Well, now that the Aircraft Converter is working on my computer, I was eventually able to compile a DR400 with a home made real DR400 airspeed indicator in kt instead of the default one in kph.
Some DR400 in France keep using this ASI in kph, but all the HB Robins I've been flying have such an ASI in kt, thus now i feel home in this DR400.
Unfortunately, I was unable to identify how to change the needle. Does anybody know in which texture it's hiding ?
Thanks in advance
