New RCTimer motors. HP series. The good and the Bad

Couple weeks ago rctimer was down for a few days and it came back up and had new motors.

I was shopping around for popular 2830-8 1300KV outrunners,
when I came across similar motor, but with a different name. HP2812-1300KV , specs are pretty much identical, but this one is advertised to have higher performance and "sale" price was very tempting. I ordered 4 for an Armatan style quad to use with 8x4 props.
Previously I had turnigy 2826-2200kv motors on it, and it was a bad fit, SF props slowed it down, but I was wasting prescious mAh's..
In case anyone is curious - my quad has 6" arms, AUW is 860g and I use 3s 2200mah 45c lipo and 30a esc

Took it for a flight today , first impression was great. Nice and smooth, plenty of power and speed for 3D flying.
Bearings were indeed smooth compared to previous rctimer models.
Motor mount and prop adapters were made of better materials, and didn't feel like cheese. If you've ever used older rctimer stuff, you know that those mounts are as soft as tin can.
Wires are longer and thinner than your typical brushless outrunner in this class. Also more flexible.
All in all it seemed like a solid product, and for $13 each, I couldn't be happier.


However fun was over when one of the motors came apart after a few flights. Luckily I was ~20-30ft up in the air and was flying on top of grass. It looks like the e-clip either came off, or broke off and released the shaft. I was lucky enough to get away with as little damage as bent arm, which I can fix, but I'll be very carefully with these motors from now on.
However I'd like to believe it's just a single case and wont happen again. I was always very happy with rctimer motors and even after trashing them for a while, they still held together and performed well.

I'll try to find another e-clip and will take it for a flight tomorrow morning, and will report back.

Curious to hear others opinions on these motors, and if anyone else got them. Im thinking about buying some more before flash discount ends.

Other than failed clip (which may or may not have been my fault) they run reall smooth. I'm considering getting another set before sale ends.

so far alright, even thought one of them is packing some serious dirt at the moment I haven't repaired after last crash in the video

the thing is that we're not supposed to need those, because it's not just a clip we lose, it's an aircraft that is in potential danger. For me personally it's just a pain in the ass to drill holes in new aluminum tube and screw everything in once again.

actually these prop adapters and mounts seem to be sturdier than other rctimer stuff, you can't bend them with your fingers. At least not as easy. And also I got used to them, maybe not the most optimal solution but for sport flying it's enough.

Are the wires the same thin gauge stuff they used on the purple morors?

they are thinner than on purple motors, however they seem to be different material. Purple ones had large lose wire sleeve, and it would always break. Also those wires were a pain in the rear to solder in case you broke it or wanted to extend it.
HP stuff has more flexible thinner wire, with a nicely fitted sleeve whch is made of much better silicone rubber

If I remember correctly NTM wires were fairly thick, short and not flexible at all. Also it might be just my experience, but NTMs felt heavy and too power hungry compared to other motors in same class.

Today I had a problem with one of the six HP 2826 motors (3548 with blue bell) I purchased from UAVobjects. I found that the small worm screw that holds the bell on the motor shaft was loose allowing the bell to rotate faster than the motor shaft, You can imagine what happened. Good thing I was only 2 feet off the ground when it tipped sideways and fell. 3 minute before that I had it a good 12 feet in the air, and was going to raise up to tree top level, but heard one motors RPM going high than the rest and my hex seemed a little unstable so I kept it low to the ground.

So quality control is an issue with this and maybe other Rctimer motors. I must admit up until then, the motors flew flawlessly and had lots of power. I could hover at 40 to 45% throttle! However if the motor shaft and bell become loosened from one another that is a nasty accident waiting to happen.
