- There are no model engines available with less than 1.5 cubic inch
- displacement that do not use oil in the fuel for lubrication. There
- may be some very large model engines (Kavan?) that have a separate
- oil systems, but it is not too practical as the engines get small.
- You need some way to get oil to the valves and top end, typically a
- pump is required which adds to the complexity and weight.

- Burn fuel that only contains castor bean oil. It should be bio-
- degradable since it comes from a plant.

- Have you considered electric for indoor flight?

- Yes, any 4 cycle could be modified for separate oiling system. The
- major advantage would be longer engine and bearing life.
