Acceleration comparisons

Button trim usually is the more accurate of the two, since it is input in quite tiny increments (about 160 clicks from one extreme to the other), and on most aircraft it is more than adequate, in the sense that you can get to a 'zone' where one more click up or down makes no discernible difference. However, on some aircraft the transition from one click down or one click up always seems to be excessive at any throttle/pp setting; you will either be climbing or losing altitude, in a slight skid or slide or rolling to one side or the other unless you hold your stick absolutely rock steady precisely at angle X/Y. On these same aircraft, I also notice that you need to trim precisely for very small changes in speed and power, or the penalties in performance and speed loss can be severe.

Since I've only ever used trim on a hatswitch this may not be helpful, while being aware that trim characteristics of some planes have become less benign, experimenting with the response curves of trimmers assigned to axes (polynomial curves of the second or third power, maybe even exponential) could yield good results. There are also four control profiles available to save one's configurations for different planes. Well, awfully sorry if this wasn't helpful.

While it would prove hazardous to claim the acceleration in level flight to be exponentially dependent on Ps, one could say that it is directly proportional to gravitational acceleration and inversely proportional to the airspeed at the same time, at the alt and airspeed for which the Ps value is known. MaxGunz and FatCat have explained things wonderfully.

Just going from IL-2 Compare graphs, at sea level, that's exactly what the difference is: about 20% without WEP on and 15,something% with it... admittedly, I haven't done any tests myself.
