Sensored Outrunner motors- Revolver S

I'm pretty sure I wasn't using any timing advance as it was never recommended on the 412. I'll double check everything tonight. I'll try and take a vid as well.

Okay, so I did some more testing last night and made sure the timing was set to zero. With the sensor wire connected at all times, I put the esc into dual mode and tried the motor out in both directions. There was no problems. It ran as expected and did not shutter or surge. Everything still felt cool to the touch. However, when I kept the motor at low speed where in think the sensor is still active. Things got warm.

I went back in and programmed the esc to be in sensored mode only and the symptoms came back. When the motor got up to speed at full throttle, it could not maintain a constant rpm and would waver. One new behavior occurred, while speeding up to full throttle, the motor would jerk to a stop and then continue to spinning where it left off. This only occurred for a split second, but it was enough to torque the entire transmission housing. Once again, esc and motor got warm.

So these symptoms would suggest a sensor board issue. Or maybe the sensors are slightly out of position.

Any thoughts?

I tried that before as well and noted it in a previous post. Ran fine, no heat increase...

Timing on the esc was always set to zero on all tests.

My bad...

[JohnRobHolmes]

Timing board issues normally present themselves in one direction, but not the other. It is possible that the RS wants to run with a bit more timing, have you tried bumping the timing up a bit to see if it changes the operation? We have had no issues with the RS here, but honestly I don't even know what firmware we are running as I don't like the Tekin USB process.

[cytogen]

I'll do the tests again and make a video of it. After this, I'll most likely send it back for you to check it out. I don't think my ESC, motor wires and the motor itself should be getting as warm as it should with under a minute worth of testing in sensor mode. I don't want to blow my RSpro.

I'm running the most recent code on RSpro, 223.

Anyone else out there running a RSPro on these motors?

I will be running an rs pro as soon as my motor comes in. Will also be mindful of firmware revision. Wonder if rolling back to an earlier version (a la castle's stuff) would help?

Okay, here is a vid of the testing;

Hmmm, that seems different from the problem I had previously mentioned; mine occured only in one direction and didn't sputter like that.

Previously I had it installed on my Gmade R1 and I guess the "surging" was not as apparent as there was a lot more momentum from the rig to buffer it. But with it in the xr10 axle, there no weight at all which make it very apparent.

Got mine in today, definitely don't do any advanced timing. It was acting weird before I knew the settings. Working well now with an rs pro on the older firmware (a quick look only showed 2 versions, but admittedly never saw the software till today). It was also recommended to me to double check that the esc took the settings, apparently sometimes the esc's won't save them.

[Postclanker]

I have to admit, I've never heard a motor sound like that before. Sounded like it was turbo charged. Had quite the "scream" to it at high rpm...I liked it.
I learned a long time ago to save the Tekin settings twice....

[Meatwad]

The scorpions I ran in the past sounded funny too, which I think part of it is just being outrunners.

hi John, Holmes Revolver S TorqueMonster 550 is made only 1500 kv version or do you make custom wind?
thanks

Hello John,would the Revolver S torquemaster be ok suited to be around muck and water? Mainly the occasional streams/creeks etc. ill admit I can be a little rough on motors sometimes. the build I'm doing now is not a mud bogger it's a trail truck but it will see mud and water.

You will fry your controller trying to bury the throttle over and over when things aren't working right. Send it our way if you can't narrow down the culprit, will will fix it or replace it if needed.

Currently we only offer the 1500kv. It is the fastest possible in the 550 size without reducing the magnet count and sacrificing startup smoothness. What KV do you need?

We waterproof the sensor board and the coils are resin sealed. You can run them in the water if you want, but bearings will rust and you may dislodge a magnet if something gets sucked into it. Like any motor ran in water, you should either care for it after every outing or just buy a super cheap brushed motor.

i 'm happy owner of revolver s 540 ( in italy we are only 2 people run it), John this motor is awesome, smooth smooth start up and a terrible amount of torque, we only need a little bit more Kv ( 540 or 550 is the same if you can make it) , i say 2500-2600 kv..
thanks John

We are maxxed out on speed for the 12 slot 14 mag design, they are 1.75 turns. Any faster and it won't run. We are testing a 3000kv 12 slot 8 mag, startup hasn't been very good on previous tries but we are tweaking and testing.

We are working on a higher speed version with a different stator, however. It is a bit smaller in diameter and the motor will handle 60k rpm. It is extremely smooth starting and can have a kv from 1000 to 6000. We are shooting for a summer release. It will round out the sensored outrunners. It is a four ounce destroyer of 4 pole motors, a real power house!

This sounds good John!!! Keep me posted
For now i tried revolver s on 3s with 44-24 spur -pinion, 1: 3.75 tranny ( PS tranny) 43/13 HD and 4.75" tall tires, RX8 gen2 and Nvsion 4200 3s 60c with rcplus 180amp ; i have also to try thunder power 3300 70c 4s and i think will be much more terrible
I will post a video with gopro 3 as soon as the weather will be better
Thanks John and sign me for your next awesome motor!

is there any way to get a 900-1000kv outrunner made from you guys? I know you offered one a few years ago but it's no longer available.
