LRP 21.5 Brushless Crawler Motor and ESC Review

So, after going through an enormous amount of pain and suffering trying to find the right motor combination for the Losi Comp Crawler, I stumbled onto a winning combination. I didn’t know when purchasing this set that it was affiliated with Team Associated or it would’ve made the purchase less painful at a total of $220. It turns out that the setup is top notch – as one would expect from Team Associated.

Anyway, the hand wound Crawler 21.5 Brushless motor features sensor/sensorless operation and neodymium magnets. It has a built-in Hill brake, but that isn’t needed with the worm gears in the Losi Comp Crawler, but I’d like it in my Axial AX10. The ESC also has no reverse delay and 4 unique crawler throttle profiles.

Driving the LRP Brushless Motor

Wow. I have not run brushless in a crawler before. I had that same ‘special moment’ when I powered it up as when I threw the Monster Max in my eRevo. I don’t know if it has more to do with the out-of-the-box quality of the the Losi or the LRP combination, but I REALLY like this setup.

I’m reading a lot of people in the crawler community mentioning “wheel speed” lately. It is nice to have a little bit of “blast” on reserve to power up tough sections when you need it, but I also like driving super slow. The LRP setup is great for both. It easily packs more punch with a 6 cell NimH battery than a comparable Novak 55 turn brushed setup on Lipo.

LRP Slow Speed Crawling

Where things really get interesting is at the super slow end. This thing is buttery smooth…unbelievably silky smooth…..super slow….(words can’t describe) My Axial has a Mamba Max with the Novak 55t and I can almost feel the revolutions of the motor if you know what I mean (not literally, but that “chug chug chug” feeling when going slow). The LRP setup is just totally smooth – unbelievable low end. You become intimately intertwined with the Crawler as it responds to the trigger. Inching up something is fun. It’s hard to describe until you do it.

Four thumbs up for the LRP setup – well worth the money!
