These models are expensive and a great deal of work goes into building them, so why not have as much information available to you as possible.
Here is what I would like to have annunciated to me while I am flying either when I command the plane to perform a certain maneuver such as a landing or on demand like when I am about to enter an aerobatic maneuver like a roll or loop etc. and would like to have my air speed above a certain level.
The system can give me this. What I am personally looking for is the following while the plane is in the air.
-airspeed every few seconds when my gear is down and my flaps are down for landing.
-confirmation that I have put my switch into the gear down position or up position.
-confirmation that I have put my flaps into either the take off position or landing position
-amount of fuel remaining in the system either in % or ml.
-exhaust gas temperature
-stall warning
-over speed warning
