A Technology Demonstrator

No details, just build under 100 parts, but it was quite a challenge to build the INTERMESHING ROTORS since it crushes into each other. After crushing so many times, and changes, now it is safe to fly, and you will see how stable it is.

Instructions:

Takeoff: throttle 100%, then, push the VTOL slowly and take off.
Landing: Lower the VTOL halfway or more, to reduce the altitude. Take care with the downward speed (watch the rate on the altimeter). If it is too fast, pushes the VTOL up a little again while nose up. Nose up (pitch) will also lower your forward speed so that you can hover and land almost vertically.

Reduce the throttle (engine) once you reach the ground.

How to fly the intermeshing rotor helicopter in SimplePlane

a few notes to add..

This build is important for me, not much in detail or aircraft livery, but it is challenging in terms of physics - the rotors and I have spent hours perfecting the balance and placement

Intermeshing rotors/synchropter

(Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions, with each rotor mast mounted with a slight angle to the other, in a transversely symmetrical manner, so that the blades intermesh without colliding. The arrangement allows the helicopter to function without a tail rotor, which saves power. However, neither rotor lifts directly vertically, which reduces efficiency per rotor.

This configuration is sometimes referred to as a synchropter.

Very few helicopters with this configuration has been produced. well, no wonder I have crushed for at least 50 times, spending about 6 hours for this crazy rotors.
