Fuel ???
Ok guys, so im finally ready for my maiden flight of my Cermark F-20 Tigershark. I currently have an OS 40 FX w/stock a exhaust on it, a MAS 10x6 prop and i was wondering what fuel (10,15,20,30%) to run in it to get the most out of it but not burn it out. If it matters any im at 305' ASL in ontario canada
