    unless you apply more throttle early then it's going to hit the ground
    It's all about knowing when to add pitch (and enough of it) to stop that...
    Have fun!

      Also, do you mean coming down at a nice 45* glide path or coming straight down?

      If you mean coming straight down you are always going to come down quicker as you are travelling down in your own rotor wash so effectively you are trying to fly in downward travelling air. It's called a Vortex Ring and it's not good

        He said "if you could keep a marble in the centre of the glass you had a good chance of being able to hover a real one.

        Sounds more difficult than a computer sim to me but i bet it did help with cyclic dexterity.

        I made something along those lines years ago before I even had a heli,it was in RCME I think.

        It was okay,but soon got boring.The family soon get fed up of the drum roll when the steel ball bearing bounces on the table you've got it set up on.

            So how do you overcome that?

              The response to collective pitch is complex.
              When the heli is not horizontal a little more collective is needed to keep the same altitude. So even in flat calm air you need some adjustment to collective to maintain height unless you keep the cyclic absolutely still!
              Near the ground it takes less power to hover, but the heli sits on a cushion of air and skids about sideways.
              That effect gets less until it is a lot easier to keep it still at 4-5 feet up.

              Next thing is when the heli is moving then there is translational lift on the rotor disc so when it is going fast it needs almost no collective to stay level.
              Of course this translational lift also occurs when the wind blows past a stationary heli.
              On top of the translational lift is the reduced vortex ring - in fact they are having the same effect.

              If you are in a turbulent area such as behind tress or something on a windy day the air itself will have movements up and down that you must coompensate for.

              Before flying the real model you should try flying with some different wind and turbulence conditions on the sim, and also some different wind directions too as you might want to fly with the real wind in a different orientation to avoid low sun when you start flying for real.

              I'd like to have an option to select random weather conditions in phoenix rather than having to think about it and set it.

                You don't basically, it's a fact of life.

                You just need to be very gentle with your stick inputs and come down slowly.

                  I've seen video of 3D moves where the heli comes down fast and at the last minute shoots back up again. Very fast response. I can't get anything like this behaviour in the sim even when playing around with the 3D models. Does it sound like I need to make adjustments to the pitch curve in my tx?

                    Certainly the Synergy N9 and Raptor 50 3D and a numbers of others in the sim will be capable of rapid pitch responce, it might be your transmitter settings if you have reduced pitch ranges in this or the pitch channels ATV/travel adjust then this will effect pitch responce.
                    The other thing which might come as a suprise to you after learning to use small measured inputs to hover is just how quick and agressive you have to be on the pitch.
