LT-10s in a e-revo - RC-Monster Forums

hoovhartid · 11.24.2008, 02:10 PM

The KB45 is new. I went and looked at the pics (you made me wonder) and it does look funky in the pics. It actually looks normal in person. But the motor was new in the pics. From the box to the truck I got it the same week as the ESC. I have only run it on the LT-10s. The temps have never seen over 170 (168).

Thats not to say the motor is perfect....after all, we are talking about a $50 motor.

Everyone else that saw it run, and tried it out, said they thought it ran great. Everyone kept asking why I wanted to make it go slower...

I think its just me. I was able to get the MMM/Neu to crawl at very slow speeds. Which begs the questions...."why?" and "How often did you do this?"
To which I answer..."um ...almost never"

Everyone at the track seemed to love how it ran. The LT-10s and KB45 in the e-revo is a POWERHOUSE. I have never had a truck go from street to grass and not slowdown at least a little....but this went through grass like it wasnt there.

The ESC temps were always very low too. The highest temps were recorded on the caps hanging off the end. The most I could get them to go to was 130F. .....and that was getting the motor to 168. Batteries were never much above ambiant (90F)

Over all, when running normal, the ESC is great. I was just trying to soften the slow speeds a bit.

It's cool. I just got concerned a bit as I've seen a few motors look like that after they overheat. Lincpimp will be trying my 100A sensored ESC in his crawler and should be posting something real soon

. If you need really low speed capabilities a sensored set up is your best bet. A sensorless has to spin the motor to sense where the rotor is and in some cases they start a 500rpm to get some BEMF.

thats what I was thinking. I am interested in the 200A sensored. I'll be watching that one

One is being tested by snellemin and a 100A is being tested by lincpimp in his crawler.

I'm having a blast with mine as well. Zooming over grass is great. Snapped two flm axles and broke a dogbone within a minute yesterday. ESC temps stay at ambient with the fan installed.

I made a very simple esc mount for lutach's esc. I mounted it over the rear shocks, using an existing screw hole on the rear body post, and some spacers and longer screws on the shock mount to stay clear of the shocks. I'll secure the esc with some double sided tape or velcro.

That looks nice. You know you've also made a brace that will make your chassis a bit stronger too. Do one for the front as well.

lutach,

do you think the esc is too close to the receiver?
I could also place the receiver where de 2nd servo used to be.

making the front brace wouldn't be as staightforward as the rear brace. I was just lucky that the rear body mount has a free screw hole.

Shouldn't be a problem. My receiver is basically the same distance as yours in my MBX5T, but mine is in the open and yours is in the case.

great idea drkdgglr so i made something similar with lexan. Build can be found here. :)
