I weighed the VW engine from the Sonerai project,  for comparison to the single rotor weight later, and figured the other single rotor boys might be interested in what a 2180 VW really weighs.  

 

- Great Plains 2180, Diehl case, 1’ exhaust pipes, short intakes on heads, secondary ignition, force one prop hub – 150 lbs

- Spacers to mount Diehl case to airframe- 4 lbs

- Starter- 11 lbs

- Magneto- 5.5 lbs

- Stock oil cooler- 1.5 lbs

- Zenith carb and horrible adapter- 4.5 lbs

 

Total weight above- 176.5 

 

A carb mount, and tubing to connect the carb to the intakes on the heads, plus oil would have to be added, along with coils and wires for the secondary ignition, and baffles for cylinder cooling.  Realistically, this would end up weighing around 185-190 lbs with all that added.    Power is rated at 70 hp continuous, and 76 hp for takeoff.
