This isn't really about racing, but I figure that if anyone knows the answer it should be you guys.
For the Ringmaster Fly-A-Thon I had the notion that I'd just put in as many consecutive flights as I could manage with one guy on the handle: short-tank, start, fly, shag the plane, repeat. But with an FP-20, it turned into: short-tank, start, fly, shag the plane, go shoot the breeze with the RC guys until the engine cooled enough to start, repeat. Instead of my imagined "lots" of flights, I think I managed about six in the two or three hours I had available. I'd like to do better next year.
I have, in my collection, an FP-20, a couple of LA-25's, and a couple of old OS 25Ss. They all bolt onto my Ringmaster, and I've got at least one good engine of each type.
Which one would be best for my imagined flight scenario, and what should I be doing with fuel, plug, battery, whatever, to make sure that restarts are as quick and as sure as can be managed, and that I don't damage anything?
TIA.
