Im in with Blazer:

80*210mm ram (producing about 512Kg of force), 2x 1litre buffers, 3/8th high flow valve, 1.1kg of gas (about 52 flips), 2x 400watt wheelchair motors powered by a Vantec RDFR23. The robots basicly done, just needs the new armour sorting (mixture of ali/steel/HDPE). At RAF Cosford it weighed 40Kg with the thin ali armour.

aaahhh when you said about info about flipper right its one i built from parts of others which were cut down, its aprox 55mm x 150mm i have no idea what force it is which is what i assumed you were asking, im using 2 ncc70 controllers taken from my heavyweight and 2 12volt x 7ah batteries basically bits and bobs ive collected over the last year or so from various friends, at the moment im guessing its gonna be right at the limit of middleweight, so i may have to fore-go armour and hope i can flip any really savage cutter or spinner before they get me.

Sean: the most dangerous opposition looks to be from the American machines which are both spinners, one is a drum spinner and the other is the undercutter.
It looks like the middleweight class is going to be exciting and dangerous even though there are only 8 entries. Seems there will be 3 spinners, 2 flippers, 2 pushers and 1 unknown (GreenMeanie.

well it looks as though my machine may come home in a bag then :sad: i cant stand spinners far to dangerous, they should stay in the heavyweight class.
well if alans robots is like mine it could be a pusher as well as a flipper because wheelchair motors are designed for some serious torque, i dont know about yours but mine is rated at 11nm to start with and builds from there, i dont know what its stall torque is ive never tested it.
anyone else know anymore about their motors?
