Anyone running sensorless brushless?

[ik632]

I got an XR10 for xmas and I'm excited to start the kit. I plan to reuse some stuff I already have though and wanted to get some feedback.

This applies to MOA so I figured I'd put it in electronics rather than XR10 space.

I currently have the following:
2 x Sidewinder SCT ESC (one in a Stampede 4x4 and one in a MERV)
1 x Axial AX-2 (in AX10 RTC)
1 x Axial 55t (in AX10 RTC)

On the way is a Speed Passion Cralwer Master crawler motor 1000kv which happens to be sensored but I was planning on running without sensor.

So, the question is:

1. Do I buy another Sidewinder SCT and pull the ESC out of the Stampede (it's going to be sold anyway) and then run two brushless crawler motors?
2. Do I get another AX-2 and 55t motor and pull them out of the AX10 and then stick the Sidewinder/Speed Passion in the AX10?
3. Do I get two 35t motors (not sure which one at this point) and run them with the Sidewinders?

I have a FS-GT3B which I'm going to hack to do dual ESC mixing so I definitely want two ESC's. I'm just stuck at which I'll be happier with. I don't plan to compete with the rig, mostly will use it for driving with my son when we go to the park and climb on the rocks. I do want it capable so if we do go and meet up with local crawler guys I don't want to be laughed at for putting together a bad setup.

If my son really takes to it we may go and try and compete a little so I'd like to be capable of that in whichever class the XR10 falls into.

i would definitely not run 2 sensorless motors in an xr10 or any moa crawler. just running 2 brushed motors will be cheaper and be much smoother for low speed control. if set on using the sidewinder sct, i would get another one of them and set both to brushed mode and for 3s lipo go try a pair of 45t motors and if only 2s lipo try 35t motors

The XR-10 would fall under the "2.2 comp rig" rules. It would have:

single or dual motors and/or ESC's.
Max of 2.2" diameter rims
NO rear steer
Max of 12.5" wheelbase

There are other rules, but those are the basics.

Get two 35t-45t motors and run them with the Sidewinders.

I'm currently running brood 40t's and micro pros on 3S.
I've been real happy with this combo

I run a sensorless brushless setup, in my short course truck. You will be very disappointed with it in a moa crawler.

Invest in some nice brushed motors and a decent esc. BRXL FXR are both nice.

Brood and Holmes both make some of the best brushed crawler motors. I run Brood in my 2.2 comp truck and I am very happy with them.

Are the sidewinders missing something that the Tekin's have? I know the Tekin is super small and light. I'd be ok with using what I have to start out. Thanks for the advice on not using the brushless sensorless motor. I already have one in my Stampede 4x4 (the 3800kv Castle motor) and I don't like how it doesn't go slow. I was hoping the lower KV motor was better suited to crawling.

For now I'll stick with the SCT's and pick up some high turn brushed motors.
