Title: Re: What do I need/cost?
Post by: Tweedy on March 12, 2012, 12:40:52 PM: servos are an ok option for drive in a uk antweight but you can spend more money to use gearmotors but you need an esc for those but they are alot faster and stronger
Title: Re: What do I need/cost?
Post by: RammingSpeed on March 12, 2012, 12:46:26 PM: Looks like I'll be buying servos, the price of gearmotors is more than I'm willing to pay for a motor.
Title: Re: What do I need/cost?
Post by: haz on March 12, 2012, 12:57:00 PM: what? 5 quid a motor?
Title: Re: What do I need/cost?
Post by: RammingSpeed on March 12, 2012, 12:58:31 PM: Really? I typed in gearmotor on eBay and it came up with motors about £70 a pop! Are they bigger ones?

I've tried these motors, and, they're "alright", but don't have as much torque as the not-so-cheapo versions. These are probably alright for a spinner, but for something that really needs the torque, especially pushers, I wouldn't reccommend them.

I would advise the following:

I think not because Vertigo made 4wd antweight robot.

Absolutely not, and the sabretooth can easily handle it.
