The only downfalls are high RPM,and low speed.There aren't many high-speed hydraulic-drives out there.If you set up something with a Hydraulic-Motor,you could make power and speed,but controlling it needs to be handled properly or it will get dangerous quick.You would need a control-stick or pedal,that would return to Nuetral very easily,but also not be erratic.I would probably run a hand-throttle that could be set,like a lawn-mower or construction-equipment.Slight hydraulic-control fluctuations could make it very jerky.It could be very cool if done correctly,System Pressure would be the key(getting it just right could be frustrating).Do your homework and give it a try.
