He is out for the moment, but not for ever
I guess he's too busy cruising in the 60's Caddy he bought...
I haven't mix the ESC with the valves (yet
) The pump is turned on and off from my radio. I guess mixing is more useful on loaders, since they are driven quite alot without using the cylinders.
The tracked loader is sold btw, Would've been nice to keep it, but it was too much money tied up in R/C equipment.
