Hey Sike,
I was doing some more thinking on it last night as I was up late with a pain in the leg that would not let me sleep...
I think 2 motors for the 2 terminators is a good idea. Went back thru HC and found some of the red/blue can turnigy motors pretty cheap.
Good to know about the rpm max on the terminators. I figured that a std weedeater motor could do 15k rpm... I think a pair of cheap HC 60 amp escs on 5s lipo with 400kv motors will be the ticket for driving the blades.
I wanted some sort of bearing support for the blade shafts, just to take the load off the outrunner bearings. If this works well I plan to use it frequently and make some vids!
With my 25:1 gear reduction, 600kv motors on 4s lipo will get around 6mph, plenty fast for something like this. My zero turn mover only does 10mph and that seems too fast most of the time!
So this would be the 600kv motor that I would use to drive each rear wheel, so I would need 2 of them:

And this is a bigger motor that should do for the blades, one for each terminator, 400kv at 5s lipo is under 8000rpm:

Or I may just go down to 1 large 4s pack, like a 2-3p pack made out of 5k mah cells and run the whole deal on 4s, that would make it simpler. Not sure if I should run separate batts for the drive wheels and blades, I wonder if there would be any benefit? I am guessing the blades will draw more power than the drive wheels. Having 1 big pack would allow the bades alot of headroom should they need to pull serious current...
