I am flying the A2A C172R right now and I have a hard time setting the exact heading using the HDG bug and the right OBS on the VOR gauges because the plane uses the default FSX mouse wheel acceleration (when you start scrolling, you start with small steps but within no time you are taking huge steps which makes it VERY hard to precisely set the HDG and OBS).

 

I've read that FSUIPC has an option to disable this annoying behaviour but I wondered if there is another way to get this done by hacking some file...? I fly with DX10 and so I don't have tooltips and setting the exact radial and heading is hard to do and very annoying...

I cannot find anything about scroll wheel acceleration in the FSUIPC documents.  Perhaps you can adjust this through your Windows mouse control panel.  A friend of mine found a set of Lua scripts for FSUIPC that allows you to enter the frequency directly into Navs and Coms using the number pad on your keyboard.

 

This is the original set of scripts he found:

He has been working (successfully) on expanding this to add several (IMHO) very valuable features.  We are testing these now and I am re-writing the original readme file so that all of the instructions are included.  Nonetheless the original version works well and so if your setup includes a keyboard with a number pad you are welcome to try it.  If it works (it does in the default FSX aircraft but has not been tested in add-ons) e-mail me directly at [email protected] and I will send the updated versions as soon as they are out of 'beta testing'.

 

As an FYI - the updated version -

• Allows you to see the numbers sequentially as you enter them, on the radio display that have selected (the original version does not change the frequency until you have entered all of the numbers)
• Has the capability to enter the autopilot altitude, vertical speed (+ or -) and heading
• Has the capability to enter the OBS1 and OBS2 cursor / card direction (also sets the HSI needle for aircraft with an HSI vs. standard VOR head)

Acceleration is controlled by the guages so you would be better off asking A2A to remove or put in a feature that can disable it or you could have fun and try to edit the A2A guages

Affirmative, Paul is right.

 

The acceleration happens when key coammands for the Heading Bug are used too ........ so FSUPIC or other methods won't stop it - it needs to be ironed out within the gauge I believe.
