This helicopter has Speedometer (6 axis accelerometer) hooked up to the cyclic. Only two angular outputs of the speedometer are being relayed back in to the cyclic. This is shown in the start of the video where the swashplate delays in moving in to the same orientation as the body of the helicopter. The speedometer is applying cyclic to try and dampen the movement. The same as a flybar. Where via precession, The pitch on the blade are moved to dampen any change in orientation. Here I'm doing it electronically. The flybar lookalike on the hub is a precession bar. The idea on this unlike a Flybar is to increase the overall mass of the rotor disk. Therefor increasing it's tendency to resist motion, the paddles on the end of it are to create some air resistance. They basically act as a big air brake. It slightly improves stability and noticeably decreases vibration. Also the Rotor head semi rigid now, Therefor the blades can pivot relative to the main rotor shaft But are dampened so they will level out if moved.

  • :'( That song is so sad.

    how long have you been using wiremod to figure all that out? Or did you use a tutorial?

  • The actual wire is quite simple, and no tutorial was I use, I've had to learn all this by trial and error with a bud of mine. He helped a WHOLE lot on getting these heli's to fly.

  • Wow, that is amazingly stable. You are really coming a long way, great job.

    btw, what is with the music? lol

  • Space Lion from the Cowboy Bebop OST. Great music. <3

see all

  • In other news, that's freakin' amazing! Only other helicopter I've seen that uses collective pitch and a swashplate to move was incredibly unstable.

  • @XXXmags I was going to say, the mechanics of getting the helicopter to go up, down, be stationary, move forwards, bac... lets just say in all directions, aswell as turn, is a lot more complicated than the wire involved.

    I've never fully understood swashplates, but that's what makes me love them.

  • Now that you seem to havethis all but down pat, I have a challenge for you.

    Take a look at the Chinook. Think you can pull that off to the point where you could load two buggy's on it?

  • ARGGG, I ALWAYS see that brick texture that you see from 0:00 - 0:20. Where is it, I have been wanting to find it for a long time.

  • This is by far the most stable and smooth-flying helicopter i've ever seen (In Gmod, that is)..

    Way to go!

  • this is awesome. i'd say i DEMAND a tutorial, but that might just be a little to overruling xD
