I have been using the R5 motors for a while and like them a lot. After hearing many complaints about the bearings on those motors, I am super excited about the release of the Brotherhobby R6 2306 motors which better durability.

What’s New in the R6 2306 Motor
The first thing you are going to notice in the R6 motors is new chameleon color, but they are not too different from the R5. They have exactly the same magnets, design and even weight, however there are some improvements.
The best change is the bigger, more robust bearing. In the R5 we have a 8x3x4mm, and in the R6 we have 9x4x4mm, which is 1mm wider on the external diameter as well as 1mm taller. Theoretically smaller bearings might be smoother? I cannot wait to find out how the larger bearings have an impact on that aspect.
Another issues I’ve encountered with the R5 is loose props. Sometimes I git a small branch and the prop nut just got loose. This is mainly due to the lack of grip between prop nut and motor bell. It’s good to know that there is now much better propeller grip on the top of motor bell.
A few interesting features of the R6 that are different from motors of other brands:
low profile shaft and prop nut, to reduce weight.
Specifications:
- Mounting: 19x16mm
- Single-stranded winding
- Shaft is retained by a screw rather than C-Clip
- Rated for 4S – 5S
- Wires: 15cm 20AWG
- Weight: 31.6g with 15cm wires, 29g with 4cm wires
- It comes with 4x 6mm screws
Awesome motors, really like them. Here is my video featuring them:

Hi oscar,
Have you find some time to test this motors ?
I bought this to, and with prop in 48 or 45, i kill all lipo i test ….
I find it too regular in speed, not smooth … but i’am a rookie.
Waiting for your review !
Best regards

It’s been tested and video posted on my Youtube Channel which I’ve just added to the post :)
Am I the only one that have loose props on these? The shaft diameter seems to be a bit thinner than usual and the props can wiggle a bit when the nut is loose. I think that affect a LOT the balancing since I can’t be sure if the prop is prefectly centered on the motor. I tried Racekraft and Dal props I still see this happen. I’ll try HQprops soon.
I had loose props on the R5, but not the R6 as they’ve fixed that. Maybe try tighten it a bit more :)
I had the same issue until I replaced the nuts that came with the motor. They don’t look as cool as stock but performance outweighs cosmetics in my book. I haven’t had a problem since.
