Wrong behavior of Phantom

Postby Get » 21 Jun 2014 13:07

Hi all!

I have some troubles.
Now i am using:
- Licensed copy of Heli-X on Mac OS
- SM600 RC sim unit: http://www.goodluckbuy.com/6ch-rc-helic ... andle.html

1) When taking off, phantom starts rotating and i have no idea how i can fix it.
2) Notwithstanding that i have chosen FPV (view from camera) in parameters nothing happens, i still see only ground view.

Thank you in advance for support.

"starts rotating" sounds like your "tail" channel is not calibrated properly. Please check and recalibrate when necessary.

FPV only works in artificial 3D-scenarios - the photographic sceneries are tied to a static point of view.

Have fun ;)

Actually, I have found out that the Phantom is not too realistic when you let go the joystick handle after moving in one direction. In reality, it returns to a horizontal position and holds this. In Heli-X it is unstable like a heli and just flies away. Can I tweak some settings to change that to make it more stable?

It does not simulate GPS supported ATTI mode to hold position (for which sim training isn't really needed anyway :) ). Only self-leveling function like normal ATTI (IdleUp1) and Manual mode (IdleUp2).
Also in reality while in normal ATTI the quad would continue to drift. In Manual mode comparable to a heli it would also not return to horizontal position but keep it's current orientation when releasing the sticks.
Modelling helis for Heli-X! See model build log here.

Are you sure it's the GPS? I would say it's the acceleration sensor which leads to a compensation movement to roughly get rid of the drift after a handle was released. This could easily implemented into Heli-X. The GPS is too slow and inaccurate for this quick job but is used afterwards to help holding position.
