Manufacturer Scorpion

The Scorpion A - Series line of motors was designed to be the most optimal and premier choice of motor for your freestyle or UAV airplane. We have achieved incredible performance through incredible efficiency. By optimizing the magnets in the rotor, and using the best quality 0.2mm thickness silicon steel stator sheets, and single strand enamel coated copper wire windings rated above 200C+, the performance and efficiency results are unlike anything we have seen before! Combined with a robust design which has been tested extensively by our world class team pilots for longevity and reliability, we feel this motor checks and exceeds all measurable categories!

The A-7445 was designed specifically for airplanes requiring a 150cc - 170cc equivalent gas engine, or other airframes requiring up to 10,000w of power.

Recommended Prop Selection :

  • For 12s - 29x13C2E / 30x12 C2E / 32x10C2E = 150cc -170cc performance
  • For 14s - 28x12C2E - 30x12 C2E = 150cc performance

Recommended ESC -: Tribunus II 14-300A ESC SBEC

NOTE: Due to the large size of airframes in this class, normally the battery wires must be extended. Running to long of battery cables WILL damage ESC and void your warranty. Precautions must be taken. We recommend the use of the Scorpion 1880uF Capacitor / PDB Board

 Tutorial / WARNING about using ESC's with a Power Supply, or Long Battery Cables

NOTE: Due to the large size of airframes in this class, attaining proper ESC cooling can be difficult. The ESC MUST have direct access to airflow using baffles directing air directly to the ESC. Simply adding a hole in the cowl is not suitable, and air must be carried directly to the ESC via baffling.

Acrobatic Weight Range -: 15.0kg - 25.0kg - kg (33.0lbs - 55.0lbs)

Sport / UAV (single engine) Weight Range : - 21.5kg - 64kg (47.4lbs -142.0lbs)
