best brushless motor for downhill crawling

[cobaltracer1986]

This has probabally been answered.. i cant find it tho

I now have a MMP with a orion vst 17.5 out of my 1/10 scale buggy on my scx10. It does ok. What the problem is tho, is when im going downhill i have 2 options.. freeroll or stay stopped. Iv seen some people say thats how brushless is but i only believe it to a degree. I was looking at the roc 412 or the pro 4 motors.. iv already went over budget so on a motor i have no budget.

Is there a setting im missing in the castle link? Also controllable are these motors do for going downhill?

I have a HH Trailmaster BL pro and get a nice controlled down hill crawl out of it..

HH also has the new puller pro BL motors. They are 4 poll motor's..

I've ran, redline, Pro4, and Pro4 HD.. All ROAR approved motor's, set to guideline's..
HH has no guideline's, just performance in mind!

They are built specifically for us, the Crawlers!

Holmes hobbies ftw!!! And yes sounds like you need to adjust the drag brake in the mmp through the castle link

Ok cool ill look into the hh motors. I just want to play so sticking with rules doesnt concern me. My break is already set at full crawler. I know a low torque race motor is part of the problem but dont want to drop cash on someyhing that has the same problems

So in your case you found the hh work better for your application( worded it like that so a flame war dont break out)

I have a mmp with roc412, i think my drag brake is set to 80% and on the street its waaay to much, it will front flip the truck like nothing. On steep downhills its perfect. You definitely need to adjust mmp settings.

This is confusing, your drag brake or are you talking about crawler reverse?

My drag brake and i also have crawler reverse. Iv checked the settings a few times to make sure its correct. It xould be just the motor that doesnt have the holding power.. i can creep down hills with no theottle.. very very slowly but as soon as i touch the throtte.. even a bit it free rolls then once i let off it almost front flips from the drag break


Basically im seeing who else uses what and how their downhill performance is.. i love playing on hills but dont like not having descensing control on the steep trails. As far as people say i cant have brushed descensing control but i dont believe that i cant get close with all the powerhouse motors that are out.. Keep in mind this isnt a crawler motor. Its a 17.5 mod motor used for a 1/10 scale 2wd buggy.

I agree with Yoda.. Check your drag brake settings first..
My Sexo is on 60% drag, but it doesn't hold so well on the rocks, but won't front flip when I let off the 30mph throttle..
Class 2 is set to 100%.. But weighs enough to not flip on the street from 20mph..

"Work better"... Hmmm... I'm a long time Tekin fan.
My brushless rigs are either running Tekin RS's or RX8's..

So while I enjoyed the Tekin motor's, I didn't find them to hold up to the riggers of my use.
I had the magnets pull loose from 2 rotors in the pro4's and something is up with my Pro4 HD.. Just haven't had time to pull it yet..

I've been trying the Trailmaster BL's since they came out, with no issue's.

The low end torque is stronger, crawling is smoother, and high end is right there with the Pro4's..

So yes, for my applications(crawling, trailing, power, and durability) the HH suites me better. [emoji106]

Sounds like you should adjust your throttle curve in esc. Mine is setup like a turbo car with some turbo lag if that makes sense. If you haven't touched yours then its a straight line up. Try making it more of a curve up and later on powerband so your down low throttle is more control-able, basically it will take more trigger to get it moving but your first half of the trigger pull is basically nothing, so when you BARELY move the trigger, it won't take off as fast. Super hard to explain but try adjusting your throttle curve.

What is your drag brake set at?

Question for ya, im guessing you only run 3s in everything? What kv have you run in the pro4 hd? I really want to get hh 540xl and run 3s but i have 4, 2s batterys just sitting here and i kinda want to run 4s sometimes but 540xl is 50k max rpm so that's out of the question, so what kv pro4hd on 3s (top end wise) is comparable to 540xl? Is the hh 540xl on 3s enough? Im tryin for stupid retarded power and speed.

The pro4 hd 3000kv can run 3s and 4s, hh 540xl 3s, or get hobbywing 4000kv on 3s.

3s.. Nope, never ran 3s on brushless.

Scratch that, I did back when I had the 13.5t redlines..

2s x2 Only!

All my brushless setups are running 4s!

I have ruined a couple pro4 4000kv motors on 4s.. They have magnets around the rotor, that pull loose/separate..
Pro4 HD in 3000kv and 3500kv.

HH Trailmaster BL 3100kv and the new Trailmaster BL pro 3300kv..

All 4s and 20mph to 30mph..

Get ready to replace stuff!

As soon as I get another 540xl, I'll be running it on 4s to its death! (If that ever comes!)

The Trailmaster BL has a Solid rotor.. No magnets to pull off!
I've been running mine since the day they came out.
I've had them so Hot, I couldn't lift my Sexo up from the bottom of the skid!
So I'm hoping the 540xl is the same.. I can't kill these motor's!

Over geared, 54/13, on 4s, running RB2's, slow crawling with Nasty torque, to open throttle and let shiz fly, 25mph! Still going strong!

 

[cobaltracer1986]

84yota , yes i have a small curve to it probabally not enough. Im set at 213% drag brake. I think my problem is that i have a "far from crawler applications" motor. Im looking into the HH brushless now


Winnerone. Whats your take on the differences between the new 540 puller brushless and the trailmaster. Therez a nice price difference.


I have a 7-8lb scx10. Geared for about 8 mph. No need to go faster than that foe what its used for.. any quicked and itl get jumped over things that it shouldnt jump. Always running on 3s

Yeah, that's probably ALOT too much drag break! Lol..

As for the difference between the 2 motors..
The Trailmaster BL is 2 pole, buy highly comparable to a pro4, not a redline..

The puller pro is a 4 pole motor.

I haven't gotten one for myself yet, so I can't give you any experience on them.

Yes, that exactly what happens when the go faster then "Needed".. They get jumped on to, off of, and over obstacles! Lol..

That's about all I can comment on, without first hand experience, of the new puller pro's..

There's your problem right there. Had same issues with my 13..5 mod and my 6.5 mod when seeing how they react

 

[idaho]

Sounds to me what your experiencing is the drag brake turning off when you get on the throttle, I've experienced the same thing and it always frustrated the hell out of me.

 

[Olle P]

Worm drives in the axles will make the problem go away regardless of motor choice! :twisted:

 

[skerb]

I had the same problem with my roc412 and eventually went back to a handwound 35t brushed motor purely for the downhill control.

 

[cobaltracer1986]

Idaho, how did you fix your issue.. or didnt you?

Jokers. Yes that is my main problem. Just doin research before i buy since my experience.. even tho wrong motor, was bad for downhill , but awesome everywhere else

The freewheeling after applying throttle is the only downfall of sensored brushless in crawlers. Gearing/drag brake and driving style are the only ways around it. The gearing is the leverage against the drag brake, a somewhat light drag brake will allow you to crawl downhill without throttle. Steering also slows a descent, when applicable.
