Help with choosing parts for a first robot, please.

Thanks very much for all these responses, guys! I've been combing the internet for information about this for the past 2 - 3 weeks, and for whatever reason never thought that the Fighting Robots Association forums would have information about fighting robots!

I'll go ahead and get a Dx6i, then. Building robots is something I've wanted to do since I were a little tot watching it on TV, so I don't think I'm going to lose interest anytime soon. (I'm more concerned about running out of money for this rather than running out of interest.) And I'll definitely include a removable link, thanks!

I live in Perthshire, and by the time Comic-con is on I'll be at University in St. Andrews, so I'm not sure if I will be able to go that. :/ Are there usually any events here in Scotland? I thought they were pretty much always in England, so I've only been to one in Barnsley about 5 years ago. If there were any more local events at suitable dates I'd definitely go, competing or not! :P

Ok so my drills arrived yesterday, Yay! But the reverse threaded screw in the clutch seems to have a torx head, and annoyingly I don't have screwdrivers for those. This may seem like a silly question, but does anyone who has opened up Black and Decker drills before know what size screwdriver is generally needed for these? (I'd totally measure it myself but I can't really be accurate as the chuck is in the way.) I'd rather spend money on 1 good screwdriver that fits instead of a pack of different sized naff ones which will get chewed up easily.

I'm starting to think of trying a 4WD wedge robot, but I've just watched a Youtube video showing the insides of Tormenta 2 and noticed that it used only 2 85A Botbitz ESCs for 4 wheel drive. I was just wondering how that is wired, and if people usually use 2 ESCs for 4 Wheel Drive Robots? I thought that only 1 of those ESCs was used for each motor.
Thanks.
