Have you been looking for an an honest to goodness BIG four stroke radial GAS engine? Well... you JUST found it!

The RCS 250 is supplied with an electronic computer controlled auto advance ignition. This ignition is rather unique, as the high voltage coils are mounted in the rear of the engine and the control unit connects to them with a multi-pin connector and only low voltage DC current is conducted in this cable. Each plug has its own high voltage coil so; there is no need for a pesky disributor. The timing sensor is also located inside the engine. The net result of this great arrangement is a neat installation that is quite compact. The ring collector exhaust system, shown in the photos, is standard equipment.
