KO Method SWR 2210 Motor

The Method SWR was designed to use in wing racing guidance and to provide an efficient powerful alternative to what is currently avaialble in the market. 

This motor offers  a number of industry firsts that you will not find in any other brands. With a removable base plate.

The SWR is designed to be used on a  light weight  Spec wing styled aeroplane equiped with a 3s-4s battery and a 6x4 plastic APC style propeller. But if you want you can use that motor in larger wings with higher voltage or larger but you should test your wing by slowly increasing throttle persentage and flight time while checking opperating temperatures at each stage until an optimal speed / efficiency has been achieved.

KO tech is the very first motor company to incorporate a cooling system to  RC brusless 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. KOtech 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 ballance 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 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.
