For better or worse, this is what I have been doing.

I picked the Impala, copied it to Impala 2, then set the inerita under Edit Aircraft to 50%, then went to the radio and flattened the Idle Up 1 curves near the center and have the max throttle position only give about 75% throttle and Pitch. When flying I normally hit the Idle Up switch so I am in Heading Hold mode (HH) With this setup, I was able to finally get tail in hover. I can now hover the regular impala without mods tail in and am working on side.
