very helpful thanks

and thank you for your knowledge .its appreciated

thank you for the tip

A couple comments... The real reason helicopter pilots practice autorotations is because they're so much fun!!! A couple people commented about the amount of ground slide... Without knowing anything about this particular helicopter, I can call out two criticisms of that auto... First, it looks like he entered the flare going too fast... You can see how long he floated before touchdown. The other was the minimal flare. It really looked like he just leveled the aircraft rather than flare it. The result is exactly what you see here, a fairly fast touchdown and a long slide. Given that he was landing on a runway, not a huge deal, but off airport where things are often pretty rough, it increases the chances of tipping over. Someone asked about coming back on the stick after touchdown to decrease the slide. That's not a good idea, because as the rotor rpm decreases, blade flapping increases. Tilting the disk back at that point often causes you to chop off the tailboom. Generally you want to do your slowing down while you're in the air. Once you touch down, you don't generally want to move the stick forward or backwards...

very well presented . this one of the best on the internet

Apologies for the comment I inadvertently deleted. The aircraft spruce part number for the heat barrier is 08-00600. It is $27.50. Vic used 4 for the lower cowl on the RV-10.

Maybe it’s just an artifact of the video, but how did the inside of your cowling get its copper color?

Very good advice, as usual. I got exactly what Vic describes, some blistering on the paint. I added some heat shields on all the exhaust pipes that are anywhere near the cowl - seems to have helped. Adding the layer of aluminum shielding on the cowl looks like a good idea as well!

Do you remove the jumper from the ignition switch if you swap the NON-impulse coupled mag out for a P-mag? Ie: I have a standard mag with impulse coupler on Left, and installing a P-Mag on Right.

How about using Fiberfrax? Less weight, thinner so it will form to the shape of the cowling and a good heat insulator.

The biggest problem with worm style hose clamps is everyone wants to overtighten them. This damages the hose, makes it less resilient and then the clamps tend to loosen over time. A properly tightened screw style hose clamp will work as well as any other clamp and last a long time and can be removed and replaced in the field with common hand tools. Either use a torque wrench on the hose clamp, which nobody does, or tighten until the clamp ring is just flush with the hose surface or a little less. I often will use a torque wrench when using a new style clamp or a new style hose and see how much the clamp compresses the hose. Once I know that, I can then tighten with a nut driver or screw driver and be pretty close to correct without the need to use a torque wrench.

Thanks for sharing these videos Vic. They are super helpful to this first time builder :-)

Could you plz make a video removing and inspecting the fuel inlet filter of the carburetor.

Thanks Vic. I noticed you mentioned the constant pressure clamp on the intake hose but not on the valve oil return hose. Was there a reason for this? I recently replaced my valve oil return hoses and put a constant pressure (spring) clamp on instead and it is sealed a lot better now.

You mentioned wrapping your fuel-flow Red Cube in heat-reflective material. Do you have a part number or source for that material? Love your videos!

G,day from Sydney Australia. What are the indicators that rubber engine mounts need replacing? 🌏🇦🇺

How do you feel about applying Niel seal (Spruce) to each side of the intake gaskets before assembly?

Thanks Vic. For those of us that are building and never really owned much less maintained our own airplane, these videos and your books are invaluable!

Great Viedo! Thanks

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?

I just had a mixture cable like that break 2 months ago at 10,500’!!! I went with a twist set up.

Whirlwind on my RV6A

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?

Make a tubine

Did you mention cruise speed?

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

Is this the hummingbird that crashed recently?

05pretty cool helicopter.. I noticed you pulled the stick back on touchdown ( 20:05 ) is that a difference to most helos with skids?

Really informative. Demistified magnetos for me. Thanks for posting!

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.!

Question: If the weights are to be put onto the flywheel, then why is the rotating mass of the spinner not included?

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.

Great video!

I saw a lone Stearman flying to what looked like PDK today viewed from I-20 on the east side. Probably one of your guys.

I watched you guys takeoff from mallards today. Looked great.

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?"

Beautiful aircraft. I hope you enjoy the upgrades

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?

get Vic's maintenance manual! very useful

How would this perform at 10,000 feet high home?

Thanks!!!!!

Love it GREAT TEAM!!!!!!!!!!!

Carol telling you which way to go... well she is the GPS, (Girl Positioning System). 🙂

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.

Hi Vic was a pleasure to meet you yesterday at Sun & Fun !

Nice helicopter!

Walked 🚶‍♂️ by beautiful ship

Well you said you was worried about the weather stay safe!!!!!

Great video. Can you do the static run-up with the spinner off?

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.
