~1.3 Ohm
Installed parallel to OEM X4 and 720 Hollows from BG so a mix of three different motors running fine.
Just got the second batch I reordered for my new H436 Hybride.

We can rebuild it!

1.3Ohm? Wow that's low, the "hollow cup" are 1.8Ohm and the stock are 2.3Ohms, so you have 3 different motor resistances and it flies fine? That's good to know, I'll order some more of them then, my first pair arrived a day or two back.

One of my front rotors came off mid-flight, and I caught it on video.

Hubsan x4 prop came off mid-flight (0 min 46 sec)

I never finish anyth
I had one prop that came off anytime the throttle went above 75%. I was at work and dint have any spares on me so I made it into a game.... what can I do without going over 75%

My props will pop off only when hit something/crashing

New props came today and now X-4 is back the way it was. I like black and white props.

x2. I even ordered some Black/White for my 929.

I used some white canopy glue on the bottom of each prop...doesn't come off in flight or crash, but will come off with a little force for replacement...them little buggers are hard to find.....get some neighborhood kids into your yard a offer a dollar or two for the kid who finds it.

Just want to share my hubsan TX settings to easily achieve banking turns and 8 figures, indoor with expert mode. Set all settings at 100% except the RUDDER at 50%. Simply amazing how this beast behave. Will post a video soon ;O)

I've noticed that the X4 controllers have a less gerbilly version. This is after confirming the rates are set at default. Some controllers seems smoother while others are super twitchy. This is using the different controllers on the same quad.

Hi MO,
Are you talking about the X4 Tx or the flight controllers? Are there version numbers associated with your observations?
Cheers,
Jim

I thought someone mentioned earlier that you have to measure resistance while turning the motor, and take the average Ohm reading. Not doing that could explain these very different readings.

Hi J,
That is true. Also older motors will tend to have that slight amount of more resistance due to carbon build-up on these tiny brushes. So you need to do resistance comparisons with new motors. The slower and poorer performing coreless motors micro Kv motors(~10,000 or less Kv) generally have resistance in the 3.0 or greater range. The motors with >20,000Kv usually have ~2.0 Ohm.
Cheers,
Jim
