I have approximately 3,000 hours as an instructor in the R-22 and I have found it to be a very reliable and durable aircraft when flown within its limitations.
I have done more full touchdown autorotations
in them then I care to think about, and all of my students are still alive and well and some have even gone on to fly professionally.
Most people who have never flown an R-22 for more than 30 minutes, haven't had the chance to fully appreciate its capabilities.
They are a good aircraft. I fully agree. The governor is money as well.
But, they have their flaws. A main rotor governed to 104% tells you what you need to know😂 in some ways.
Semi rigid in plane, free to teeter and cone.....well....at least we don't have to worry about ground resonance right? 😂😂😂
Jokes aside, there is a movie out there called the Robinson R22, and, it's a bunch of new zealanders putting it through their paces.
Basically tore chapter 2 out of the POH. I imagine them riding the LOW Rpm light while under power like a surfable wave and, making minimum fuel missions for their deer-slingline operations at altitude. They were next level with it. Very cool.
I personally might have some reservations about flying something so small if I did not see this video beforehand. I really was impressed and the pilot does a first rate job of demonstrating not only his expertise and technique, but clearly demonstrates the capabilities of this little machine. Well done and well presented indeed!
Yes, for what it is worth, I do fly helicopters for a living, but I have never flown one that was a homebuilt or kit type such as this. It sure looks like great fun!
Great demo flight. Thank you.
Wise man. Practicing those autos!
wow. the 20ft hover autos are intense. i hate having to do them at all in the R22. Awesome pilot.
an autorotation is when the rotors are disengaged from the engine and instead of being turned by the motor, the rotors are turned by the airflow traveling through the rotor system as the helicopter descends.
Amazing handling
Wow, that's really impressive for such a tiny little helicopter. Very nice flying! I wonder how it compares to the R22 in terms of inertia-- I doubt I could do some of the things shown here in a 22, but maybe a more experienced pilot could? Very, very impressive showing for the little Mosquito! Makes me want to try one!
Very impressive John. Haven't seen that much control over one of these things. Allmost makes me want one! Can't get over the threat of sheading parts in flight though. Ballistic chute would probably sell me!!
Well done! It sure drops quickly in an autorotation.
I think he is dropping som collective for the TALL autos. Nearly OGE in some of those chops
this guy's a helluva pilot. wow!
@Mlagersson "Autorotation" can be either from air flow or rotor inertia. If the engine fails in a hover, it's still "autorotating" from inertia.
Impressive autorotation.
That was Awsome!
Thank you for sharing. I am researching ultralight aircraft and found this video. Very impressive. I would have found it more informative if it had been filmed from the other side, so we can see the pilot operate the collective.
I am very impressed.
Very Nice! I want one.
The ability to do an auto from 20 feet agl from a hover speaks volumes of the blade inertia. There are very very very few heli's I would even think about trying that in from that altitude. And I am talking some expensive rotor craft.
You are a beast.
SERIOUS SMOOTH!!!!
That would be one crazy lawnmower!! sounds more snowmobile-ish to me.
The R22 is a great helicopter at sea level. When you get up to 5000 feet with a density altitude of 7000 feet you tend to rethink your flight options.
Yep out of reserve. Wanna say 131 hp at 5min limit with -7hp per 1000PA on a standard day.
Let's see 180-131=49HP in reserve at MSL.
49HP÷7Per 1000'pa=7'K PA
so yeah 5000 indicated with 7kDA. Not doing much climbing😂😂
He's a commercial airline pilot,but his dad had a chopper when he was a kid,and started him at an early age.I think on the fullflap interview he said about age 11?
Mlagersson is correct, and nocalsteve and dropkickmurphy01, you are wrong. Autorotation only occurs when induced flow from above ceases and is replaced by air flow from underneath. Hovering autorotation is a misnomer. See Principles of Helicopter Flight, chapter 18.
Haha, "Look ma' no hands!" All hail King Snider! =P
I know these are built safe but that's really impressive.
Awesome
how many hrs did it take him to get tis good?
It's a nice little helicopter. Was thinking about it until I saw the price tag of $30,000. Maybe $10,000 is more what I thought it would run rtf, even with a rotax.
how do you get the training to fly it if you buy one??
How much is one? and where can I get one? this thing is cool.
I want one of those!!!! an R44 would be nice too... hehe
@MosquitoAviation how much is the helicopter in British sterling please? and what is the range on that helicopter? does it use aviation fuel or normal petrol?
Ground resonance?
Does anybody know if this carries enough weight and wing surface to perform a successful air flow auto?
whats the engine from a lawnmower. good flying :)
What kind of range does this have??
this is not a reflection of this helicopters h/v diagram because he is lowering the collective when he rolls off the throttle. the low hover point on the h/v requires that you don't lower the collective. still very impressive
I live in a really wooded area and am concerned about having a clear area to autorotate to. Lets say I am flying along at 700 feet and motor died, I have a location directly below me. Would I be able to drop collective and stop forward momentum by pulling up on the cyclic(instead of 360 maneuver) and still be able to build enough energy to pull collective at the bottom?
No, if you do that, you will not have sufficient air coming from underneath the blades to keep RPMs up. You could probably spiral down though and generally stay above the same clearing while keeping the air moving!
burlbark I'm not sure about this specific helicopter (never flown one), but probably you would need some forward airspeed to make your landing survivable. The only helicopter I've ever seen that advertised the ability to make a survivable landing ONLY by pulling collective at the bottom is the Cabri G2, and even then that's not a claim I'd like to put to the test. Generally you need kinetic energy in the form of forward airspeed to perform a flare at the bottom that will arrest your decent rate. If you're flying over an area where landing spots are few and far between, just fly a bit higher so you have more time to react and more glide distance to get somewhere useful.
Having no option the best would be to lower collective to full down stop, arrest forward speed by aft cyclic and then arrest rate of descent close to ground height depending on rate of closure to the ground. Oh and ofcourse say your prayers in between. Better than crashing in trees
Have done zero speed autos from 500 feet. You require some forward motion at the end to execute flare
I wish we could see his collective hand
Sounds like my damn pocket bike!!.
What is a hovering autorotation? And when would it be used in flight?
Thanks.
ajcrm125 when hovering 2-4 feet off the ground. In the event of engine loss. You would do a hovering autorotation.
Hover auto does not require airspeed. Ground effect and collective pitch arrests your landing
I like it but NOT with a 2 cycle engine in a helicopter application.
Yes, I understand that low weight is critical in this category aircraft but so is proper lubrication of hi speed moving parts in the power-plant of an aircraft, especially a little helicopter.
It cost around 30,000$ !
unassembled, they cost just under $30,000. if you have a heli pilots license, you get about $2,000 off the price. You can order it pre-assembled, but i believe that costs an extra 5 to 6 thousand.
Also:
Correction - The narrator calls a 70/90 degree left turn auto a 180 auto toward the end of the vid.
Considerable difference in the demands of the pilot n aircraft IMHO.....
Well, technically there is no such thing as a hovering auto. Induced flow does not drive the rotor when you loose an engine in the hover, you just have to use the inertia of the rotor system to cushion the landing.
well apparently he is not talking -_-
so i was watching Daily Planet (show) and it showed this, and this actually supposed to be very easy to fly, it only has like 6 controls
nearly blowing tail rotor while almost landing
Why don't helicopters use wheels with shocks/struts instead of stiff skids?
VTOL... wheels are pointless, if anyhing the only other landing gear you might need is floats. Some heavy helis do use wheels but only to make it easier for them to taxi around like on an aircraft carrier etc...
Helicopters often have shocks and wheels. (Blackhawk and Apache for instance) They are needed for rolling take off and landing (high DA, and or high gross weight.) They are also important for some emergency procedures such as a fixed tail rotor pitch, etc.
The additional risk comes from an issue called 'ground resonance' which can easily develop in wheel and strut helicopters under less then ideal landings.
Sounds like a lawn mower...! This guy must be either super brave or super D....!
research him ! he is one of the best designers and re-designers on this planet , plus its was a brilliant concept that lets anyone afford a helicopter .
Wish u weren't talking so we can hear what he's doing with the throttle.
I presume that engine was fully warmed before going to full power.
Doesn't matter...it's just a 2 stroke
Sorry, but it doesn't count when you start descending before you cut the power. The FAA requires a full 1 second delay between power cut and any collective movement in standard category certification testing. Obviously the whole point of being able to autorotate is incase the engine quits. And when the engine quits I doubt you are going to know about it before it happens. Now try it without cheating...
8:37 tail almost touches ground
Reason why there's a tail bumper
9:02 - no chance
I'm a total helo noob. What's an 'auto'?
I wouldn't buy an r-22, which has nothing to do with price. eek.
Thats not an auto. Thats just a throttle chop.
but he didn't
Nope. Your wrong. Hovering autorotation is NOT a misnomer. Autorotations inclued a loss of power...correct? So if you are hovering and lose power you autorotate to the ground trading rotor rpm for lift, being in such close proximity to the ground. So, no. A hovering auto has nothing to do with air flow from below. I.E., you have your 890 RPMs at 20' agl, you lose power and start to fall. You then pull pitch, trading rpm for lift, thus saving your ass.
machtuck11 You end in a hover.. duh
Death trap...
I think most of the 3 deaths seem to have been due to hitting powerlines and medium altitude flying (including John one of the main engineers sadly... essentially pilot overconfidence not any unrecoverable hardware failure, note John had survived an experimental tail rotor failure a few years ago also but that hardware was never in production)... that's not to slight John but humans are prone to failure. I think a HUD with marked areas for takeoff/landing and only flying at very low or higher altitudes this would be a very safe machine Also, I don't think this is really a full auto rotation, more like half of it... as part of autorotation is maintaining rotor speed during decent so you have enough inertia to use ground effect to cushion the stop of the helicopter and land, this does not demonstrate the high altitude part of auto rotation.
Its not that much compared to some cars
he don't bother me any. just another child on here trying to act like something he's not. i ahve more time in rotors then he has, and i am not even licensed for rotors. fixed wing time, 3,500+ hrs. As for cw3... well, look at his little vid's. he isn't even old enough for cw3. cw1 yes, cw3, he's has 5+ more yrs to go. cheers
I own a C182 and an RV6. Have 1,900 hours, ifr, twin, and light jet. Stick to your rookie copter and stop bashing others. RC. My toys cost more then your car. Cheers
Actually, I don't think you own any of the above, since you just had to work in that you own 3 expensive vehicle as well, just to boost your ego a bit. Stick to your fantasy land and I will stick to my fixed wing aircraft. As for this video, an ultralight rotor wing aircraft is pretty cool. Which if you know rotor wing or aviation even in the slightest, you know what an RV6 is and would have mocked it too, noob.
I've owned three R22's and they were all great helis.
Somehow I doubt you'll ever have to concern yourself over buying one. Stick to your RC's.
Hes going to destroy his helicopter doing low level autos. That is just asking for trouble.
must be like zero durability on that poor little engine, it has to scream to get that thing airborn, getting that thing airborn would be like driving my car 100mph all day. engine size and gearing is totally wrong!
I don't believe none of your shit!!!! LOL
You claim to own a Lambo and a Ferrari but then you only upload a video of an old Mitsubishi Eclipse on CZcams. LOL
Whoppeee! You own a Cessna and a "model/kit" airplane.
How many hlicopters do you own? LOL
Ps
No, your toys do not cost more than my cars.
I own a Porsche, a 740IL BMW and an H2 Hummer.
If I were you I'd find out who I was replying to BEFORE I replied.
And I own an R44 Robinson as well.
Go back to your cheap planks.
