Bought 3 Arrmas. All 3 were V3, BLX. TYPHON, BIG ROCK, SENTON. NO cogging issues with Typon or Big Rock. Senton cogged badly. If stopped on hill, trying then to start up hill, esc would shut down. I called store where I bought it, they said it's normal. I thought, if normal, why doesn't Typon /Big Rock shut down? I knew something was up.. Simple Fix: I found both Typon/Big Rock pinion were 15T. Senton was 20T. Installed 15T on Senton, problem was fixed. That's all it was. So if cogging is so bad, gear down a little. I enjoy your channel, (like /subscribed) because it's like this video, I thought sensored was THE WAY TO GO. I LEARNED, not always. Thanks

1:51 This!!!!! 👍🤭😂 Love this moment, perfect timing)

Strange how this happened, timing worked out though 😂

Another advantage (or dis-advantage depending on your situation) is the zero RPM cogging under extreme load. The reason I say this is because if you have something bind in your drivetrain (for example like happened to me is a grub screw comes loose on your pinion and gets trapped on the motor mount on a Arrma Typhon) less damage can happen to the car compared to a sensored system that may run even though it is loaded down due to the binding in the drive train.

Interesting perspective Adam.

Very well explained! As usual, timing is everything 😁✌️

You found it!

In short, if you are running a crawler or something else that needs a lot of slow, low end control, go sensored. Anything else, go sensorless.

Also, AM32 loaded ESC can run sensorless motor on crawlers!

Not always. Try sensored hobbywing 2800K on the track or something smaller in 1/10 onroads. Motors are more accurate. Also there you can feel better connection with the driver. Does not exists only bash or crawling :-) There are also hybrid motors which are running in sensored mode on low speed and then switch to sensorless in higher speeds :-)

I can now compare it after some tests. In indoor 1/10 buggy was a changed behavior without sensored cable just a little bit. 1/10 onroad, there is still need for me to have sensored for precious curves and also for accurate breaks, then accelerate in for example with my xray X-1 formula and Hobbywing 21,5T But i tested in 1/8 Serpent SRX8e PRO with XR8 ESC and hobbywing 2600K(suited for onroad but im using it in buggy) and there was no difference in sensored/sensorless mode on the dusty dirt track. So it is up to everyone. Im just writted my feelings from the own tests. Im just hobby driver. The more important hardware for me is a good fast radio or strong and fast servo. Can live without sensors on 1/8 scale Buggy/Truggy :-) I have not any crawlers, but when i have some, i will definitely want there sensored combo in all scales of the truck. Because there are so slow speed requires precious handling.

Great explanation once again. Thanks

Glad you liked it!

The Main advantage that sensored has over sensorless - the cogging at low RPM, can be overcome with a few different methods to glean the back-emf information from the windings alone. One promising example is High-Frequency Injection (HFI), and the startup sequence can be altered from punching at 1 phase at a time, to full on sinewave 3-phase commutation with some sort of ramp-up time. Sure it might be inefficient to run it in these states but the intent is to kick it into the back-emf-sensing realm of the esc as strongly as possible.

I'm pretty senseless, but this video makes sense to me. 😉

Always a wealth of info thanks

Thanks for this video, it's cleaned a grey area of opinions for me. Question. Not all my Boats are bolistic. I have some that are to be slow. (Tug boats/warships). How can i get brushless to go slow enough for tugs. Its not quite right to see the Rotterdam and Imara planing. Is there any way i can go brushless in these ships or am i stook with brushed motors. Thanks for any help.

Yes, go for a low Kv larger Outrunner style motor. These motors will rotate at very slow speeds and do not need to be sensored either.

Interesting. I know that you can adjust the timing on the motor and also you can program the ESC for the motor timing. Could you share with us how to program the ESC to have variable timing and if this is with just specific ESCs? Any information you can share would be greatly appreciated. Thanks for the video.

Say I go "sensorless", Can you get the RPM from the ESC without a sensor? i.e the ESC is sending pulses at a particular rate to the motor.... Perhaps it depends upon what ESC is in use? Whether it supports bi-directional dShot?

Getting Rpm from the esc is not determined by sensored vs sensorless.

Why do mod class racers all run sensored motors?

Does changing the spur and pion gear affect the internal pion gear

Are you referring to the differential gearing? No it does not effect this.
