I have a hobby wing 10bl60 sensorless esc. I got what I thought was a matching motor, but I didn't do enough homework, so I'm in the market for another motor. So now I am looking at a hobby wing ezrun, either 3660 or 3652. The 3660 is for 1/10th SCT, the 3652 is just 1/10. Will they both work wit my esc? Which one is preferred for a relatively heavy 1/10th basher?

If they will work, what kv should I be looking at? They are available in 3200, 4k, 4600.

The 3652 is a fair amount cheaper, but I don't want to under power the truck. I'm also not looking for blistering speeds. Mainly good low end torque and moderate top speed.

I would also takes recommendations from other manufacturers that will work with my setup.

What kind of vehicle are we talking about? The larger of the two motors would be better. The 3660. Still, these are relatively small ish motors. Not that they aren't good. For their size they are impressive. Perfect for a 1/10 2wd stadium truck. I actually used one in a small ish 4wd truggy, the HoBao Hyper TT, and it did fine, although I also added a fan. I replaced it with a full size Castle 4-pole motor and was happier with that. Hobbywing makes good products. Let us know what vehicle we're talking about and we can advise you better. But for a "relatively heavy basher", I would suggest one of their larger motors in the 540-size.

It's a redcat blackout xte. I had a tmaxx way back and this one feels heavier, definitely heavier than the stampede 4x4 I compared at the store. But I can't find a published weight for it.

I tried to get this initially one but I couldn't find it anywhere from a reputable source. And this is the same size I believe, just a lower end model of the one I listed.

Definitely want to throw something in there with a longer can for more torque. There are oodles of 550/3656 sized motors out there that would fit the bill, but the price for above ^^^ HobbyWing motor is pretty darn good.

Motor l linked is directly from HobbyWing.

Of course, HobbyPatrz is out of stock, but, something like this....

So obviously I'm new to electric. So 550 and 3656 are the same size? What about 3650 vs 3656? I'm having a hard time with the numbers, acronyms, dimensions and can't tell what's a measurement and what's just a model number.

I currently have a sensored 3650. That's my problem, I thought I could use sensorless esc/sensored motor but was wrong. But if you a 3656 is physically longer, the 3650 barely fits. Is that what it means?

So would I need the while kit? Or would just the motor work wit my existing esc?

It also looks like the 3652 and 3660 have different input shafts. Is that also something I need to worry about?

Yes. 540 sized motors are sometimes shown as a dimensional number ...3650 = 36 x 50mm. 550 sized motors usually start with sizes around 3656 = 36x 56mm.

It seems to me I went around this subject before on the same platform in the Redcat section. A little "lip" on the chassis needs to be Dremeled to fit longer motor cans?

Good info. I did poke around the redcat specific forum, but they are not exactly the most popular brand. Although I really not sure why. I haven't had mine all the long, but the parts seem durable and substantial. The hardware is all hex. My tmaxx of ten years ago and my teton of last year can't say that. It does seem a little underpowered, hence the upgrade, but had I done it right it would have been the same price as a comparable stock Traxxas with all upgrades electronics.

Don't feel bad, mate. There are a lot of niggly little details like that in this hobby. You get used to it. A sensored ESC can run a sensorless motor, but a sensorless ESC cannot run a sensored motor. The ESC needs to be able to detect where the rotor is in its rotation in order to fire the stator coils with the right timing to turn the rotor. A sensored motor has a sensor built into it and a wire harness going to the ESC for this purpose. This method gives you a smoother throttle feel at low RPM compared to a sensorless system. In a sensorless system, the ESC uses the feedback it sees on the motor wires (the back-voltage) to sense the rotor position and a "start up routine" in the firmware to get the motor turning, then switches to run mode, all in milliseconds. How smooth that start up routine is depends on the manufacturer's firmware.

Thanks for the info. I normally do more research, but s*** happens. Honestly though, once it did get going after the 2-3 second delay, the power isn't quite what I was expecting. So I'll be looking for more power with the "right" motor this time.

So on that note, the 3660 has a different input shaft size, I have verified that. So is that as easy as getting another pinion in the same tooth count to compensate? Then I just have to make sure the motor will physically fit lengthwise in the space I have.

I see where the length of the can could be an issue now. Earlier I said about using Dremel tool. That was on another Redcat/Exceed/HSP chassis.

Shaft sizes will be 5mm or 3mm ( sometimes called 1/8 ) .
The xte gear pitch is Mod .8 which is compatible with 32P .

This is exactly what I needed. I think then I will measure to see if the length of the 3660 fits and get a new pinion to make it work. Sounds like that should give me good amount of power.

So if anyone is still following this, what kv should I go with? 3400, 4000, or 4600?

Redcat use a 3800 in the pro model . If you are using a 2S battery , i would try the 4000 .
