Holm und Rippenbruch!
a good and crash-free flight

Huge respect for building such a special kind of a Chopper!!! 🚁👍🏼
Like all helicopters, it doesn't actually fly - it just vibrates so much that the earth rejects it.
Hilarious!
LOL, i am suprised no one got r/wooosh here
Yes, he's using swashplate instead of servoflap and twisting blade (a complication that's probably extremely difficult to replicate at this scale) but hugely impressive. Looks, and seems to fly, like a real K-MAX. Very cool.
I use to work for Kaman and worked on the KMAX
@@jimdoiron4267 I used to be a rotorcraft instructor in CT and we had a chance to tour the facility back in 2010. Everyone was super nice and the aircraft was amazing. They brought one to the school once and we had a chance to poke around it, and see it fly. It's crazy how low the rotorspeed is, and how quiet they are. The flight control system is fascinating. And I especially like that the blades are spruce...old school tech.
love the KMAX! nice!!!
I used to heli log in British Columbia using a Kmax back in early 2000,kudos on this build 😎
That was so cute when it hoisted the tree branch
I worked at South Rim Grand Canyon in 2009 when a K Max was brought in to remove wreckage from a guest who purposely drove over the cliff. Ever since I have a fond appreciation for this small craft and it's ability to lift objects up like it was nothing.
Extraordinaire
Awesome, my favourite machine. Well done piloting also, great vid
One of my favorite helicopters (also CH-47). No servo flaps on the rotor blades? Does it use a swashplate instead? Amazing how full scale version can fly without hydraulics.
not much out there about the design of the servo flaps but by the looks of what i could find its not a simple system and to make such a complex system on a small scale would be a pain in the ass.

The full scale kmax does have swashplates, the links from the upper ring of the swashplates go to push/pull rods inside the blades that move the flaps rather than turn the whole blade grip. Left/right cyclic is only applied to one rotor disk or the other while fore/aft cyclic is applied to both disks so it has less cyclic authority in the left/right axis. Yaw is by differential collective combined with some cyclic trim to counteract the machine pitching in the direction of the rotor disk that has less pitch. Also there are elevator control surfaces on the boom that are used to counteract pitching in forward flight. You can read about this on pages 8-12 to 8-14 of the kmax flight manual.
The full scale Kaman is a study in elegance. No part unneeded and using the Wright brothers original concept of wing twist for control. Flying the servo flap instead of the rotor is mechanically effortless and immediately applicable - a way to dominate the rotor's inertia with nuanced airflow instead a mechanical arm twisting the entire blade assembly.
Ein super scale Modell... Das Flug Bild ist ein Traum 👌🏻 wie das original... Hut ab.
Fantastic and original twin intermeshing rotor rc model 👍
Perfekt !
Wow this is wild, love it. I fly Quadcopter and race quads FPV with goggles. Need a forward camera on this with some long range video transmitter !
Subscribed for more footage like this 👍
Amazing!!!!
Looks very fast
Wow❤️
I hope those 2 rotors are only driven by one gear like the real one
wow
I would love to see some details on how the model was built. Please post that!
mind to advice head speed and rotor shaft angle? thx in advance
How in the heck did he get yaw control? Are the control surfaces actually identical to the kmax with the flaplets on the rotor blades?
We build the real deal, but this is impressive!
This is how it is done on the real-life K-MAX, I assume it’s similar here (differential collective and cyclic): www.reddit.com/r/Helicopters/comments/4o5gvz/how_does_the_k1200_kmax_yaw_physical_rudder/
No way
What did that cost😮
Hello. I'm looking to find a fuselage or pieces to build one .... Do you have any information about it?... Thanks
Hello everyone. I've been reading the responses here and have a question. Some of you are using the term "servo flap." What is that referring to? I understand that the rotor blades have to flap to combat dissymmetry of lift in translational flight but I've never heard the term "servo flap" before. I did note that the direction of rotation had the advancing blade (the one that would be flapping upwards) of each rotor hub crossing over the adjacent rotor which should minimize the possibility of contact.
The original only maniuvers by using ruders like a plane.
This model apparently uses asymmetrical trust.
That's all I could gather.
Instead of directly adjusting the pitch of each blade, on the full size kmax each blade has a small airfoil (aka servo flap) positioned behind the trailing edge. The pitch of that servo flap is what's adjusted, and the lift generated by the servo flap puts a torque on the blade, setting the blade pitch. This greatly reduces the force required to set the blade pitch, allowing the kmax to not use hydraulics. It's the same concept as a trim tab.
How much for this?
