Hey iateryourcheese,
That sounds very interesting.

I have read about the veggie van runs on homemade biodiesel from fryer greese, but did not know that would work in model diesel.

Recently I made some model biodiesel by replaceing the kerosene portion with lamp oil (smells much less) and the lubricant wioth filtered peanut oil. Though I haven;t flown it yet, the engine runs great with it on the high end. Just idle funny, but seems solid though.

Did you have to add anything to your formula to lower the flash point? Otherwise the compression in model diesel engine would not ignite it.
