EMAX RS2 2206 1600KV motors hands on

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)

  1. They finally changed those plastic boxes to something smaller
  2. RS2 2206 1600KV look good for sure. Black and Red!
  3. No bottom cap since, well, you do not really need it after all
  4. 29g with wires
  5. 4mm shaft made from titanium (at least they say so)
  6. Bearings are 8x4x3 if I can measure
  7. They kept this nice screw in the bottom instead of a c-clip
  8. 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!
  9. 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…

  1. Nice videos and build! I’m planning a 7 inch build too so I’m wondering what kind of flight times did you get and what battery mah did you use?

    Would you recommend these emax motors for a efficient build? I’m thinking of Garila 2507 1500kv but can’t decide!


    1. S800 is not a very efficient wing. I’m flying this motor on 4S Li-ion 3450mAh with APC 7x4E and I get ~35 min while averaging 50 km/h. Efficiency <100 mAh/km.

  2. Where is the update? Did these 2206 1600kv RSii perform as good and efficient as the 2206 1450kv TBS Endurance motors without getting hot/burning out on 6s 7″? Nowhere stocks the RSii 1600kv motors only 1700kv now. Will 100kv make much difference?
