DJI motor Grey 300.

The motors are not the traditional red, are somewhat more guys, and 50 grams, 2212-920 with 9.5 x 4.5 propeller and 15A esc.

The ESC brings battery cable with coaxial or shielded.

My tests were as follows.

No Load.

M1 = .47A, 10,400rpm, 11.67 V, 891 Kv.
M2 = .54A, 10,450 rpm, 11.73V, 890 Kv.
M3 = .50A, 10,200rpm, 11.62V, 878 Kv.
M4 = .44A, 10,150, rpm, 11.58V, 876Kv.

With prop stock. 9.5x4.5

Mi = 8.14A, 7,800rpm, 11.36 V,% NLS. 77.1
M2 = 8.28A, 7,900 rpm, 11.40 V,% NLS. 77.9
M3 = 7.86A, 7,900rpm, 11.31 V,% NLS. 79.6
M4 = 7.79A, 7,800, rpm, 11.28 V,% NLS.78.9

This motot is not you can put bigger propeller because even with this, motor is quite hot, but not enough to consider not accelerate fully.
Practically this limit in its 94 watts.
94 watts between weight 50 grams is 1.88 watts per gram.

Nothing to do with what many brands claim 3 or 4 watts per gram.

Vs Multistar 2213-935.

No load. .57A, 12.09V, 10,350 rpm, 856 Kv.

APC sf 9x4.7, 9.35A, 11.76V, 7800 rpm, 110 W. 77.5% NLS.
10x4.5 stock. 10.97A, 11.37v, 7100 RPM. 124.7 watts. 72.9 % NLS.
GP 10x5.5 11.65A, 11.73V, 7000 rpm, 136.65 watts, 69.7% NLS.
APC SF Clone. 10x4.7. 12.85A, 11.44V, 6500 rpm, 147 watts. 66.4% NLS.

For what I see, these two motors, if they have the same system and if they can share the propellers.
Al Multistar you can put the propeller of DJI.
When the motor DJI, you can put any with multistar propeller nut.

Unfortunately when multistar motor had in my hands, did not know the DJi.
And now i have only DJi motors.

I'll try to provide the multistar, for tests with DJI 9.5x4.5 propeller.
But being of a lower Kv, the performance will be lower.

Multistar MT2212-920 differ lightly to MT2213-935.
You need to know your true Kv to see if it is a direct replacement for DJI.

I think they are called DJI style or DJI fit depending where you look.

I just got some of the self tightening since it appears they fit on the DJI motors like this so we will see how they work.

DJI motors run fine on 4s power with 9.4" prop. Multistar is a 3s only motor, it is not comparable.
