the more forward you have the CG the harder it is to slow down, it takes much more stab travel (and you'll run out of stab) and more turbine power to get the AOA up so it'll slow down on landing. I've had just about every F-16 out there and what worked best for me was to get 'in the ball park' with the CG based on the recommendations then adjust it so it's hands off when inverted or up right, then they hold a high AOA easily, slow up nicely, don't use as much stab on landing and aren't pitchy. either way for landing you need all the stab travel you can get. on the skymaster i think i ended up around 150-155mm
