My project is a model III it has had a few owners flew originally with a 582 was involved in a forced landing and was damaged.When I bought the aircraft it had a 912 in the mounts but never ran in this aircraft so I have a lot to do. I bought the builders CD from Kitfox which shows installing an IS box aft of the firewall my ignition system is the Ducati coil type is this IS box an upgrade of my system? Lots to LEARN.
