Hey there good RC ppl. I'm considering purchasing a machine used for grinding tree stumps and want to convert it to run via RC controller. The hydraulic control levers are where the guy's hands are in the included picture. Other stump grinder owners have done the same DIY conversion, and I'd like your advice on how it should be done. The second picture is of a DIY RC installation where 4 servos control 3 operation levers. The near lever moves up/down as well as L/R, requiring two servos, then one servo for each of the other two levers. The last pic is of the preferred type of controller. Other than these pictures, I have no idea what brand or model these servos and controller are, or how they're programmed to work together.

If anyone has advice as to how I should approach this project, I'd sure appreciate hearing your ideas. Thanks.

I think the first order of business would be multiple fail-safes so that you don't get a runaway stump grinder when something goes wrong, otherwise it's just a matter of time until your improvised battle bot goes rogue.
