hi guys, thinking of starting to build a bot. Am going to use to drill motors from argos. thing i want to know is what type of speed controller will i need and will the receiver over heat if i run them at 12v?
The reciever doesnt have any troubles overheating with the speedos. Those parts are seperate.
Speedos useable are
Electronises- http://www.technobots.co.ukwww.technobots.co.uk
IBC http://robowars.org/store.htmlhttp://robowars.org/store.html
or the sidewinder. (James baker sells these)
Other options are the M-tronics or the Schulzes you can buy in the RC shops. Take care and dont go for low amp ones or the ones without a reverse.
And of course the speedos Leo has. (contact me for more info)
would the Electronize 15A + 5v be good enough and would i need one or two?
The Electonize 15A + 5V would be good yes - thats part 1500-013 isnt it? If so, I would personally pay £3 extra and go for the 15A microprosser controlled one (with 5V reciver output), part number 1500-015. Ive not used them personally but they are meant to be much better than the non-microprocessor ones. And with Electonize controllers, you would need two - one per side of your robot. The IBC and Sidewinder controllers Mario mentioned control both sides from one board but they are more expensive (although I believe their performance is much better than Electronizes but again, I havent used either)
Good luck with the bot building
ok cheers mate
what do you think of these?

Those will be ok, both seem to have BECs on which is good, (you only need one to have a BEC but that doesnt matter). The seller is well known to most of us also.
Ive been keeping an eye on those
(EDIT: Ed pretty much said what I was gonna say, he just beat me to it

ok might sound stupid but whats a BEC?
Battery Eliminator Circuit - it allows you to power the receiver from your main battery supply rather than have to worry about a receiver battery and keeping it charged etc
