Details

EGODRIFT Tengu high-performance brushless motors for RC heli are the result of one year of testing and development. The 4020HS comes with a kV rating of 1050kV for 6S LiPo batteries and is the perfect choice for your 500mm sized SAB Goblin, Synergy, XLPower, Quest, Hirobo, Mikado Logo, Align T-Rex, Gaui or scale helicopter model.

The dipped stator is hand-wound with 1.5mm high-temperature wire and delivers a continous power of 2040W (2640W Peak) at a continous current rating of 85 Ampere (110A Peak).

The motor's overall dimensions are 45 x 49.6mm (1.77x1.95 inch) with a total weight of 290 grams (10.229 oz). Several shaft options available.

Like all models within the Tengu series, the top of the can features the iconic and heat-resistant EGODRIFT Stickerbomb print, to add the finishing touch to your 500 class heli build.

Each motor comes with mounting screws and an (optional) screw for additional securing of the bell.

    Power upgrade for XLPower 520

    I got the XLPower 520 in a kit with an XLPower motor, but was curious for the difference to the Tengu. After having tried both in the same heli, I can safely say these two motors are very different: The Tengu runs cooler, uses less battery and outputs substantially more power

Product Questions

What makes HAND-WOUND motors better?

At EGODRIFT we rely on the art of hand-winding motors for every single one of our models (with no exception) for a variety of reasons:

1) Fill grade - packing more copper
While machine winding would certainly be a whole lot faster, cheaper and easier, there are a few technical downsides to using winding machines: The biggest one of them being the achievable fill grade = how much copper (wire) you manage to squeeze into the bell around the stator arms. A winding machine relies on bigger (and static) tolerances to wind the wire lobes around the stator and cannot adjust it's winding routines as good as one of our winding experts can with every lobe. They wrap, pull, push and fit the wires around the stator to manually reduce the empty space between windings to the maximum, thus achieving a higher fill grade in the bell than a machine could. Think of empty space inside a bell and between the stator arms as wasted potential. And for copper on the stators the one thing that holds true is: the more the better.

2) Quality control - Each motor is going through our experts hands
By winding each stator manually, we ensure that all components - the stator itself, as well as the wire, and the finished assembly - is going through the hands of our winding experts for several minutes. Any imperfection in the material or the assembly will immediately be noticed and any products that fail our rigorous standards when it comes to winding our stators can be discarded immediately.

3) True craftsmanship - and not mass production
Our lovely winding ladies have been building motors for us for well over a decade, and we will continue to rely on hand-winding for many years to come. We believe motor winding by hand is an art, and a skill that needs to be preserved. Each one of our motors is a piece of true craftsmanship, not the result of mass production. And we love our staff, and feel it's our responsibility to secure their jobs for the community.

Do you ship to Germany?

We currently ship to over 40 countries worldwide and - of course - to Germany as well.

As our shipping rates vary over time (and this answer might accidentally remain unchanged), we kindly ask you to refer to the shipping cost calculator in the cart page to find the actual shipping costs for each country.

What does 12N10P mean? I need this for setting up my YGE 205 telemetry capabilities
This abbreviation refers to the layout / winding scheme of the motor. The first part (N) translates to the number of arms (wire wound poles) on the stator, whereas the second part shows the number of magnets (permanent magnetic poles) on the rotor. So a 12N10P motor features a stator with 12 arms and 10 poles (magnets). Usually the number required for the esc is the second part.

What timing should I use on the 4020 1050kv motor using a 120a hobbywing esc?
Our HS series motors tend to run best on a rather low timing, and we usually recommend starting at 9 degrees (on Hobbywing), and to test fly the heli (and measure the temperature with a temp gun after flight). If necessary, you can adjust (fine tune) in +/- 1 degree steps from there.

Can you do a custom wind / motor with special kV for me? What are the costs?

Thank you very much for considering us for your project. As all our motors are hand wound, it is fairly easy for us to fulfill your special kV requirements with a special wind.

Finishing your custom kV motor usually only takes a day, and is offered by us free of charge. Please send us a quick message stating the model (stator size) and kV you are looking for and we'll get back to you in no time.

We're also happy to consult you on your motor choice if you send us a small description of what you're trying to achieve with your setup.
