I use JR *SA's in my pattern planes and Hitec 7955TG's in my IMAC plane. The JR digitals have been super reliable and very smooth and accurate. The Hitecs are a bit "steppy" when compared, and the aaccuracy is not quite there.

Have a friend flying F3A who did use Hitec in one Pattern plane. They worked OK, but he didn't use them in subsequent planes . . although, I would never beat this guy no matter what servos he used !

Never had an issue with JR servos in Pattern . . Had a Hitec "burn out" in a IMAC plane (not many flights on it either). I have now seen 3 Hitecs "melt" in IMAC planes in various configurations (being used by top pilots too) . . never seen this with JR or Futaba in IMAC.

Have replaced Hitec with JR DS6301 now, so see how that goes
