Indeed the numbers are way overkill for that particular airplane and will buy you nothing However I suspect if those numbers are even remotely real. I goggled tower pro sg5010 expecting to be taken to the tower web site but instead to some unknown peddler and an eleven buck price tag. There are so many counterfit servos flooding the market these days its amazing as well as a crap shoot.
That sixty sized trainer needs only standard servos and anything more is a waste of money. A nice compliment using Hitec (my preference) would be Hs 435 elevator, Hs 225 rudder, two Hs 225's aileron and Hs 225 throttle.
