Oh How Original Posted April 1, 2015 Share Posted April 1, 2015 I could have maybe put this as a status, but just for those running brushless combos in your crawlers (primarily SCX10 or Gelande 2) could you post your electrics below and what sort of run times you get from your chosen packs? I'm considering doing it, but I haven't done much reading up on what people use and what sort of run times to expect. I know I can get 3 hours on the brushed set up, I'm expecting a brushless system to be a bit less, but just wondering how much?

Alex97 Posted April 1, 2015 Share Posted April 1, 2015 This wasn't for a crawled but when I went from brushed to brushless and the run times reduced by about 55%. Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted April 1, 2015 Author Share Posted April 1, 2015 Bit different in something faster though... I expect it's pretty close to that though to be honest, I can't see over an hour being possible. I might be wrong though. Quote Link to comment Share on other sites More sharing options...
Noj Posted April 1, 2015 Share Posted April 1, 2015 Well, I ran my wraith (not the fastest, 35t igified tamiya can) with a 5000mah 25c over lander 3s for a full afternoon without hitting lvc, running a savox 1256 on an mtroniks tio crawler ESC and no bec! Get me, Mr lah dee dah no bec with a savox Quote Link to comment Share on other sites More sharing options...
Geeze Posted April 1, 2015 Share Posted April 1, 2015 A few folk running brushless around here in their trail rigs and the general consensus seems to be that run times are about the same if not a bit better. I'm tempted to join them, sensored systems now getting quite cheap though waterproofing is still an issue Quote Link to comment Share on other sites More sharing options...

The rig I'm thinking of doing it in, won't be getting wet, so the waterproofing side of it doesn't really apply. Any water I will be going in will be limited to bottom of the axle sort of height, which won't cause me any issues. Quote Link to comment Share on other sites More sharing options...
Noj Posted April 1, 2015 Share Posted April 1, 2015 Having re-read your initial post, my words were irrelevant and useless. I shall join dannyp in the Vat of Stupidity. Carry on Quote Link to comment Share on other sites More sharing options...
Si Coe Posted April 1, 2015 Share Posted April 1, 2015 Most people going from brushed to brushless in non-crawlers also go for significantly quicker motors too, which is what burns through the juice faster. However, people that switched to equivalent speed brushless systems (those running fast brushed or stock spec mostly) tended to find brushless more efficient not less. That said, at low speeds there is little efficiency difference between them - friction on the brushes at speed what makes brushless more efficient.

That said, at low speeds there is little efficiency difference between them - friction on the brushes at speed what makes brushless more efficient. That's interesting, I would be wanting to be around the same speed as I am now, maybe just a touch faster, but nothing stupidly fast... A brisk jogging pace maybe.

Doesn't seem to be any consensus on specs, everything from 13.5 to 21.5t, most on 2S. HK do motors for 25 quid and they seem to be the popular option, ESCs are varied again, I've been looking at the HW 60a sensored one, had good experience with HW so far Quote Link to comment Share on other sites More sharing options...
Gaz! Posted April 1, 2015 Share Posted April 1, 2015 Honestly dan, it's not worth the extra outlay converting to brushless. Only real need for brushless in crawler was the losi worm drive crawlers, they were so power hungry that brushless suited them better than brushed. But for crawling brushed is still very much king.... Quote Link to comment Share on other sites More sharing options...
turok007 Posted April 1, 2015 Share Posted April 1, 2015 all im saying is the GOAT is fantastic. (it will be in the FS soon) Quote Link to comment Share on other sites More sharing options...
Gaz! Posted April 1, 2015 Share Posted April 1, 2015 Yep, the goat is by far and away the best brushless crawler set-up there is but still very unnecessary.... Quote Link to comment Share on other sites More sharing options...

But for crawling brushed is still very much king.... For the same speed and power, I'd pretty much agree, the main benefit seems to be less maintenance. But there are occasions when trailing when a bit more pep is fun, and that's what appeals to me. Not silly speed, just brushed on 3s levels available when you want it. Also really handy for powering up steep banks and we've got quite a few of those on the local trails The combo I'm looking at would cost less than 70 notes too so its not even that much extra outlay these days Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted April 1, 2015 Author Share Posted April 1, 2015 I did think as much, I just fancied trying something different to be honest. It wouldn't be for a little while yet anyway, I have other things I need to purchase before then and cash is a little thin since deciding to keep the TF2.

mxfun Posted April 2, 2015 Share Posted April 2, 2015 (edited) Am I right/wrong in saying brushed motors are more controllable at start off and lower speeds whilst used for crawling Edited April 2, 2015 by mxfun Quote Link to comment Share on other sites More sharing options...
NuttyProfessor Posted April 2, 2015 Share Posted April 2, 2015 I've never needed a Bec with my savox 1256TG, been in 4 cars with varying esc's and not a sausage. Never tripped out even running lights etc. Quote Link to comment Share on other sites More sharing options...
The Dark Knight Posted April 2, 2015 Share Posted April 2, 2015 I've been running a 21.5t brushless setup in my SCX10 and been impressed with it. One thing though, I've never fully submerged in water and don't really plan to either. I use the Hobbywing Juststock esc which is really good for the money and easy to waterproof. I take the esc apart and fully coat the boards with Lazy Goo, put it back together then Lazy Goo all the joining edges and all around the sensor port and wires. I used the same esc and waterproofing method in my touring car for racing last year with great success. Waterproofing the motor is something I'm not 100% confident about. Yeah you can coat the sensor board in Lazy Goo but a lot of brushless motors have cut out vents in them, so I wouldn't want to submerge it. You do get sealed sensored brushless motors but I've not had any experience with them. I only run on 2S and been using a 4200mah 65c lipo, I get at least 2 hours run time with it safely. I've got a 21.5t brushless motor for sale if of interest to you but I've been tempted to keep it and put in my mini. Quote Link to comment Share on other sites More sharing options...
Oh How Original Posted April 2, 2015 Author Share Posted April 2, 2015 Am I right/wrong in saying brushed motors are more controllable at start off and lower speeds whilst used for crawling Against sensorless systems yes they will be, but a sensored brushless motor and ESC will be just as smooth as brushed. I don't think I'll go ahead and do it, if theirs no real advantages to it. I have my SCX10 which I can fully submerge, should I wish to, so the waterproofing isn't an issue. But if theirs no upside apart from a little more wheelspeed, it'd make more sense to spend Quote Link to comment Share on other sites More sharing options...
