Last I read holmes has not used the hobbywing 1080 to answer this. But I want to know as well. Even though I don't think I could ever be happy with the sound of an out runner.

I have 5 TRX4s 1 of which is equipped with a Mamba X and 1800kv Revolver in my #1 chassis. The remaining 4 TRX4s all have HW1080 with various motors ranging from the stock Titan 21t, HH Trailmaster Sport 550 and a pair of HH Crawlmaster Pro 550 12t. My favorite combo is the the HW1080 and Crawlmaster Pro 550 hands down the smoothest slow start up.

Remember the HW 1080 is only for brushed motors... I have it paired with a HH Trailmaster Sport 550 21t in my Ascender and also have one to be installed in my TRX-4. It's a fantastic budget setup, but there are advantages with the Mamba X / Revolver brushless outrunner combo in my Bomber... I can run 4S if I want, and I have the Aux Wire function on my 3rd channel serving to change the mode from Rock Racer to Rock Crawler, turns the drag brake on and off. |

I’ve gotten a little wheel time with one now. They aren’t too bad, but I haven’t tested with the crawlmaster to really see low end resolution. | ||

Thanks John that was my thinking also, I actually wanted a BR XL but can’t find any in the states. I love my BRMD , but don’t think the BR mini would handle the weight and bec needs for a servo, or am I wrong again ? Hang up and Drive Last edited by mikemcE; 01-07-2019 at 04:49 AM. | |

John, Few questions. I’ve got a crawlmaster pro 13turn. What does that equal roughly to a regular 540 motor speed wise? I’ve got a custom build that I’m taking the gear down volt up motto to the max. I’m at 96:1 total reduction. I ran it with one of your trailmaster sport 550 can 27 turn on 3s with a 1080 esc. The low end smoothness was great and top end was slow to be expected. About a slow walking pace wide open. I just bought a brxl and want to go 4s power. I have three of your motors on hand. 13t crawlmaster pro 540, trailmaster sport 27t and 45t, both 550’s. If gearing is kept the same, which motor will have the smoothest start up and top speed a little more than my current combo. I can change pinion if needed but figured I’d keep that constant to see which motor I like the best. Right now I’m at 15t pinion and 86t spur. I don’t NEED the 550 power as it’s a leaf sprung scaler around 9-10 lbs but I had them on hand and figure there’s no replacement for displacement. Thank you. Ben |

This might help you from Holmes hobbies website. Below is a list of motor turn counts and speeds. Motors on the same line have equivalent speeds. Sent from my SM-J737V using Tapatalk |

JRH - will the recently added DRAG BRAKE RAMPING feature for Mamba-X become a feature for your BLE series ESC's as well? I'm loving the feature now with my Mamba-X and 1800kv Revolver. I'd love to use this feature for my Truggy that's using the BLE ESC and 3500kv PP Stubby.

What is the difference between copper and silver 'stand up' brushes? Should I have a pair on standby? Or, how long does a set generally last in a Torquemaster Expert? And how do we tell when they need to be replaced? Is there other maintenance required on these motors? |

John, quick question about the blh servo issues... I had you send one to me in the UK a few months ago. Due to working away a month at a time I've used my new trx4 truck and servo only a handful of times and I've actually changed the radio gear as well. How recent was the batch with the issue? I ask because the first time I used the truck with the traxxas radio after a firmware update the servo was acting crazy at random points. I then updated the firmware and it seemed ok. I have since changed the radio gear completely to a different make and it still seems ok in the couple of times I've used that. I'm assuming mine is ok but just wondered if you had seen any that started working after they showed some signs of problems at first. Cheers |

Thanks, looks like I'm safe then, it must have been a dodgy firmware update on the controller.

John, please see post 1008. I got skipped over yet again in this thread. Thanks. Ben |

For your second question the 13t crawlmaster will probably have the smoothest startup and will have a higher top speed then a 27t 550 motor or 45t 540 motor. at 96:1 the tops speeds with 4.2in tires on 4s are 4.23mph on the 13t crawlmaster 540, 2.88mph on a trailmaster sport 27t 550, and 1.92mph on a trailmaster 45t 550, the crawlmaster 13t on 3s which I think is your current setup is 3.6mph for refrence. not knowing the condition of your motors its hard to say. the trailmaster sport motors have a torquier startup like the torquemaster motors. Plus the 550 motors I believe have a higher startup speed. Since your not changing gearing and your crawlmaster is your fastest motor I would say its going to be the fastest and smoothest. If you had a slower 20t 540 crawlmaster and planed on gearing them to the same top speed it might be a different story. | |

| Re: Have tech questions? Will answer. No it didn’t. The purpose of this thread is to ask John Holmes a question and have him answer it. Not every keyboard warrior on the forum. If I wanted a million incorrect know it all answers, I would have posted a separate post. I’ve seen that graph and understand it. There is a technical level to these motors that myself and I bet most don’t understand so that’s why I want an answer from the guy who designs and builds these motors. Is my question life changing or super important? No, but I’d like an answer if possible, not a “pretty much, I guess, or my buddy thinks this type of answer. Ben |

Indeed. None of us have used his products, or had first-hand experience with them. We're just bored "keyboard warriors" stumbled across this site and decided to take a stab at answering random questions.
