The Rotorgeeks 1407 continues the tradition of high performance, tough, serviceable motors.   Originally designed in April 2016, the 1407 has undergone 4 major revisions in quest for the ultimate lightweight powerplant.  The final version is a top performer in its category as well as the lightest, coming in at only 14g with locknut! The 1407 is made from 7075-T6 aircraft grade aluminum, with almost 3 times the tensile strength of traditional 6063.  The case design has been engineered for maximum strength and impact resistance.  Shafts are secured into the rotor both mechanically and with a high strength adhesive to make shaft slippage and vertical play a thing of the past. No set screws are used (unlike Brother Hobby, X-Nova, DYS, RCX etc).  The shaft is held in place at the base with a standard e-clip, making servicing and parts replacement easy.

Single wire winding - offering high current capability and heat tolerance. 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, stator, bearings


- Dynamically balanced rotors
- Case design engineered for light weight and maximum cooling and airflow to the windings. 
- Greater clearance from the base to the windings to afford more tolerance on long mounting screws without damaging windings
- Japanese NSK bearings
- Compression washer loaded to control vertical play

Rotorgeeks has been running the 1407s in various configurations – it's a very flexible motor, typically running on 3-4S power with 3” and 4” props.  They’ve run the 4000kv on 4S with props as high as the Dal 4045 V2.  We’ve even run the 3200kv on 5x3.  In most cases the battery is the limiting factor rather than the motor.  All of our test machines have been running the very small and light Cicada 10A ESCs which can run DSHOT (up to 600) and handle 4S voltage.  Alternately the Cicada 20A 4-in-1 ESC is a good choice for those that want to run their electronics in a stack.
