Refueling tips for Saitek X52 Pro users
I recently purchased an X52 Pro, primarily to get the throttle stick for aerial refueling. While the stick has been an excellent addition to my flight sim experience, I found that my aerial refueling was still suffering - short boom hookups and many disconnects. However, I adjusted my axis curves and the results were IMMEDIATE - I was able to completely refuel the A-10 on the first try after making the adjustments.
I have posted screen shots of my axis curves, but of course everybody's preferences will be different. However, the biggest positive change for me was the throttle curve. By setting it to -15, I found that I could finally control my distance on the boom. This curvature makes it so that movements on the throttle have less of an increment or decrement effect at mid levels. Sure, I still disconnect a few times, but it is extremely easy to get back onto the boom and continue filling up.
So, if you are having trouble with your A-10 refueling, particularly many boom connects and disconnects, and you have an X52 Pro, at the very least change your throttle curvature to something in the negative range. You might be surprised at how effective this small change is.
Good luck!
