I'm Thinking Of Building A Feather, And Need Some Advice

James you sound very bitter,

Ive already put it in writting on the forum, and il say again. anybody who buys our speedos and smokes one will have it replaced free of charge.

My surggestion is that you call Mtroniks, speak to the tech department about your case and im sure they would be happy to help. Sounds like you had a faulty one. If not i would be happy to have a word with them for you if you like?

Lets try and keep topics productive :)

Just needing some simple advice or assurance regarding speedos:

Im finally gonna be getting round to getting some speedos (and getting rid of those damn microswitches :)) Im most likely gonna go for the Electronize 30A with ex relays - should these be okay for using with both W/W motors and drill motors? I reckon they should be but thought I ought to check anyway.

Cheers
Lenny

Yep they should be more than fine Jamie. Go For it mate.

Mr Stu

Thanks, have to wait a week or so until my student loan comes through (thats where Im getting the money from - instead of buying books for uni :)) but will be good to get them

LOL!!!!!!!!!

Stupid thing to do, student loan is for Uni Mr. God some people.

Mr Stu
(Know the feeling, my Student loan is paying for my new Laptop LOL!)

I would want a low 150psi pneumatic system.

Not bitter at all James, just making sure our friends like Mr McHarg dont spend all their student loan on motor controllers sold as unblowable, which are quite easily blowable. In fact, since my last post Pete from the Bloody L team has been to see me with another blown MTronics controller.

Thanks for the offer of talking to MTroniks for me, but I managed to do that myself, and they did indeed offer to replace the speedos if they are manufacturing faults, but be advised anyone purchasing these, if they blow through overvolting, or back emf generated by motors bigger than those used in RC cars, you are unlikely to get your money back as they are not designed for robots. In fact, MTronics only have 1 controller designed with robots in mind, and they are for motors that dont work in the robots that have tried them.

As I said, Mtroniks do excellent controllers, I personally own over 40 of them at the moment, but they may not be suitable for featherweights, and to be honest Id think twice about using them in a decent 6kg robot. They simply cannot take the spike loads we would give them in combat, in machines heavier than RC Cars.

Good luck with your robot building Lenny, but make sure you do as much research as possible before buying anything, as it is very easy to buy something that someone has reccommended, and find it is not what you need.

I would pesonally always reccommend the electronize range of controllers to any first time builder, and to us older blokes to. They are by far the most flexable and reliable controller for under £50, in my experience anyway.

Thanks for the advice James. Ive been looking into all the options for a while now and Electronize (from what Ive seen and heard) seem to be a decent choice. There are of course the slighty fancier options like the IBC but its a bit out of my price range atm and does a helluva lot more than I need speedos to do. Still got a bit of research to do into it but Im 99% sure just now that Electronize is what Ill go for :)

Lenny

Ive found no problems with our range of speed controllers and they have handled running drill motors in robots that ran for 10 hours a day none stop.

Hence the guarrentee that if you were to blow one it would be replaced free of charge, so you cant loose out. If a motor too powerfull were to be run on one the speed controller it would simply shut down.

Electronize are great speedos and have been used for a long time in combat robots. the only down side is that thy weight 3 times more and they are twice the size of the Mtroniks which are a world wide distributor.

Also Ive got to say there perfomance is as good as the electronise if not better, As its all solid state electronics, no relays involved. The robots ive driven with Mtroniks installed have imediate reaction times and drive very nicely.
