I've found KSP's spaceplanes exceedingly frustrating  the stock aerodynamic model flies all wrong to this real (albeit low hours) pilot. I just tried FAR  It does make the aircraft 'feel' much more aeroplane-like  and there is warning loss of lift before a stall and nice secondary roll when feeding in too much rudder. But it made everything keep way too much energy  it was almost like there was no drag at all. The stock Aeris was so floaty I could barely land it even power off  it was like trying to bring in a sailplane at the end of a good day, when virtually all the air around is rising slowly. So sadly I uninstalled after an hour or two. A neat thing to add would be the ability to define control surfaces as flaperons, so that they droop down and add lift and drag (to allow a slower and draggy-er approach) like flaps but still continue to operate as ailerons â€â€and allow us to leave off separate flaps or airbrakes. I'll give FAR another go after the next update.
