25g 2305-1500KV CSP


Though Twisted Hobbys is known for airplane designs we are also well known for creating some of the most powerful small motors available and Crack Series Pro are the perfect example!  We have done it again, we have surpassed our most popular small out-runner and redesigned our 26g Crack Series motor.   Our focus was to create a more powerful, better balancing higher acceleration along with high quality parts and manufacturing then ever before. The all new fixed prop hub allows for easy install of prop saver band assembly.  Shallow height can for increased prop stability, high grade magnets with a new winding along with a hollow shaft allows for ultimate spoil up, cooling ability as well as increased thrust output.  Also we have increased the hardware spare parts for more prop saver hub's since they have been known to get lost, also more o-rings are now included.

Quality without compromise! There is no mistaking the quality, reliability and overall performance of our Crack Series out runner motors.  Tested, proven to outlast and provide you with endless flights!  Running 2s or 3s the 2305-1500kv is capable of 60-120 watts of power using standard 8" prop setups.  The 5.5mm integrated new hub design works directly with our APC,GWS or Tuff Slow Fly props.  Twisted Hobbys "Crack Series PRO" 2305-1500KV 25g Brushless motor can be used for any 6-12oz foamie model.

    Very good little motor.

    A very strong, trouble free little motor. Excellent choice for the Twisted Hobbys F-22 Jet, the Mustang racer series and the Zoro wing. Plenty of power and very quiet. My only complaint is that the prop-saver hub is not removable. If I could use a conventional prop adapter on this motor it would be five stars all day long.

    Good strong motor

    packaging was good in bag along with hardware screws orings and small alum disc's.
    Connectors are done for you which i liked.
    Wires are short though worked fine with matting esc wire lengths.
    Pulls strong on 2 cell and no heat cool to touch.
    Runs smooth not noisy sounding.
