Specifications
All the products in our store are manufactured by us with great care. You knew that, but we get why you clicked the tooltip - and thanks.
The stator size of our motors is indicated as a combined number, where the first two digits refer to the stator width, and the last two digits refer to the stator height.
So a 4730 stator size refers to a motor with a stator width of 47 mm, and a stator height of 30 mm.
On large industry models with a stator diameter in exess of 100 mm (like our Jetstream Heavy Duty Series, these numbers are seperated by a dash, like 100-30 or 150-50.
The motor configuration gives you information about the number of stator arms/slots (N) and magnetic poles (P). So a 12N10P denomination refers to a motor with 12 arms and 10 poles.
This information includes the number of mounting holes, their respective thread size, and the bolt circle on which the holes are placed — shown as the number in brackets.
Example 1: "4x M4(30)"
This means that the motor features four M4 mounting holes, placed on a 30 mm bolt circle.
For extended compatibility with a wide range of models, some of our motors feature a combination of different mounting hole sizes and/or bolt circles. In this case, the information is shown as follows:
Example 2: "2x M4(30) + 2x M3(25)"
This means that the motor features two M4 mounting holes placed on a 30 mm bolt circle, and two M3 mounting holes placed on a 25 mm bolt circle.
Don’t worry if only two of the mounting holes, opposite to each other, line up with your mounting bracket or motor plate. Using only two screws is perfectly fine — but as with any metal thread, always use threadlocker.
This number refers to the legth of the motor body excluding the shaft, so from the mounting plate to the top of the rotor.
This number refers to the width (maximum extension from side to side) of the motor.
When checking the clearance in your frame, this is the number to compare it against.

Thank you for 10 amazing years
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.
Nachdem ich mit ein wenig Hilfe von den Jungs mein Timing richtig eingestellt hatte, ist auch die Flugzeit mehr als beim alten Motor - top Motor, top Service.
Ich habe den Egodrift 2520Hs 1880KV in meinen T-rex 450 und ich kann nur eines dazu sagen dass der Motor einfach spitze ist. Ich habe beobachtet dass der Motor kühler bleibt als mein Vorgängermotor, auch die Leistung ist deutlich höher in Vergleich dazu.
Die Flugzeiten sind dadurch etwas kürzer jedoch hat man mehr Flugspaß!
I tried almost any motor available for 450 class helis in my OXY 4. Since this is a pretty critical size, many components such as batteries, servos and motors can be pushed to their limits pretty fast. I managed to smoke two Scorpion motors in one month. That's why I thought to give the Egodrift Tengu a shot.
This motor remains a lot cooler than any other motor i tested. After about 20 flights no play so far.
I also like the properly dimensioned connectors. Most of the other brands just give you 3/3.5mm banana connectors, which are semi-optimal due to a higher resistance.
I can recommend this motor to every pilot, because it's efficient and powerful.
I have Tengus in several of my bigger helis, so when the 2520 was announced I was quick to order one to upgrade my Gaui X3
