Re: off road non-combat project ideas

yes you would. An electric wheelchair has wheels of say 200mm. Up that to 600mm and suddenly you got a whole lot more speed from them

Re: off road non-combat project ideas

very true, and electrocize (or how ever you spell them) 30a esc's would do it ok at 24v?

or could i even get away with 15a with 25a fuses?

Re: off road non-combat project ideas

electronize. They should be ok as long as you don't do anything stupid like try and sit on the thing. If you were really concerned you could do the external relay modification to them and run them with 40A car relays.

Re: off road non-combat project ideas

if we are talking 40a car relays, then i have found that my 15a run fine with 25a fuses so in theory i could run a electronize 30a on 40a fuses?

Re: off road non-combat project ideas

Your 15A electronize should be fine.

Re: off road non-combat project ideas

i thought that this was meant to be a simple cheap school project? I wouldn't bother trying to build it to take a person, build it as light as possible with large wheels with a decent amount of torque. Anything more and the costs will rocket.

Re: off road non-combat project ideas

true, i got a rough idea in my head involving sla's, those esc's, wheel chair motors and bike wheels

[typhoon_driver]

Re: off road non-combat project ideas

That setup should work fine. As I said I wouldn't bother trying to complicate it by making it strong enough to ride on.

and some steel box tub for a chassis with some metal just as protection

Re: off road non-combat project ideas

I was suggesting SLA's rather than NiMH's just to keep the price down, also wasn't sure on how those would work with wheelchair motors but if Gary thinks they would be fine then he knows better than me and I would agree . Also the SLA's Eric runs if used at 12v are 40Ah and to get that sort of longevity would cost you a fair whack in NiMH's compared to the 40 quid or so I spent on SLA's

@ Blazerbotics.

What does that offroader use for motors and where did those tyres come from?
