Hummingbird Update-The Thunderbolt Engine

Vic from Base Leg Aviation discusses the differences between a helicopter IO540 and airplane IO540.
The snorkel fitting mentioned in the video is a one way valve. It allows fuel to drain from the intake sump when the engine is shut down. It has a little ball in it that closes the valve when the engine is running due to the vaccum in the sump. Part number from lycoming is 75444. Van's aircraft carries them. store.vansaircraft.com/sniffl...

    You are such a soldier, to be filming one day before a significant surgery. I have no doubt, you’ll be active again, sooner than average humans 😃 That engine is a beauty to behold 🤩

    I pray that the op went well with the Gaul bladder, which produces bile acids into the small intestine, and breaks down fatty acids. No half inch of fat down the edge of a rump for you! Thanks for explaining the special oil requirements for the Lycoming "Thunderbolt" that's a first for me. 🥃🤔💡

    It just amazes me all the little tweaks that you make that the kit manufacturer hasn't thought to add - like the sump drain and the rotor brake. You think maybe they'll update the assembly manual to reflect some of your good ideas ?

    The main rotor hub design is similar to the Sikorsky S-55 and S-58 machines

    The Hummingbird is basically a Sikorsky S-52.

    What is this snorkel fitting you speak of for draining fuel? I've never seen that and I'm about to mount an IO-540 on my bearhawk.
