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
Just run regular ole 10 or 15% sport fuel. What ever you have laying around will do fine.
With the stock muffler and a 10x6, going up in nitro might get you...what.... 500-600 rpm at best ? Not worth it for about 1 mph
Just make the engine happy, and keep it simple.
