Why not run a aevox motor with the sensor built in to it. I don't know if these motors are any good though.

aveox motors are pretty average from what I've heard

Although there doesn't appear to be further information about them, the Feigao website shows a category for sensored brushless motors. Maybe this is worth checking out?
The sensor wire in the picture appears to be similar to the one on the Novak.

Why do so many companies make the motor but no esc for sensored? It is no company that I am aware of that makes a hi cell count sensored esc. I think with the right equipment the sensored could be supreb to the sensorless. It would have smoother start and longer run time with a faster speeds. I could see a 2250 now with a sensor on it. :D

3 wires vs. 8 wires ...

To Dafni:
UE idlers, shimmed tranny, SVD-s all-around (It was my 6*6 Monster E-Maxx)
The last plastic gear snapping teeth upon braking, regular failure. Working on alum. replacement. Spur is a weak link, because metal ones were on 70 and 72 :) with box full of stock 66...

I am working on sensor part... Novak's built-in difficult to reuse.

To Sneeck:

You correct, those pins are pain, it is difficult to remove them (good 13 and 15 tooth 5mm pinions :) do not forget alum. gears...) and easy to loose them. Your solution works!

To Serum:

It is usually Hall sensor, which flip-flop upon magnetic field. You have 3 sensors to complete the circuit.

To Coolhandcountry:

Aveox has good motors, but Kv selection better fit aero then auto. But I used in the past and liked it, 4-poles business …

To Batfish:

I had some discussion with Feigao representative and he told me that sensored motors would be released as soon as they finish testing Feigao sensored controller. That was some time ago, I mentioned about existing Novak and Aveox controllers. At least connector looks familiar :)

General:

I think it would be great to have a controller with sensored and sensoreless capabilities built-in. Ultimate performance of both worlds and combined reliability. (As well as complexity… and vulnerability :) )

P.S. 14-pole sensored outrunner with direct drive :)

Artur,

Are you stripping the output gear in the tranny or the spur gear? If the output gear is stripping on hard brakes, replace the idler gear and you should be ok. Over time, the idlers develop a sharp back side, which cuts the outpur gear on hard brakes. Look at the idlers and see if the back of the teeth are sharp. A single speed also helps a lot.

Or, you could have it programmed with no brakes so this doesnt happen. Mine is this way, but not by choice...

Good point, I will check. Need to take tranny apart anyways. But I will take some pictures first, camera should be back tonight :)

How?

Artur

A rc with no brakes sound like it is going to break something.

Just curious how to...

That's one heavy sensor. ;)

One electrified t-maxx..

its huge!!

Well an rc with no brakes that goes 30 mph. You won't be able to stop it. When you crash at 30 mph it will break something. I was not refering to driveline. I was refering to many other vulnerible parts. That is a cool and neat idea. sensored feigao 7xl.

WHen I got my 18120, it was on boat programming and it has no brakes. Its not bad once I got used to it. My output gears are still going strong. I only trashed one because my Rx pack was dying and It wasn't shifting completely.

I wasn't recommending this, just throwing it out there.

Nice work, I don't see any real disadvantage to sensored as a technology, the products just aren't there yet though (for more than 6 cells anyway). Looks like you really know your stuff, although it is quite a bit of dead weight to be carrying.

Is that a T-Maxx chassis? How hard is it to transplant one onto an Emaxx? I guess the front and rears are mostly the same, its just the tranny and servo's i'm concerned about. I'm on too much of a budget to spend $200 on a chassis but T-Maxx ones are nice and cheap :)
