Everyone should set everything that has the word Expo in it to 0. I know by default it is set to .10, but Boris himself has said it''s unnecessary, and you should remove it. ONE caveat: if you disable superexpo_rates to get the old linear control back, then you may still want to use some expo parameters to change the curve. Other than that

TECS (Total Energy Control System) For electric aircraft, make sure this number is achievable at the end of flight when the battery voltage has reduced. AIRSPEED_MIN: This is the minimum indicated airspeed (in metres/second) that the speed controller will attempt to control to.

A pilot uses flight control systems to control the forces of flight and the aircraft's direction and attitude. It should be noted that flight control systems and characteristics can vary greatly depending on the type of aircraft flown. The most basic flight control system designs are mechanical and date back to early aircraft.
Flight control systems are subdivided into what are referred to as primary and secondary flight controls. For steady flight, aircraft must be in a state of balance (zero moments around the axes) and the controls enable this to be achieved for all possible configurations and CG (Centre of Gravity) positions.
A battery is a device containing one or more cells that convert chemical energy directly into electrical energy. With the exception of the most rudimentary of aircraft types, virtually all aeroplanes incorporate an electrical system. In the vast majority of cases, the primary electrical system incorporates one or more batteries.
Secondary flight controls are intended to improve the aircraft performance characteristics or to relieve excessive control loading. These consist of: The movement of the flying control surfaces in response to the movement of the cockpit controls may be achieved: Mechanically.
( b) Each element of each flight control system must be designed, or distinctively and permanently marked, to minimize the probability of incorrect assembly that could result in the malfunctioning of the system.
( a) It must be shown by operation tests that when portions of the control system subject to pilot effort loads are loaded to 80 percent of the limit load specified for the system and the powered portions of the control system are loaded to the maximum load expected in normal operation, the system is free from— ( 3) Excessive deflection.
