Scorpion MII 2204 2700kv
The new Scorpion MII 2204 is the first 2700kv motor, that I have tested on my thrust stand. If you haven’t read my review of the Scorpion 2300kv motor, that I published few days ago, do it now. Everything that I said about it, is true for the 2700kv version. The only single difference between both motors is the weight: the 2204 2700kv weighs 0.6g more.
I have tested the motor with the following ESCs to ensure the maximum possible thrust: KISS24A, LittleBee 20A Pro and the XRotor 20A. Both LittleBee 20A Pro and the XRotor performed better than the KISS24A. In the range of 1400µs – 1800µs the motor provided more thrust with the LittleBee ESC. The maximum thrust of 1073g was achieved with the XRotor 20A. For these tests I have used a HQ5045 prop and 4S LiPo battery.
I also have done a test on 3S with the same 5” propeller. This data could be mainly useful for new pilots, that don’t need a very fast quad at the beginning.

The Scorpion MII 2204 2700kv is a great choice for some smaller 180mm quads too. That is why I have done a test on 4S with a KingKong 4045 propeller.

Summary: I like the look and the build quality of the MII 2204 2700kv motor. If you are planning to build a small FPV quad, you can definitely choose this one. So far I am very happy with it and will build my next FPV quad using these motors. You can find the set of 2 motors on the official webpage of Scorpion.
Please do not hesitate to leave me a comment if you have any questions or want to share your experience with this motor.
Did you try them with triblade¿?
Hey Eloy, no. Still have no triblades. Noted on the To-Do list 🙂 Best, Sergey
Hi Eloy, sorry for my bad English .I builded a nighthawk 200 with these motors, it flies pretty nice, but after like 2m of flying motors or esc (i dunno) stop suddently, i think it could be too much amp drawing but i can’t check it to verificate. After the quad fall down, it can fly again nice as before for a little time and then occasionally fall down again, i think it happens when i fly more aggressive. I have this problem just with 4s lipo with the 3s everything is fine, flip and stuff.
My rig is:
naze32 rev5 cleanflight
4s 1400 65c
4.5 2blade props
That problem won’t happen on 3s 1300 45-90c
Maybe you or some one else with those motors have the same problem and you figured out how to fix it in order to fly a full 4s battery without trouble.
ehm sorry Sergey i thought Eloy made this, keep the good work up!
Hey Francesco, you should have a bad solder connection. I have experienced similar problems in the past and it was because of bad soldering. Solder everything again. Best, Sergey
Hi Sergey, thanks for reply. I don’t think its a matter of soldering, otherwise the problem should be present also when i fly on 3s lipo, anyway i’m going to triple check again all my soldering,
I would like to share with you a blackbox of that problem and also my blheli suite setting, but i don’t know how to share those things on this thread.
I opened a thread of this on another site with everything http://www.rcgroups.com/forums/showthread.php?t=2757865#post35948019, if you can take a look.
Can i set low ESR cap with blheli suite? i can’t find anything about it, how can i do it?
thanks for your time, best of luck!
A cap can only be soldered to the ESC. It is an electronic component – capacitor 🙂 The problem could be because of the ESC, but in general all current ESCs work fine on 4s even without an extra capacitor. Re-do the soldering again at first place. Best, Sergey
Unfortunately i dont have a spare esc to try it, i’m going to redo soldering right now. I still can’t figure out why it flies perfect on 3s and why it doesn’t on 4s.
I will update after resoldering
I noticed on BlackBox motor #3 was doing strange things, so it could be a bad solder on motor #3 or a bad esc/motor. I swapped just the motor because i dont have a spare esc and resolder everything, and tadaahh!!!! GREAT SUCCESS
Seems fixed! i managed to finish my first 4s lipo pack!! I’m super excited.
Those motor are crazy, sounds like F1, and punch on throttle so high, i’m loving it.
Do you think i could try bigger props with my rig like 5030 or even 5045 or even 3blade?
Big Thanks to you Sergey, you just made my day!
Best of luck
Great! I am using these on one of my quads right now with these KingKong 5040 props on 4S without a problem. Super fast 🙂 Best wishes
Nice to know, i was super worried about amp drawing, those motors also suck like a slut, i will try bigger props! I can’t stop thank you again and again 😉 first 4s setup here freaking awesome!
