Sounds daft but for Ricochet could you split out the servo cables and use a second XXL etc? Would allow you to keep the robot as is if you're happy with it.

It could work provided the ESC's don't share any motors between them, if they do it might get a bit toasty :PQuote:

just swap the motors???
It needs new gearboxes and a new chassis anyway. It works (just), but it's tired and I want to see how I can improve on the design. Plus I'm looking to at least double the speed, 6mph is a bit on the slow side for a drive based robot.
I'd give the Ragebridge a look. I've been running a pair of feathers with Ragebridges and 18v Dewalts and they've been quite happy.
http://e0designs.com/products/ragebridge/ looks awesome!
But I get what you mean about it being a good time to move on and build something else. I'm always looking for similar excuses to build stuff lol :)
I think its more cost effective just to replace the motors with the spare ones you've got. I know the gearboxes may be a pain but there are ways to fix that and get your speed and power back without spending anything.
Flow had a good first day at Maidstone, survived both fights despite the valves not being wired up. On the Sunday however, after I tested the pneumatics to discover to my surprise that it all worked fine, I found a brush casing smashed on one of the motors. Tried to bodge it back together with tape and glue but it wouldn't hold so gonna order some replacement cases and get it running good for next year. Also discovered I only had to lose 200g, and after taking 130g of HDPE blocks of the front I'm left with only 70g to lose and 5 months to do it... She will run at the champs :D
Next event I believe is Ally Pally 2015, so see you there if you're going
Gassed her up and did a quick test with the manual valve switches. It's finally working, and somewhat reliably too if you can believe it!

Damn it, I was just hoping you'd break down in our first fight so I'd only have to worry about Endeavour :p
Yesterday Dave helped me get the left Astroflight back in working order after it shattered a brush casing, now it works but occasionally stops at a specific point on the motor. We've checked, it's always the same point when rotating the motor shaft that it sticks at. If anyone can shed some light on any reason as to why this is happening, I'd really appreciate it!
Grant said that the new brushes might need wearing in, it seems to have lessened the problem but it's still there and occasionally the robot goes to drive forward and veers off to the left :P
Anyway, here's a video of it flipping a microwave around with precisely sod all gas in the system:

The only time I ever had a problem like that, it was caused by armature damage, which is hard to find and repair. I still have some Astros left if you need a spare.
