    P-51C at ~70% scale as ultralight?

    I created a Facebook group called "ULTRA LIGHT P51 MUSTANG (FAR Part 103) ". Take a look! I found and posted pictures of an actual flying half scale P51 (trying to entice you).

    Polaris ProStar Engines? 45hp.

    Hey WBNH, I just stumbled onto this same line of engines, hoping I could use one in my Ultracruiser. Unfortunately, it looks like they are just too heavy. A Prostar 400 longblock, which makes around 29 HP I believe, weighs 79 pounds, without carb, exhaust or any other bolt ons exhaust a very...

    P-51C at ~70% scale as ultralight?

    Thank you Kevin. I was thinking I would swap in Ultracruiser wings, maybe redo just the fuselage skins in lighter aluminum like the ultracruiser, and with a 30lb 2 stroke engine (ZDZ500), I think I'd be okay, but it's a lot of work/changes

    P-51C at ~70% scale as ultralight?

    Yeah the plan would have been to do an 80% scaled down RV-3 fuselage with 2 stroke engine and Hummel (part103 compliant) wing and probably tailfeathers.

    P-51C at ~70% scale as ultralight?

    Hi People, Newbie here, thanks for letting me join. I'm very interested in this thread, as I am currently planning a project nearly identical. I have purchased the plans for a Hummel Ultracruiser, and am planning to modify the fuselage to look more conventional, similar to a P51D but probably...
