Think about an electric motor for your 5 (or maybe even 6) inch acro or FPV racing quadcopter. What do you see? Something in a 2205-2306 size range with a KV rating somewhere 2300KV and 2600KV. Sometimes even more. And it works great, as long as you wat 5-inch props and 4S batteries. You can choose and choose and choose between different models of different manufacturers. But what if you want to go 6S or 7 inches? You have a problem. Very limited choice of motors (and propellers as well).
Luckily, it starts to change and you can actually but lower KV 220x and 230x motors. I got my hands on EMAX RS2 2206 1600KV since I'm not very happy with TBS Endurance I'm using on my 7-inch endurance drone. They seem to be missing some torque and when I've found that new low-KV (1600KV is still a lot) EMAX motors, I did not waited long to order. I love RS2205S and RS2306 and hope RS2 will not disappoint me.
What can I say about EMAX RS2 2206 1600KV before installing them on anything? (so far I got only 2, the second pair is on a way)
- They finally changed those plastic boxes to something smaller
- RS2 2206 1600KV look good for sure. Black and Red!
- No bottom cap since, well, you do not really need it after all
- 29g with wires
- 4mm shaft made from titanium (at least they say so)
- Bearings are 8x4x3 if I can measure
- They kept this nice screw in the bottom instead of a c-clip
- Mounting holes spacing has changed! Instead of a standard 16x19mm it is 16x16mm now! Check your frame. The great majority should accept 16x16mm but there might be some rare ones that will not!
- Single wire winding. Looks ok, TBS Endurance has a nicer winding tho!
How will EMAX RS2 2206 1600KV behave in the air driving 7-inch propellers? work? Good, I hope...
