Re: large scale RC
I was thinking about a variable displacement pump and a motor on a custom rear end with like ford 9" differential guts in it. The pump would be just like the ones in a skid steer, only one section, this would give fwd, rev, braking in a closed loop system and a cushion valve in the motor lines would give emergency braking
Then it's just a small hyd pump for the bed dump, steering motor, and shock adjustment.
I'm thinking the drive motor would be a 2 speed motor for speed range, but the pump has the control for actual speed adjusted by a servo. Thus I would have 2 speed ranges fwd and rev but still infinatly variable in those ranges by stroking the pump in or out, plus have engine throttle adjustments on top of that yet too. Thinking a 3 pos switch on the radio could easily be rigged to run the engine at idle, mid idle, or high speed.
