X-ACC

From UfoWiki

This is an additional module which can be plugged into the X-Base like the X-3D.

Using the mounted 3-axis acceleration sensor the UFO can easyer find the horizontal position. That way it will be steered through angles off the horizontal position. This means the UFO will automatically get back into the horizontal position if you release the control stick. The X-ACC has to be calibrated using the X-Control Software before flight, due to fabrication tolerances. It's not possible to plug in the X-ACC 100% right, so the UFO will drift a bit, which can easily be fixed using the triming funktion of the remote.
