quality components.
If you have bought Racerstar motors in the past, and found the to be pretty shoddy; you will at first have a hard time believing that these motors are from the same company. Both the AirA and AirB are great motors. So the involvement with T-Motor has definitely shone through. The machining, bearings, windings, and overall finish are all top notch.
The AirB is a 2514 stator motor with a KV of 1498. It can run from 3S all the way up to 8S, with a maximum power of 1139 Watts or 45 Amps. Suggested props are 4S – 8″, 5S – 7″, 5S & 6S – 6″ tri-blade, and 8S – 5″ tri-blade.
