A technic helicopter that I designed for competition “take the challenge” on the official lego website. Features rotating and swiveling main rotor, and rotating tail rotor. Including building instructions.
The construction was really classic. The frame supports all the components. The handle on the left is used to rotate the rotors. The mechanism of swiveling is composed of two main parts. The first is the part used for swivel on the right/left directions. It’s composed of a axle which pushes or pulls a 9L connecting rod connected to the main rotor. The second part is used to swivel on the forward/backward directions. It’s composed of a connecting rod 6L which pushes or pulls the slide system, and with a 45°-oriented liftarm transforms the movement to the main rotor.
I have made pro building instructions using MLcad and Lpub. As usual, you can buy it for 5€ and then download the instruction immediately. Here is the complete bill of material in picture file :
But you can also checked it on rebrickable (or make any export you want)

i like helicopter. i am trying to built a helicopter.
thank for ideas.
the the main rotor forward backward are reversed is because of size limitations in the model. im thinking of making a larger version of this heli with acurit main rotor movement. nice model once its built and running
I had to order a few parts but have now built your helicopter. Really a great model. Thanks for shareing.
Two points though:
1) Pic 3 of the instructions name an axle length 7. I had to swap it for 6 and remove the bush. Otherwise things didn’t fit.
2) When you tilt the pilots stearing rod, the rotor must tilt in the SAME direction so that the air is pushed to the other side. This is set up correctly for left and right, but the wrong way around for forward and backward.
Stil a really great MOC, thanks again!
It’s amazing work! You are the godfather of LEGO!
I finally make this heli and using a minimotor (lego red mini motor)and looks fine (the battery are a 9v adapted (with a tape) 😉
ups I forget to put in the earlier message
you can put the parts list ?
thanks and regards
very nice helicopter, I tried to make for my child
but need more pieces 🙁
I can use the power functions in this ?
(two m motors, battery pack, ir receiver)
