Motor database (Added the Avroto M2814-11S)

Motor database from the motors I have.
I measured them at 100g/200g/300g/400g/Max trust

I use the Unilog as test tool,



The way I measurer the trust,

One more time the Keda A20-22L with a 11x4.7 SF prop

One more time the Keda A20-28M with a GF 10x4.5 prop much better than the Gaui prop!!



Keda A20-50S (1088KV) with 8x4.5 Gaui prop





One more time the Keda A20-50S with a GF 10x4.5 prop

That is a very kick ass motor.
But since you write in English in the forum, is it too much to ask to have the graphs in English too? ~

I do not know how to translate Dutch lines into English lines

Spannung = Volt
Strom = Amp
Leistung = Watts
Drehzahl = RPM

Holco, great job! This is a very interesting practic test! Have you ever think in make a test with Rctimer motors like 2836, 2830... Im waiting an answer from kedamodels to buy some 22-20l, but they dont say nothing at the moment and maybe i buy some rctimer motors in order to try them.
Im thinking in make 2 quads. One small(30cm M2M) with 20-50s and one medium(50cm M2) with 20-22l.
Whats you opinion at the time to choose alternative motors for this measures?

Hi xforus,

Every motor that I have tested and put in the database I do actually have or had 5x > 7x time's, for me it is to expensive to test every single motor that's look interesting, bud if you send me one with the prop you like to use I will test it for you and put the results in this database.

For now I love the Keda motors in the low price category bud for your small quad I recommend you the Turnigy 2209 26turn (Keda KD2209/26) (1130kv) with the 8x4.5 Gaui prop's

I ordered m3 rubber dampers for the Avroto M2814 motors assuming that it will cancel some vibes at the source, the outcome confuses me

The two test's where with exactly the same trottle setting (max endpoint) and tuned at 670g lift


The dampers,


Left is with dampers right without them,
Avroto Motor dampers (0 min 20 sec)

To have a true picture of the vibrations you need to see both frequency and amplitude. I don't know what that number connotes...I'm guessing amplitude. It's likely an increase in a lower frequency possibly due to resonance. I'm betting most high freq. vobrations were removed. Try doing a mount with half rubber mounts and half mounts secured solidly. or better yet 3 and 1. Good luck
