I am not looking to roar around the skies attempting to emmulate any war ACE. I much prefer scale flying over crazy aerobatics. At 53cc I am right in the middle of the gas power range and therefore I will be a happy flyer. Besides that, less speed will give me more time to listen to the Keleo exhaust.....Adrian at CH Ignitions made a 45 second video of my engine running on the stand. I will have to be patient and avoid rushing the build.
When I figure out how to post pics I will send along some of the build.

Oh, don't worry, it WILL fly, but just that you keep in mind that a 52 cc 5 cyl fourstroke is NOT equivalent to a 52 cc single cylinder 2-stroke, not by a LONG shot.
And ANY glow engine converted to gasoline will lose about 20% of its rated power on glowfuel. Instantly.
I am sure it will fly, and indeed, it will fly rather scale like WRT speed. Mine does, at least.
WRT weight and wingspan fairly comparable, probably also reasonably comparable WRT engine power. about 82" WS and appr 24 lbs.
Mind you, what's in the vid is about as "hot" as it gets. No wide loops, no steep climbouts.
For the first bolded: Forget about the softmounts. A radial does not need them, those things run as smooth as silk with near perfect balance and near "electric-like" continuous torque,
Second bolded: click "manage attachments" and the site will allow you to upload pics if they are on your device, or if your storage is hooked up to your device.
