Hi guys,

 

This flight went well IMO. Still trying to be smooth and fly where I want to but I'll be honest I didnt plan on ending up where I did :megalol:

 

Please check it out if you have 10 minutes spare.

 

All comments appreciated.

 

Is there a way for auto pilot to maintain a height I set? so I can turn and it keeps 50m for example?

 

Thanks :D

Hi,

 

Is there a way for auto pilot to maintain a height I set? so I can turn and it keeps 50m for example?

 

there is the ALT HOLD (LShift-A), which is the fourth button of the four green autopilot channels on the right. PITCH, BANK and HEADING HOLD are the others that can be turned on/off there. Note, that the height is measured by radar (<=300m) or barometric (>300m). You have to tell the autopilot which one to use (LCtrl-X).

 

It should keep your height within it's limits (i.e. smooth turns etc.), you set height when releasing the collective break ('F' - key). Nevertheless, your control input is priorised, sharp manoeuvres won't be fully compensated.

Unicorn0578, I made a quick trk for you to observe.

But a couple of tips first.

1- Try to keep your inputs to the cyclic and collective smooth, in general helo's are slow to respond to inputs so keep it smooth is very important.

2- Trim when you are trying to maintain the helo's attitude in level flight, try not to trim when banking.

 

In my trk.. I used a couple of different ways to maintain a constant altitude bank.

Firstly when I take off, trim for level flight (check Verticle Air Speed Ind) and turn on Alt Hold, I turn off Heading Hold and use cyclic and rudder for a smooth turn while maintaining altitude. Its important to be smooth on inputs especially cause the Alt Hold AP only has a 20% authority on the collective inputs.

In the next banking turn I leave the Heading Hold ON but while maintaining my turn I hold the trim button down.

Help this helps in some way.
