Hey guys, new to gas and have two flights on my DA50. The engine has about 5 gallons through it, and I am running 50 :1 Amsoil in it right now. It will swing a Menz 22X10 @ 6250 and a MSC 22X8 at 6900. This is with a Bisson pitts.

Do these figures seem about right?

Also how much would I gain by going with a Stock muffler? And lastly what could I expect a Mejzlick 23X8 to turn at?

Thanks Alot!!
