Our time tested 2206 design wound to 1450kv for high efficiency, long range machines running 7" to 8" props on 4S or smaller props on higher voltage levels.

The 2206-1450 carries all the features of the RG 7075 Series

  • Single wire winding - offering high current capability and heat tolerance (up to 180°C).  Most of the high perfornance custom wound motors use this technique rather than multi strand wire.  Why is it unusual? The larger wire gauge can't be wound by machine...
  • Hand wound - even with all the automation available today, nothing matches the accuracy of skilled human.  The heavier gauge wire used in the Rotorgeeks motors demands hand winding
  • Fully serviceable - right from the start we wanted to be able to repair and replace every part of the motor to handle crashes as well as wear and tear.  Bearings are not glued in place.  All parts are available separately - rotor w/shaft, stator, bearings, clips and shims.
  • The little things
    • Dynamically balanced rotors
    • Case design was engineered for light weight and maximum cooling and airflow to the windings. 
    • The prop height has been set a little higher to reduce the likelihood of props striking the ESC. 
    • Greater clearance from the base to the windings to afford more tolerance on long mounting screws (without hitting the windings)
    • Japanese NMB bearings
    • shaft permanently fixed into rotor
    • N45SH high temp arc magnets and 0.2mm steel laminations for stator (we're still staying away from N52 for smoothness and efficiency)
    • Shaft and clip are completely recessed - the motor can be mounted on a flat surface without the need for a hole in the centre of the motor mount
    • Each motor comes with a hardware kit that includes a nylock flange nu and M3x6 hex head motor mount screws and washers.  The screws are good for arms ranging from 2.5 - 4mm thick.

Specs

The back story
Rotorgeeks has been proudly selling Cobra motors since before the development of the CM series for multirotors.  Cobras have always been great for quality and performance but their success has also led to availability challenges.  We began this journey with a simple objective - to create a motor of equivalent capability that we could actually keep in stock.  Matching the performance of the Cobra did not prove an easy task.  Prototype after prototype, we worked on every facet of the motor in the quest to match the Cobra, playing with different magnets, copper, winding techniqes etc.  Around June this year, we thought we had it based on prototype testing.  The first batch of motors arrived but the performance was still a bit lower than our objective and after much consideration, not good enough to release with the Rotorgeeks name.  A little more R&D and we landed on the final product.  The first batch of motors went back to China where they had the stators replaced (along with bearings and clips).  We're thrilled that at the end of a long road, we have the product we wanted.
