Vic Syracuse from Base Leg Aviation a company that provides maintenance for amateur- built aircraft shows problems found on inspections and how to repair. He also provides building updates on his Hummingbird helicopter build.
I still have some confusion about this. If the pitch stop is designed to prevent excess RPM then why would the governor come into play to keep RPM below 2700?
You want to keep the prop from overspeeding at full throttle, such as during climb. Basically, you set it up to act as a fixed pitch prop and then let the governor take over at 2700-2720 RPM's. IF you have the governor taking over too early, then if the governor should fail, you will have a massive overspeed, sometimes necessitating a tear down of the prop.
which mixture cable are you talking about? All of the engine controls on my RV10 are high quality ones with threaded ends and rod end bearings, the same as any twist control.
@@baselegaviation1614 it was the one that looks like a piece of welding wire like the one shown in your video. Briggs and Stratton lawn mower set up basically.
Great video! I’m having a hard time finding a mechanic to diagnose my injected engine. Like it’s really bad. You on the west coast at all and able to help? Or can I pay for your time to diagnose?
@baselegaviation1614 I see the one that crashed is using an LS engine variant. Any idea of the cause? NTSB said it was a 260L that crashed, however if it was a V8 version it would be the 300LS model technically wouldn't it?
Vic, great video, presentation and content!! I have owned several helicopters and am intrigued with the Hummingbird with its Sikorsky DNA. Compliments to your assistant Carol for some fine camera work too.!
Thanks. Glad you enjoyed it. Yep, we wouldn’t have these videos if it wasn’t for Carol. I think she missed her calling as a Hollywood Director. You wouldn’t believe all the retakes I have to do!🤪
Of all the aircraft I would own, if i could, the Stearman is number one. Keep your jets, your obscure warbird whatever types, this biplane radial is my first love. Sadly I know I wont be in the position to fly one, it remains my favourite nonetheless.
Just replaced my sender with an new one. How long to wait before adding gas? Looks like the b 1/2 proseal is cured to tack free at less than 4 hours, and 35 A durometer at less than 7 hours. Is there a utility in waiting days, or is this just a practice people have adopted over years to be "safe?"
I don’t think I would do an overhaul… Do an IRAN or reseal, but a full on overhaul where they grind the blades isn’t necessary and takes life out of the prop..any thoughts on that?
Thank you for the HummingBird videos, I build an RV-10 with assistance. I am considering the hummingbird kit. Do you think it would operate well in the rockies? Our home is in the mountains is at 9,200 elevation.
call Brad Clark at Vertical-Aviation. They did high altitude testing. while I think it would work well, I haven’t flown it that high so I have no experience upon which to base my answer to you. sorry.
Thanks for that report. EAA/alphabets at SnF, Oshkosh, RAR never post true data about what is happening, especially with the weather. It's always sunny, birds are tweeting, record attendance -- all the bits and pieces of corporate interest support.
Thanks so much Vic! I’m getting very close to finishing my RV-14A and your recent videos are so serendipitous. I’m looking forward to putting your words of wisdom into practice. BTW, you are responsible for my decision to build, you answered my multiple questions at SNF 2108 when you with Van’s and started me on the journey!
@@baselegaviation1614 Excellent…yours is a beautiful build. I fly an Enstrom but would love the extra room your Hummingbird has. I’m simply not patient enough to build one! Happy flying.
Thanks Vic, really appreciate your maintenance manual which contains critical information about maintenance and repairs on RV’s. I’m very satisfied with my purchase. Happy Landings 😊
I got the SL, and then read manuals 159 and 193 for reference to my Mattituck O-360A1A (mag and LightSpeed) and attached Hartzell HC-C2YR-1BFP with F7496-2 blades. I'm basically outside their compliance parameters because I had 9:1 pistons installed, and did not have an overhaul performed but rather an IRAN. Sensenich deemed the prop in excellent condition, partly because the plane has been hangared all of its 1595 hours; the IRAN of my PCU5000X also resulted in a "outstanding shape" report. The SL provides good-to-know stuff at this point, maybe fair warning to be on the lookout for any issues. The statement in vol 2 of manual 193 "a small crack initiation can propagate into a full failure very quickly; in some cases within a single flight" is flat out alarming! There are no guarantees of safety in aviation.
