HH139 Project (Inexperienced heli maker)

2,222 MTFUE11  one month ago

As previously mentioned on my Su-25K remake2 (done) post I said I would have made the Italian helicopter HH139. Problem is... I want to had some details... And when I work on it... Is while being on a shaky bus or a shaky train. I also know very little about helicopters with a main rotor and a tail rotor so it will take extra time. Does anyone know anything about helicopters? If yes, here are some info's...

Weight: ~3'600kg

Small main rotor: 1528hp, 441inches length, 1.0x thickness, 5 blades, swept style.

Tail rotor: 154hp, 89inches length, 2.2x thickness, 4 blades, tapered style.

    @MTFUE11 I know the basics
    What I can tell for your heli:
    You don't need a gyroscope if you tune the heli parts well.
    Tail rotor:
    - Mode: head hold
    - Linkage speed: 0.00s
    - Gyro speed: As you like, it's the speed you need to complete a full rotation.
    Main rotor:
    - Power: You don't need so much power, reducing it will set a more realistic spool time, and and make a realistic effect of lose of power if you pull big inputs on the rotor.
    - Cyclic pitch / roll : adjust that to be easy to control and to don't have too much input. Somehow Heli rotor output is exponential and I don't understand that. I don't think it's the same irl.
    Apart from that, it's not bad. Your "blocky" building style is special but well made !

    @SilverStar, do you know anything about building an heli that's stable? That's my main problem

    For details, you can add antennas, walk step, pitot probe, some air inlets, grills, door pivots...
    If you need a tester, you can call me.
