The QC2 is an excellent choice. Very small, no motor limit.

The KO VFS programmables are great too. Like the LRP the servo footprints are very small.

I'm not big on the GTX as the footprint is bigger. In 19-turn and stock I've gone to the KO (in fact I still have a QC2 to sell in EXCELLENT condition). In mod I use a GTB (wish the footprint were somaller)/Velociti set-up.
