That's yet another combination. The windings from a 900, and the axle of the fast-runner.
Oh well, that changes the entire calculation.
37 km/h tops. Perfectly useable. But I won't tape off the fan of the motor.
I think the trade off is going to be weaker motors for stronger armour, whereas at the moment it's strong and fast drive for slightly weaker armour
BonX uses 2 Speed 900 with 10-1 gearratio, Sidewinder speedo, and aboutish 24V in batteries.
Armor is 3.2mm Hardox all over, with internal bracing.
The four drill motors would be the gimson 18v versions, ran at 22.2v. From my guesstimates, the four drill motors would generally be slower but have much greater torque through their 36:1 gearbox, but again the replica speed 900s will have the opposite (faster drive, lower torque). Both systems would use two botbitz 85a controllers.
Had a new frame made up. 5mm thick sides and 3mm lids. all welded steel. 4wd drive with four 18v drill motors. ran at 22.2v through two botbitz 85a ESCs. Going to change the ratio in the gearboxes to 24:1 to get a little more speed. The wheel arches will glow red in the same way my old bot glowed green. Will probably end up selling the old HDPE speed 900 replica bot at some point.
Interesting, what weight is the bot currently?
12kg without lipo and electronics. Should easily be in weight
Should make for an interesting wire up!
Would be good if you met my cousin with Cicatrix, the machines are so similar it'd be good to see how they both got on against each other
That would be cool. If not, could just have a whiteboard battle.
