there's a cheap setup

[harry hills]

maybe in magic land

[archie2000]

what's wrong.
brushless is still good right

[harry hills]

terible esc will probably bust into flame and melt as soon as you blink near it, and what looks to be a pretty sub standard motor for this purpose.

brushless is good, hell i am going to be using brushless in a fw but leave these things to people who know what they are on about(not in anyway saying i am one, not by a long shot )

[archie2000]

OK
I know fans are rubbish.

With brushless, you tend to get what you pay for. If a reliable and good-quality brushless setup cost just £39, then everyone would be using them. But they're not, which speaks volumes for the reliability and quality of the above brushless equipment. Maybe alright for planes (for which they are designed) but not for robots.

One downside with car fan motors is that they're second-hand and come in varying degrees of condition. But if you get a decent one, it will be as good a power source for a spinner as you can get. Dragonstrike uses them to good effect, and more recently (although briefly :wink: ) Bitza Mk.2.

Jamie, you went brushless in drumroll right? How much did you pay for that set up?

[RogueTwoRobots]

I did indeed. The cost was as follows:

Scorpion motor: £85
Hobbywing 150A ESC: £68
Lipo batteries (not an essential part, but it's hardly worth going brushless without them): £40

Total: £193 (£153 without lipos)

Not cheap but definitely not the most expensive setup around. The motor I used was a Scorpion HK4020-1100kV model that I got off an eBay seller, but he doesn't sell that specific model now. The closest model would be: http://www.ebay.co.uk/itm/Scorpion-HK-4 ... 470wt_1037

I think that's the same motor that 540 uses. The 4025 range has slightly more power than the 4020 model I'm using.

The speed controller is this: http://www.ebay.co.uk/itm/Hobbywing-EZR ... 139wt_1037

Recommended to me by Graeme from the Big Nipper team; they ran it in Buzzbar last year with a massive motor. Didn't once let me down last weekend and is still running well, although it is quite over-spec'd. It's got a low-voltage cut-out built-in so that you can protect your lipo batteries from over-discharging, as well as several other adjustable/programmable settings. Definitely a worthwhile purchase for anyone looking to go brushless.

LS4 is running a HK-4035 Scorpion (around £120 on ebay) and (i think) a £180 ESC, then 2 5 cell lipos joined together permenantly to form one 10 cell, then the 10 cell charger on top of that... around £400-500 depending on where you get it all from.

I was thinking of going brushless next year but I have bigger issues to solve atm, like raising my disc up and stopping my Speed 900's from going up in a big plume of acrid smoke.

edit: and replacing the whole base plate on conker
