I am running 2 of the Banebots motor/gearbox combos. The gearbox is 16:1 and the motor is a 18V RS775. This is the most powerful set up possible with a sensible top speed of around 10mph. The previous 2 machines had 4 GR01's as their drive and it was just to much weight: 3kg alone in drive. This set up is more powerful but only weighs 1.8kg.
I cant double up the front wheels cos I have to get a pulley in there to drive the front wheels but it will be enough on its own, I am sure. If not I can go for the 40 or even 30 shore wheels rather than the 50 shore I have just bought.
The next machine I build will be totally new. We have plans for a 4WD bot with a 50mm bore, 100mm stroke pneumatic cylinder firing a spike out the front. I doubt it will be used in the champs cos of all the spinners but it will make a fun machine to use at live events!
