Mosh - Heavyweight rammer

[mattsdragons]

Recently got hold of Yank/Omega that I will be modifying for combat, the drive train is solid and plenty of power so looking at making it invertible, armouring it up and adding a wedge. Intended as a very fun robot to drive when I get the chance to bring it so just wanting something reliable I can put it without much in the way of maintenance. Pics to follow shortly but this should be a relatively easy conversion (Famous last words but ohhhhhh well)

For anyone that knows me, the name is also very fitting and will have an even more fitting pun on it but that will need to be seen

[daveimi]

Do you have any pictures Keen to see this as I'm building something similar.

[mattsdragons]

I'll grab some when I have all 4 wheels back on it.

Rough spec run down for anyone who doesn't know:

Bosch 750 drive
Upgraded Wotty 360 ESC
Optipower lipos giving 36v
3.2mm hardox armor
4x 18inch quadbike wheels

The footprint of this machine is insane, even with 750's it will have enough power and grip to out push most and bearly fits in my shed yet alone down the pit!

[teamstorm]

Key question, will it spin all four wheels at 100Kg weight up against a wall with all that traction, if not then the aspiration of this ....

"even with 750's it will have enough power and grip to out push most"

... simply results in lots of smoke at 36v ! You're not getting any more power out of the motors than anyone else after all, so if there is all that extra traction, it's just going to make those motors work even harder. My understanding is it was built to drive around a field at speed, not geared for the likes of combat in the arena. Definitely something to check before an expensive incident.

Thought bosch 750s needed a good bit of nursing to be able to run at 36v.

[mattsdragons]

It ran on 36v anyway and can pull a land-rover no problem but I will look into it, see if dropping the voltage slightly is worth doing

[terry]

I would have thought that if the wheels got good traction the 750's would stall , what's the gear ratio and speed ?

[terry]

Just realised Matt I imaging you don't want the Bosch 750 toxic2 motors and drive system now ?

[mattsdragons]

Messaged you terry regarding that but....

Its geared for a massive amount of torque, off the top of my head it's 12-15mph but its instant speed which I am happy about

[terry]

you might want to have a look at this, its yank racing my vorza a few years ago

Whats you top end on that vorza? I have a slash and have got that to 72mph on a dragstrip aha

[terry]

73 mph with the larger motor, mine has been up to 64 with different gears but that's a bit too quick around my roads and on grass it had trouble getting the top speed. I'm happy on the low gearing with 22.2 volts, that does 51 mph gets top speed in about 2 seconds if it gets enough traction !
