After some investigations, the only way I've found for improving the cockpit of this plane is to install a better 2D panel from a FS2000 Carenado Tomahawk (the model of this plane dont work in FSX), that is here:
http://simviation.com/1/search?submit=1&keywords=tomahaw2.zip&x=17&y=11You have the plane in "your FSX"\SimObjects\Airplanes\Piper Tomahawk, so proceed as follows (don't hesitate to ask in case of doubt):
1- Download the plane (Piper Tomahawk CC-PAL) and extract it.
2- Copy (extract all the gauges into the
panel folder of Piper Tomahawk CC-PAL.
3- In your FSX\SimObjects\Airplanes\Piper Tomahawk, make a backup of the original panel (rename it).
4- Copy the panel made in step 2- to Piper Tomahawk.
At this stage you have a 2D panel only, but with multiple views and also a VC but with no gauges and the infamous square, in this case in black.
In order to have a better view os the VC when cycling views, you can restore the original (the square problem will be the same as in the original):
5- Copy the gauge PA38.gau from the original panel to the new panel.
6- Add the following text to panel.cfg after :
// Panel Configuration file
// Chincul PA-A-38 Tomahawk
