The best selling ParkJet motor since 2002! GraysonHobby was worked closely with our manufacture for several months to develop a affordable ParkJet Motor; which is a high speed high KV motor for smaller parkjets and parkflyers. Prop range is limited due to the High Kv (2200) rating of this motor. Use with 3 cell lipo battery capable of sustaining 20 amps. Prop range is from 5x5 to 6x4.
The motor features a 3.17mm hardened steel shaft, dual ball bearings, and has 3.5mm gold spring male connectors already attached and includes 3 female connectors for your speed control. Mounting holes have 16mm and 19mm spacing on centers and are tapped for 3mm (M3) screws. (ie if the mount does not fit, turn it 90 degrees)
