I picked up a Spectrum from a guy that is 85% complete. The only problem is its outfitted with pneumatic retracts and I have no idea on how to complete the installation. Is there a place that shows how to plumb the retracts. There is no indication of a manufacturer on the retracts or valves. There appears to be a valve that is connected to a servo. But there are no markings on the valve as to in/out or up/down etc. If someone knows where I might get a schematic or something I would greatly appreciate it.
Thanks
