Brian, that IS the point.
Perhaps the conversation would not have started off on the wrong foot if the loaded word "rigged" had been avoided. The F2C fuel tank volume rule essentially dictates that you must run a diesel, based on known and existing equipment development. However, if you doubled the tank size, then existing glow engines would be competitive. In fact, we used to see a team run an F2C diesel rig with a 15cc tank in our .15ci Rat event run on 60' lines. If the glow entry got even a semi-decent restart they would win because they had them on speed. It they didn't do well in the pit, the proven F2C equipment, although slower, would win. That made it a fun race to watch--or be in.
I'm not dogging on the F2C rules. They are what they are. But it is a bit ummm, unrealistic, to imply that the current rules for F2C aren't tailored specifically to the use of diesels. No one has to come out and say in the rules that glow engines are prohibited. On the other hand, it might really make a mess of a race if someone took a good .15 Rat, put it on 15m lines and marched out to the circle when called. Of course, we'd have to assess the venturi rules too....
As far as Floyd's questions on fuels, I sure wish I could just go to the hobby shop and buy a liter of even a sport diesel mix. Getting the ether here is a pain.
