SUCCESS!
The Sabre XLT successfully flew 5 flights this weekend and taxied back each time! I found the speed brake to be very effective in allowing a steeper approach angle without extra speed and allowed a shorter approach. The Sabre will turn on a dime and is very stable at high AOA. It is very easy to fly and is lots of fun.
The first flight this weekend is posted here:
