AM/2830/850 Brushless Outrunner

The Airtek AirMax Series are our fifth generation Motors following in the footsteps of our hugely popular Excel, Apex and Apex Pro ranges. These motors provide the modeller with the best value outrunners you can buy. Notice the word value, for although these motors may be budget priced the specification is certainly anything but. Featuring 12 Slots and 14 Poles to generate the torque demanded by the serious modeller, CNC Machined from top grade 6061 T6 Alloy and high purity copper windings for maximum efficiency. Add to that ABEC5 Oversize bearings and a stator from super thin (0.2mm) laminations, plus each motor is balanced at the factory for the ultimate in smooth running!
Don't be fooled by the low prices, we achieve these by being a first tier supplier, these are manufactured to our specifications and there is no middleman - so you get the best for much less!

* These are the MAXIMUM Watts the motor is capable of attaining and not what you will normally get in a real life situation. The cell count and C rating of the battery will both have an effect on the Watts attainable. An average sport lipo can lose around 1 volt per cell under load and this must be factored in when calculating the realistic maximum watts you can attain.

** Recommended ESCs shown are based on you keeping within the operating parameters and specifications. Where space and weight permit consider using an ESC with a higher rating than recommended (i.e. where a 30A is shown fit a 40A) to give plenty of leeway.

*** Props are shown as a guidance/starting point. The prop is the single most important variable on your brushless system. The loading on your motor, and parameters such as AMP draw are (in broad terms) determined by the prop. A higher Kv motor will spin a smaller prop at higher revs, and a lower Kv motor will spin a larger (and generally more efficient) prop at lower revs. Props from different manufacturers with the same size can give very different readings (which can easily be determined by the use of a wattmeter), so experiment to find the best combination for your model. As a very general rule of thumb where the specified prop is, for instance, an 11x5 and you wish to swing a 10” diameter but want to retain the approximate same load on your motor you would compensate for the loss of diameter with an increase in pitch, so from 11” to 10”, and 5” to 6” i.e. your 11x5” would be substituted by a 10” x 6”. With folding props allow for the diameter of spinner used. An increase in spinner diameter effectively means an increase in prop diameter which must be factored in when choosing a prop size. Always remember, less cells = larger prop, more cells = smaller prop.

I.C Engine Equivalent

This motor is a very approximate equivalent of a .15-.19 Glow Motor

Electric motors and i.c. engines are two completely different forms of propulsion and as such direct comparisons are often not the most appropriate way of selecting a motor. However we appreciate that brushless motor sizes are very confusing for those coming over from i.c. powered models so have included this information to give you a general approximation. Electric motors are much more flexible than i.c. engines, being able to utilise a broader range of props. It is possible to choose a motor that turns a same size prop at the same revs as an i.c. engine, but you will get a much better performance if you utilise the flexibility of brushless motors correctly.

The specifications above are supplied in good faith. As with all electric systems there are multiple combinations of Motor/ESC/Props and Batteries available, the change and variation of any of these (even the same size/specification from different manufacturers) will have an effect on the parameters/performance you can expect. We STRONGLY recommend the use of a wattmeter. These relatively inexpensive devices will not only bring some science into your hobby, allowing you to optimise your set up for better performance and duration, but will check if you are running within the limits of your equipment. Your first fried motor or burnt ESC will pay for a wattmeter! If you don’t use a wattmeter always check the temperature of your Motor/ESC after a run. Warm is OK - hot is NOT!
