Thanks for the explanation Mike. I didn't think about the transportation and storage. I can see where that would be an issue if you have a sensitivity to the stuff. My brother hauled odorant once upon a time. It's the stuff that makes gas smell. One drop of it can clear a room.
My style of flying is 3D/aero and while I did get the Tigre sorted out the gas is just much easier. For your warbird style the Tigre's would be a great choice. Glow fuel is going to get higher and more rare as time goes on. Maybe a diesel conversion is in your future :-)
Thanks, david
