there is already a hydraulic system made for the 1/5th hormann ht2 to convert it to a 4wd car (i have pics somewhere) was only a prototype though (fluid is pushed form the clutch bell through hoses to the front hubs then back to the clutch bell/pump).

we already have ecu's for the petrol cars (advances the ignition advance and runs of the power created by the electronic ignitor modules and allows you to alter the timing advance to suit) i cant see nitro being a viable option for to much longer, im surpised no one has made a mini 2 stroke multi port petrol engine yet with its own ignition system like the zenoah/cy, would save most if not all the fueling issues and running issues with them.
