Eagle Tree Guardian: How does 2D mode work in detail
Hi guys
I purchased a Eagle Tree Guardian 2D/3D. Installation was a piece of cake, setup was easy as well, everything worked fine but then, then i started to think... and this is where my problems began.
The Guardian is installed in a GreatPlanes Revolver70. Due to lack of free channels, everything but the "Gain" wire is connected to the receiver. I did not fly the model yet with Guardian installed.
In 3D mode everything works as it is expected to do and, most imported, as it is written in the manual.
However my expectations differ from the real world, when i switch to 2D mode.
According to my understanding, in 2D mode, the Guardian should level the airplane as soon as i release the sticks to center. The leveling function works as expected. But also should the Guardian treat stick defections in 2D mode as command angles for pitch and roll. This means if i give and hold, for example, full right aileron, the airplane should bank to a predetermined angle and hold this banked position as long as i keep the stick full defected. When i release the stick to center the airplane should roll back to level flight.
I can even adjust this maximum angles für pitch and roll in the 2D settings menu with the computer software.
When i now attempt to test this function on the ground something strange happens. The maximum roll and pitch angles are set to 60 degrees.
When i now give and hold full aileron, the aileron, of course, deflects. But now, when i roll the airplane, the aileron stays deflected until the airplane banked about 180 degrees and is already inverted. Then the aileron comes to zero deflection.
Is this the way it should be? In my opinion the aileron should go back to zero deflection when the preset maximum bank angle of 60 degrees is reached.
How can i test the 2D function on ground. Did i get anything wrong?
Additionally there seems to be no difference between "2D" mode and "2D + heading hold".
Could anybody please enlighten me
Thanks a lot

I can only confirm what you are saying: I have been using these untits for many years. What ET call "2D" mode, I call "landing" mode. I use it for landing, because in 2D mode, if you pull the elevator to flare, the ailerons remain in HH mode, so keeping your wings level. In 3D mode, as soon as you touch the elevator, the ailerons revert to AS3X (non HH) mode. But what you say about the bank angle in 2D mode I can confirm I had noticed that, and I never found a solution other than to live with it. Hope this helps you.
