GEPRC GR1206 6000kv motor thrust test
#1
I got myself some GEPRC GR1206 6000kv motors for my 3” DRC Legit build, as usual, curiosity led me to push one of them first on the thrust test stand.

I got them from Banggood.

Here we go…

Manufacturer specs:
6000KV
No.of Cells(Lipo): 2~4S (Me: 3S on this kv)
Max Current(180S): 15A (Me: it gets hot pretty fast on 15A+)
N52H arc magnets (Me: not really arced...)
Weight: 8.3g

For 6000KV - 2.5~3 inch propeller and 3S batteries are recommended.

Package includes screws for 2mm and 3mm frame arms and a set for propeller mounting:
4 x M2*4 screws
4 x M2*5 screws
4 x M2*7 screws

Quality is OK, motors rotate smoothly, not too notchy. I will put that out of the way - specs state that magnets are arced… well, that is usually hard to judge on smallest motors, but we can be certain that it is not the point here. Magnets are definitely flat:

(you can see the machining here. Note that this bell is tiny!)

Magnets are placed on a small lip, they will certainly not fall out. That is my first micro motor that has this feature.

Thrust test:

I tested this motor on a selection of 2-3” propellers:
AVAN Micro 2”
DAL Q2035C
Gemfan 2540-3
AVAN Rush (2.5”)
KingKong/LDARC 2840 triblade
Gemfan 3025
AVAN Mini 3”

Data taken with RCBenchmark 1520 thrust stand

As usual, static tests show that the Gemfan 3025 is the efficiency king. 3” AVAN prop made the motor really hot (and smelly…).
I tried to fly on those damned 3” AVANs, motors were hot even after a 30s hover. I am not testing this prop anymore as it always seems to push the limits.

I chose to fly on the KK props right now as I’ve seen a lot of positive reactions to them and they felt really nice. I’m curious about how the AVAN Rush feel - unfortunately it is way too windy here to test anything now Sad

In general, when I compare this motor against the Racerstar 1108, it is giving ~twice as much thrust, pulling ~twice as much amps but also costs ~twice as much USD. Everything checks out Wink

Enjoy some photos:

Find me on Youtube and Instagram. I currently fly: DRC Aura, NOX5R, Minimalist 112 and drive a scrap RC car

I'm not in the market for a micro build, but just wanted to applaud the effort and detail in this post!

I use their 2306 motors and they've been solid performers.
