Default Review of Holmes Hobbies CrawlMaster 540 (16t)

I installed Holmes Hobbies CrawlMaster 540 (16t) in my XR10. These motors exceeded my expectation in every way.

The 16t Armature on a 5 slotted motor performance similar to a 33t 3 slotted.

My set-up;
- Max Amps 430Mah 3 cell
- Dual FXRs
- CC BEC
- Futaba 4PK
- Hitec 7950

Initially I installed them with 13t pinions and found that I had more than enough speed, so I went to 12t. The drag brake is as good as it was with the Holmes Pro Motors. The startup was as good as a Holmes Puller motor, maybe even a little better. The start speed is the slowest most controllable I have ever had in any crawler. A Novak sensored Brushless was close, but these are better under load. The amp draw appears to be slightly lower than a 35t, my packs did not get as hot and no loss in performance over a 5 min course (with tiny 430 Mah batteries).

These motors feature 5 slotted armatures and stand up brushes, this is not a slight tweak, and this is a giant leap forward. This motor is my new go to motor. I feel it out performs everything else I have had by a significant margin.

I have two in my practice truck and have already asked for two more for my comp truck.

Here is a quote from Holmes that I agree with 100%.

'One cannot build a finer or more precise armature!'


Thank you John.








The Red Motor is the 16t 5 slotted, the Black Motor is a 3 slotted 35t, exactly the same size.

I saw these in action today and they are very impressive. Now I'm just waiting for them to be in stock

Since these are neutrally timed, did you discuss advancement with John or do you feel there is no need for tweaking.

And just out of curiosity, did you choose bolted or soldered brushes?

I left the timing Neutral. The brushes are fixed with screws, not solderred.
