While the 2809 size isn't new, this motor is built with the latest components RCinpower has to offer and parts we've found to perform well. Various adjustments and quality of life improvements include bell durability design, bearing accessibility, flush mounting, magnet heat dissipation and other minor details. The 2809 size was chosen because of it's proportion of width to height providing good permanent magnetic flux, adequate stator heat dissipation, good efficiency, good motor weight and excellent low and high rpm control for typical 7-8" loads on 6S with it's 1300kv. We did experiment heavily with split shifted magnets and other various design elements prior to settling on this size and build. The added cost and performance trade offs in other areas were not worth the very minor improvements.
Our favorite prop with this motor is the Gemfan carbon reinforced nylon 7035 triblade. Pair all this with an 1800-3000mah 6S pack with a high C rating for excellent performance.
This 2809 motor replaces the previous 30mm motor and has the latest magnets from RCinpower. You can mix and match this 2809 with the 30mm motor on the same craft.

Using these on a 7" build. They are amazing. Plenty of torque yet still very efficient. I spend most of the time flying at half stick or less. Great motors and super smooth.
Perfect motors for 7-8” longrange/ cinelifters! Great quality and performance.
Powerful and smooth. Huge improvement over previous 7" motors. They have been holding up well. Have more than 50 packs on them with no issues. Even after spending the night on the bottom of a lake on their 3rd flight.
awesome motors unfortunatley my 7 inch frame has not arrived just get run arounds just wish i had a reliable company to sell me what i ask and pay for. .thank you very much for the motors my 13 mm 5k kv on my tp3 is sick btw thanks again
