I found a tank that I can modify, but I need a measurement from you on how much space there is between the engines backplate, and the landing gear leg. I plan to make the capacity around 33cc, which should be more than enough, and will install a tire valve overflow for you as well. From what I saw at the Virgil Wilbur, just about everybody was in danger of over running, so 33cc should be fine. Does $25.00 shipping included sound alright with you?
As for the glow plug, any sport plug will do as long as it's in the hot heat range. I would use an 8x5 APC for the initial run in, and needle the engine so that it just gets into a steady 2cycle. Run for about 20 seconds using 10% nitro 20% all castor fuel (although 10n 10/10 oil is ok too), then shut down and wait until cool to the touch. Do this again for another 10 cycles running the engine for 10 seconds at a time, then put into the airplane and go fly.
