KO TECHNOLOGIES METHOD F 2307 (2450KV)

The Method F motor is the culmination of a huge amount of testing and R&D. The motor features a full removable base plate, and wet sump along with cryo compatibility at an overall weight of 35g (with short wires)

KO tech is the very first motor company to incorporate a cooling system to RC brushless motors that does not rely on fans or fin style designs .

The traditional fan or fin styled design calls for a fan machined in to the bell with on the inside or outside of the bell, this method has 2 major flaws. Firstly this design is” handed ” meaning CW rotating motors must have a fan design orientated differently to a CCW voting motor if the fan is to be effective. Second is the fact that a fan or fan shaped spokes design robs the motor of power to drive the fan and In turn lowering response times, ultimate RPM and ultimate available torque.

KO tech has developed ACPC to compress oncoming air directly at the bell spoke face forcing the air past the spokes and directly into the stator and magnet assembly.

This lowers the temps increases torque and dramatically increase response times all the way along the rpm range. As a bonus the angled ring that forms the ACPC design is used as a counter balance used to reduce the amount of putty used to balance a motor bell.

We are able to “clock” the ACPC ring a full 360 ° during the balance procedure effectively halving the amount of putty needed to achieve a reading of “True” on the test equipment . This allows us to further reduce the bells weight and in turn improve motor response times.

Lastly because of this ability to reduce the amount of balance putty putty needed we have also been able to reduce the lip at the base of the motor used as a rebate to retain the putty under high RPM centrifugal forces further reducing weight and Improving response times.
