    Fantastic

    I got 2520 at an event for my little heli, wanted to test out the Tengu - and the power is so different, I almost don't recognize my heli anymore.

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.

What is the correct timing and frequency fo the Tengu 2520HS?
Usually the best timing for the Tengu 2520HS motors is around 8-9 degrees of timing (based on Hobbywing) and a PWM rate of 32 should work just fine. The best way to check if the timing for your motor and setup is correct, is by measuring the temperature after flight with a laser thermometer (temp gun) - it should ideally be between 40 and 60 degrees celsius.
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.
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.
