Speed controller

Hmmm, that sounds like Hannibalitos layout. :)

was similar Leo but would proberbly stand a little taller, good luck Philip im in bris til dec 22nd then im off again, more than willing to help u out if u need it

Thank you, Craig. I am unemployed ATM so I probably wont do anything much until I have a job.

Where are you going next?

Does anybody know if these are any good http://cgi.ebay.co.uk/Mystery-RC-30A-Brushlessmotor-Speed-Controller-ESC_W0QQitemZ220191292118QQihZ012QQcategoryZ123849 QQssPageNameZWDVWQQrdZ1QQcmdZViewItemhttp://cgi.ebay.co.uk/Mystery-RC-30A...er-ESC_W0QQite mZ220191292118QQihZ012QQcategoryZ123849QQssPageNam eZWDVWQQrdZ1QQcmdZViewItem . I was thinking about using them for my drive (1 per wheel, 2 wheel drive) which I think is going to run at 18v

If you are planning on using brushless motors they may do ok (I havent got any experience with brushless) but I believe you are thinking about using 18v drill motors?

In which case these wouldnt be suitable.

Tim, I assume you are using standard electric DC motors in your robot, in which case these controllers wont work. Brushless motors and brushed motors (your standard DC electric motors) differ from each other and require different methods of controlling them.

So unfortunately, the above option wouldnt work for you

EDIT: As Gary said, he beat me to it :)

If you are planning on using brushless motors for drive i would stay well away. Weve tried it, and spent ALOT of money trying to get it right. In the end it took two years for a company to develop the custom speedcontrollers for us to use that actually appear to work ok. next to each other.

Ok Thanks Guys appreciate your advise. What would be the cheapest speed controllers I could get for now even if they only last a couple of fights and I replace them later, and yes I know that is a false economy

Bit of a tricky one there on 18v. There are a number of cheap options for a 12v system but if your determined to go for 18v then I would recommend going for something proper now.

I have found with a featherweight that generally as the voltage goes up so does the cost of the machine.

You will probably be looking to spend around £80 unless you can get something second hand.
