It's getting to that point.

It'd obviously "cog" if the sensor is reading a signal that the motor is going the opposite way. most likely you'd damage the esc running it that way.

I have 3 MMX's 1 Tekin T8 truggy motor, 1 with a HobbyWing 4268 G2, and 1 in my bomber with a HH PP 3500kv, all are extremely smooth.


Have you tried a different radio/receiver? I know i'm crazy but with all of the problems youve been having/troubleshooting im doubting its the esc or motor

I've checked polarity and replaced every electrical component in the truck except the servo. But I ran all tests with the servo unplugged to rule that out.

I spent another hour playing with my two MMX ESCs. Both still make the Tekin ROC412 cog like a mofo. Yet the 35A HobbyKing ESC is still as smooth as butter.

I'm giving Castle a chance to respond to my latest email, but I've already started the process of returning one to Tower where I bought it. I'm looking to replace it with a Tekin RX8 or HobbyWing. I've had tons of luck with HobbyWing so I really like them.

The specs for the RX8 look pretty sweet (gen 2 anyway, I haven't looked at gen 1). Please let us know how you like it if you get one! Also, could you say which HobbyWing you have in mind?

Definitely impressed by your patience with the MMX. Castle told you the MMX + ROC412 work well together? This is the last option I can see, for what it's worth.

The XR8 SCT Pro or XR8 Plus are the two at the top of my list. I'm not sure how they differ at this point.

Yes, Castle told me they have run Tekin motors (didn't specifically mention the ROC412) and they work great with the MMX.

[Thloftus]

Looking forward to this getting worked out for you. Way too much hassle.

I'm flabbergasted , I'm running the cheaper MMP with my Tekin 4x4HD 3000 and zero cogging, buttery smooth......


Hang up and Drive

I set up my MMX + 3500 kV HH puller pro enough to look for cogging; it's installed in bomber, but looks like a mess. I don't see any cogging. I tested climbing my toolbox (similar height to where cogging occurred in your video; stuck inside due to rain). Seemed very smooth to me -- nothing like the cogging in your videos.

I'm powering it with a 40 C 3s Turnigy lipo. Factory default settings for the MMX since I haven't connected Castle link yet. I'm not sure if the firmware is up to date. Also using the HH sensor cable and had the steering servo connected to the receiver. The servo is a HH HV500. I haven't changed the default setting for the Internal BEC.

Bummed that none of the changes you made fixed your problem.

It seems like the MMP and ROC412 and MMX and Holmes motor combos are fine. I haven't found many people running the MMX and ROC412 though.

Yep. Not the best outcome, unfortunately...

I got a strange PM this morning on RCTech. The person, who will remain anonymous by request, claims to be a software engineer at Castle. He stated that my cogging issue is a known glitch in the firmware and that an update should be coming "shortly".

[Rjohn929]

That may be accurate. I know when I first got my Viper VTX8 and tried to run it with a Pro4HD it cogged extremely bad and immediately got really hot. I ran the software update on the ESC and everything was great. Nice and smooth with no more cogging. Hopefully they send that update ASAP. Must be something with the sensors Tekin uses.

Hey that's good to hear! Still sucks, and hopefully "shortly" will not be weeks.

I agree that is great to hear but Castle and "Shortly" are like oil and water.

Question is are you going to wait or return it?

Hopefully it works and that I get it quickly!

Agreed!

Well I may have waited too long. I realized I bought it on September 30th. I have another email into Tower so I'm awaiting a second response to see if I can return it. If not I might be stuck with one MMX.

I did order a Holmes Puller Pro 3500kV motor last night to test with the MMX. The motor won't go unused. It'll either go in my Wraith or my 1/6th scale Jeep project if it doesn't end up in the Bomber.

[calcagno45]

I really like the PP3500 in my Bomber. I was out yesterday hitting wheelies and doing stoppies then slowed down for some technical curb crawling.


If you're still at whit's end with the MMX, shoot me a message and I'll take it off your hands.

[XSRCdesign]

I really think you will be happy with the mmx/ puller pro combo

I'm tempted to try the XL in my bomber

Are you running it on 2S or 3S?

Thanks. I will let you know if I'm looking to get rid of it.

I hope so. But I was thinking I'd be happy with the MMX/ROC412 combo too.

I would have gone with the XL except I believe I read that JRH said it's not as smooth on startup. That would be a detriment when crawling.

[XSRCdesign]

That's true, but I have it, so it's worth trying to see the difference

3s all the time. Plenty of power and as smooth as I can be with my trigger finger and a linear throttle curve. Temps have been staying at the 110-120*F range. I'm impressed.

I'm considering getting a Brood motor as well to try but I don't have another trail/crawler to try it in. All else is go fast. Time to expand.
