Along with the's six cylinder engines, we have done a number of smaller Conti engines, the first back in 1996. Mark Snow was an early SDS user on his C-85 powered Dragonfly, accumulating over 750 hours. Justin Mace currently has 350 hours on his SDS equipped, O-200 powered Dragonfly. See more details on these aircraft below:

Fuel and spark control kit for O-200. Wiring not shown. 15 lbs complete.

Bert Caron is doing an SDS EFI installation on an O-200. With some fin mods, he was able to fit the Lycoming style injector bosses into the Continental heads.

Mar. 15/17. We've just acquired an O-200 for jigging and development purposes. This will be used to design some new CNC'd parts to make the installation easier on these engines. We'll eventually be running it on our test stand with a prop. Watch for more updates as the project progresses.

Working on prototype Hall sensor mount

Machined up some engine mount hardware to mount the engine on the test stand

Prototype Hall sensor mount fabbed up

Coils mounted in old mag position

CHT sensor mount for starting and warmup

Engine mounted up on test stand

Engine with sump, plugs, fuel pump, starter installed and engine stand support arms fabbed. BMW is used for dead weight to keep the assembly from running away.
