Ok I'll stick to the one motor, it was only that it fit quite nicely having 2 motors but 1 will work. I also figured that whilst there was more to go wrong it also meant if there was a failure of one motor, belt or ESC it would still keep working for the rest of the fight or even for the rest of the competition.

The plan with the wheels is to have them come back over the motor/gearboxes allowing me to have reasonably wide wheels but still keep the robot narrow

If you do it right you should only ever need 1 motor and 1 ESC. Binky has been using the same Motor and ESC for 3 years, unmodified, and many machines have been running the same parts longer than that.

We use thin walled plastic RC hubs on the current generation of machines.
Didn't have to replace a single one after a year of fights.

And yes, the hubs have enough space to fit a GR02 in, with the frame to support them.

Do you have a link Mario?
I've been looking at getting something like this: http://pages.ebay.com/link/?nav=item...obalID=EBAY-GB
But was planning on just removing the tyre and making a new aluminium hub but perhaps I wouldn't have to bother

No link needed, as you're spot on. We have hex 17 wheels.
Larger wheels, like 1/5 or 1/4 scale are hex 24.

If those wheels can take an 2 kg RC car @80kph doing a Dukes of Hazard over 20 meters.....

Hi Mario, out of interest how do you go about connecting this type of wheel to a GR02? If I understand correctly the wheel is designed to take an M10 nut but I guess you make up some sort of custom adapter?

Max, to fit the RC wheels to a GR02 or any other live axle I make a custom adaptor, Hex 17 or 24.

To ensure the hex staying put on the shaft, I glue it with Loctite 638 and tighten the setscrew.

Just carry a spare motor, ESC and belts. If you lose your weapon during a match, just try to win through driving and then swap it out afterwards. Also buy a decent motor as well, will help towards having a reliable weapon system. My original brushless motor was on the go for three years (or three events, depending on how you look at it) and probably would still be going if it hadn't got vapourised in a massive impact. It's a 40-sized Scorpion motor, more expensive than some Hobbyking options but worth it in my opinion. If you scour eBay you can usually get a used one in great condition for about half the 'new' price.

360 had 2 brushless motors, can see why you'd want to do itâ€¦ redunancy etc, but the power gains arent really noticeableâ€¦ and if the one motor buggers up, the chances are it will lock up - causing the 2nd to fail anyhow. Buy once and buy good quality.
