From Rotorgeeks:

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!

As with all Rotorgeeks motors, 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
  • The little things
    • 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

Thrust charts will be posted shortly but keep in mind the limited value of static thrust tests as this size motor is usually current limited by the small batteries.  Power combinations that burn up on the test bench work in real life without incident.

No hollow shaft?
We prototyped with the trendy ‘hollow shaft’ design.  It added weight in an area where there was no requirement for additional strength when using 7075-T6 Aluminum.  A steel shaft also restricts the inner diameter of a stator, which is undesirable when designing a small, light motor.  The only motivation we could fine for a hollow shaft in this size motor was cost savings (the block of aluminum that the rotors are milled from can be substantially smaller without the height of the prop adapter on top).

Domestic Shipping within the USA

By default we ship via USPS (United States Postal Service) to anywhere in the United States. But, if you are interested in a faster option such as DHL email us at info@catalystmachineworks.com and we can give you instructions on how to get expedited shipping. If you want expedited shipping be sure to email us prior to checking out with your order. We will arrange a shipping quote for you and then give you instructions on how to include this shipping option at checkout. Our USPS shipping option usually takes 2 to 4 days to reach anywhere in the USA. By default this shipping option will NOT require a signature. If you want us to specify signature required please let us know prior to placing your order. 

USPS Insurance 

USPS shipping includes $50 insurance by default. If you require more please let us know prior to placing your order. PLEASE NOTE: We will not be held liable in the event your package or package contents are lost, damaged, or stolen during shipping. When your package leaves our shop and is placed in the hands of the shipping service it is out of our hands. We have no control of what happens to your package after it leaves our doors. Shipping insurance it available to protect you in the event something happens to your package during delivery. We will not reimburse you for lost, damaged, or stolen items. That is what shipping insurance is for. If you would like to add shipping insurance to cover the value of your purchase email us at info@catalystmachineworks.com for more info. 

International Shipping 

We can ship to almost anywhere in the world! Available international shipping options are using United States Postal Service (USPS) or DHL. USPS shipping will be per the flat rate option. This is $28 and can take 6-10 days to reach your country. From here your country postal service will deliver your package and can add additional delivery time. Usually USPS tracking ends once the package reaches your country. Our second shipping option is using DHL. This is considered a premium option and is very fast. Customer service with DHL is the best in the shipping business. Typically DHL only takes 2-3 days to delivery to most locations throughout the world. DHL international shipping always comes with tracking. While this is a more expensive option it is much better than USPS.
