CAP'S X-56 HOTAS MAPS: drive.google.c...
Calling the Gazelle a Huey, Someone was distracted when they made this...:P That aside, a great video! :)
That IS the huey. Not the gazelle.
He corrected himself later.
Cap, Please remember to put the lights on the gauges. Difficult to see over the aether on replay, mainly I think because of the heavy contrast between out side views and interior. Thanks, Pete.
nice cap!! you're totally correct about this, the freewheeling unit or sprag clutch must keep the rotor rpm high while the engine rpm goes down when you throttled down. The main principle is that the engine can drive the rotor but the rotor MUST NOT drive the engine. I even think that when the fuel is cut off the engine dragged the rotor down a bit until the wash speeded up the rotor again. Bug I guess, big one though.
Copy thx
This video is accurate. There's a review from a real Apache pilot on the DCS Huey and he said needles should split by throttling down and they don't in the Huey.
9:20 - Mi-8 has a fuel cut too - two big red levers on the ceiling.
12:50 - fuel cut in Ka-50 is two big red levers on the left console, besides the collective.
14:40 - radio-altimeter warning of crossing preset height

Super Cap is truly a man for all seasons.
11:08 Cap I recently bought the Gazelle and initially felt the same way about the handling, way too twitchy and hard to fly. I looked on forums and found a huge help was setting the Y saturation to 85 and curve to 15 on both pitch and roll axes, makes handling it so much easier. Also, setting the trim once you’re in forward flight is a huge help.
will try
Is this a bit like when you stop moving the pedals on a bike?
Exactly
Yup, bike has a simple ratchet clutch.
yep it's called a Sprague Clutch on a helicopter.
it is exactly like that
Why pitch down in autos? Pitching down makes rotor rpm to drop (while turning makes rpm to rise for a giroscopic effect), in real autos you have to pull back a bit to mantain rotor ‘s rpm and mantain around 70kias in most helicopters models.
Just bad habit I've picked up
The cap is not pitching down, the Huey pitches down due to a very very old bug in the FM
It's been a long time since I twisted a wrench on a helicopter but I don't recall any mechanical clutch on a gas turbine equipped helicopter. Probably is one on a piston driven heli but I never worked on them.
A gas turbine uses two stages: a gas producer and a power turbine. The second is connected mechanically to the gearbox. The only connection between the 2 is fluid, i.e. exhaust gases.
Still, because of the greater inertial energy in the rotor head, the gas turbine should show a decrease in rpm before the power turbine/rotor system.
There's a clutch in all the helicopters I've flown. Being able to disconnect the drive system from the rotor system is critical.
we are talking about Freewheeling Unit, like in a bike. Every helicopter has it, otherwise FAA wont approve. BST isn't modeling correctly the engine in this and a lot other aspects.
Right... let myself get hung up on the clutch term but that is what the fwu does, I suppose.
@@WebberAerialImaging actually no, the free turbine is linked to the driveshaft
I just noticed... The KA 50 has the same generic wind-up clock as in the Mig 29. who would have thought.???
cool!
they are not generic. It is just common clock type for many of Russian aircrafts (czcams.com/video/p2DTEcq5aJ4/video.html) AСhS-1 or AChS-1M, they are similar.
It looked to me that the k50 didnt work correctly. The rotor did drive the engine.
Hey hey! The Ka!
Lovely chopper it is, and lovely video too!
Cool review man !!! Thnks
Keep up the good work sir..
IN Gazelle, you can disable the cockpit shake in the Gazelle options...
cool
I'm fast as fugg boiiii
I practice auto's all the time in DCS by rolling the throttle to idle. I always get a split. I recommend a repair on your install.
first you need to understand what a split is. In the Huey the only split you get is when fuel is cut off or engine fails. But not when turbine rpm is less than rotor rpm like IRL.
@@piston_77 You and Cap are correct, just rechecked, and indeed the N1 stays matched up with the Nr when you roll the throttle to idle. I must have been thinking about my auto practice in Xplane :). That's Ok, the auto characteristics in DCS aren't that great. That nose tuck is absolutely not present in real Huey's on entry to the auto, but it's still a blast to play around with.
@@drussell15 you're are right about the nose down tendency when engine is lost, the Huey is very fun but still has a lot to improve.
@@drussell15 nose tuck imo is just da Grim trying to get some airspeed for saving rotor rpm in the safe zone. this is not Arma on BFM, you can't land here just vertically on autorotation. ^)
you are not trading potential energy for kinetic energy in a dive when you disconnect the rotor. It is not a jet. You are having no connection to the driveshaft and now the air is the only thing that drives the rotor, which is done by increasing or decreasing airflow through the rotorsystem, or basically getting the air in a certain angle of attack through your advancing and retreading blades. That will increase or decrese the blades and eventually split the needles.
Roger I think I understand.
actually no, needle split should occur due to a Freewheeling Unit that all helicopters have. Like a bike
how did you get the hud screen in the ka50 to be english. i have the cockpit set in english but the display is still russian
is it an option in the "special Ka-50" menu?
@@grimreapers ill have to look again, i didnt see it. Thanks!
Si you helicopther possesed thechnology nessesary to pull out helices and give you eyeccion to save pilot the human real cost more considering option used
