I've been kicking this around for years and said I would do it when I owned my own house. Well that's been over a year know, time to get started.

I see most DIY RC mowers using wheel chair motors with complicated logic boards and motor controllers.

I'd like to stick to what I know. What I need help with is knowing what size motors I need, KV, and gearing.

A 15mph top speed would be more than enough. Mower probably would weigh around 50-60lbs?

I was looking at these motors at Hobbyking. Maybe with a pair of these esc's. I actually have a pair of MMM's I could put in there, but whatever.

I know I'd need to figure some gearing out. Potentially a chain drive a with some sprockets.

Maybe I'm crazy, but I think a pair of those motors could easily handle it considering a single 2200kv CC motor can power my 15lb Savage to 50mph. As for batteries, that's no problem. I'd just put a ton of lipo's in parallel for run time.

So, anyone got any ideas?
