Last update July 29/24
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 had 350 hours on his SDS equipped, O-200 powered Dragonfly.

SDS on O-200 by Malcolm Savill in NZ
Bert Caron did 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 acquired an O-200 for jigging and development purposes. This was used to design some new CNC'd parts to make the installation easier on these engines which resulted in our new EFI kit shown above.
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.

Some of Jim's comments:
"The results were: easy starting, winter and summer, smooth, slow idle, 20% gain in maximum static thrust and consistent, rock solid performance in every aspect of engine operation. These were previously unattainable with my stock, icing prone carburetor and magneto."
