The motors would work, but there's far better ones out there (drill motors, Speed 900s, Gold motors, etc.)

More worrying is the fact they come from Xbotz, I've heard several peoples' reccommendations with quite worrying details that would make me advise you to not touch Xbotz with the proverbial bargepole, get your motors from somewhere else instead.

http://www.fightingrobots.co.uk/forum/v ... f=3&t=2565 should tell you most of what you need to know on that front...

And the 'blue' wheels are fine, most featherweights use them actually :)

as joey said, xbots have been known to be a bit dodgy, id steer well clear of them if i we'r you.

however, i looked into those motors when i was first starting out in featherwights, they would work, but tbh speed 900's, golds and even drills would be better and probably more reliable.

Looks like I've got me a rival.

Before you criticize another person, first walk a mile in their shoes. Then, when you critisize them, you'll be a mile away and have their shoes.

I have:
-No tools more complicated than budget jigsaw
-PVC and floorboard for armour
-A shed
-No experience of featherweights either
I'm less of a worthy rival than you think.
BTW you said no idea twice :D

Motors can generally take 50% more than they're meant for safely so 14v would be fine. I'm personally using a sabertooth 25A which cost about ?100, a fair chunk of the budget (you could probably build a decent antweight with it). You could probably find a slightly cheaper on with less features but I wouldn't know anything about that... :)

motors will take double the voltage they're rated but double the voltage double the current quadruple the power that sounds brilliant but the life of the motors is vastly reduced when you do this

12v drills on 14v will be perfectly fine

lookin back through feather topics and posts i see that Simon Windisch used 2 50a boat speed controlers in someones in the kitchen with dynamite and wondered if i could do the same with 2 60a ones from giant cod, ideal use for at least one fihgt with out exploding :-?

My boat controllers outlasted the motors and armour.
