Just a quick post on the status of my DL50 in an AeroWorks 50cc YAK. 2 gallons thru it with 32:1 Lawn Boy ashless. 3W 22X8 prop. MTW header and MTW75K canister, 80 degrees at 900 foot ASL. I get 7,475RPM. GREAT response from idle to WOT. Going to switch to Amsoil at 80:1 and switch the prop to a MEJ 22X10 carbon to lower the noise further yet. I'm much quieter than most of the 4 cycle planes and for sure all of the 2 cycle ones.

GREAT ENGINE!
