I haven't really been involved in any RC/4wd of late, but would like to get back into RC crawling.
I would like to mod the rig a bit before I take it out, like upgrade the motors with brushless.
Been looking on ebay and really I am lost on what is going to give me optimum torque and power.
Has anybody looked up brushless motor on ebay?
There is a few 540 style although very limited, but heaps of plane motors that some will suit for mounting and shaft size.
Has anybody experimented with something outside the circle?
There is a 540 motor they advice may or will destroy current gears and a need to upgrade is assential.
This is the stuff I like to here.
Go to ebay and type in (RC MOTOR 540), its black and comes with a ESC. Don't worry about the ESC, just interested in the motor, has anybody tried these? Razz
All my gearing is metal driving drop axels, so I have already pretty strong running gear. Just after more grunt Very Happy

Mate i would'nt run brushless in a Clod, Benno did it and blew both diff's in a course Twisted Evil , far to much power for them to cope with,m and he had the best of the best as far as axles and gears went Shocked Very Happy .

Get some 55t integys, throw in some 8t pinons and a big LiPo and crawl for hour's armsup

Smile Has anybody else tried brushless. I want more power but also wondering if the torque is there.
I'm assuming the less windings creates more power but less torque.
Surely if my gearing is all metal, than running portals I should be able to handle some more power Very Happy
Having the portals will reduce the load also on the running gear armsup
I know JK did some test in a mag on the brushless, but that was when they first came out,perhaps than too they weren't as powerful.
I best buy me a pair of brushless, gotta see for me self, worst I can do is twist a casing.
I will post the carnage results once I get hold of some off ebay. Very Happy Very Happy

Brushless motors have shit loads of torque, thats where the problem is. They are in fact a 3 phase dc motor. It is hard to stall a brushless, they just keep going. I have a 605w 850kv 540 size in my axial, and I keep screwing drive shafts apart, I have now ordered a slipper clutch for it.

The other downside of brushless motors is that you need 1 controller per motor, you cannot run both of the one controller.

There are a couple of guys who run brushless clods, it would be better to ask on www.thecrawlpit.com or www.rccrawler.com/forum/

Thats where most of us crawlers hang out now.

Hope that helps a little.


Brad.

Hey Gigantor what type of portals you running? The rccrawler or integy portals and you had any problems with them? I've heard they're pretty weak but they might have been running some ridiculous oversize brushless motors on them.

I run brushless in non-crawler cars and they have heaps of torque. Even in a car that was designed for a brushless motor, I am still cork screwing the drive shafts. I think you will find they are just too much for crawling.

When you say "don't worry about the ESC", you do understand that you need a brushless ESC to go with the brushless motor?

Hey guys, thanks for the info.
JK where you been hiding? or has it been me ? Wink

Didn't know they were a 3 phase d.c motor and also didn't know you need to run a brushless ESC Crying or Very sad
Thanks again for the info.
But it won't stop me Very Happy I'll let you all know how it goes and if doesn't go or that well I will show you the pieces of the aftermath.
James Lost your number, can you give me a call

The question about the portals being weak. You are correct!! I bought from RC4wd and have ripped 3 a part so far, He has replaced them with complete new set and said try this version, so hoping they stand up to a pounding, the first ones were like after market CV's must have bypassed the heat treament section of production line. Rolling Eyes
They stripped out just normal easy driving.

Can you parrallel 2 x ESC together using a Y lead?

I'm also now into RC Boats with my boys, so we're going to try these motors in these as well.

Man its fun having two boys Laughing Laughing Laughing

if someone was to put brushless motors in a clod what size would they get?

Ha, I bought some 540 Feigao Brushless Motors $100 each 5915KV, using a 11.1volt Lipol that equates to 11.1 x 5915KV = 65656rpm
I think thats right, ESC are pretty expensive as well for such high current draw x 2. I tried to buy the alloy clod gear casing, all sold out.
I have metal gears, but I think the plastic case will self destruct on full throttle. Very Happy probably strip the useless portals out as well.(oh thats right they strip out under a 7.2v batt running brush motors not doing anything)
Anyone got an alloy clod gear casing they want to sell x 2. Laughing
Cheers Shane

With those motors you will not be able to crawl at all. Way to fast. May be ok if you want to race. All you will do is destroy the gears. You need around 1000Kv for the best results.
