hey all im looking at ordering some servos out of china to put in a house of balsa 1 1/2 a mustang but thought i would ask your opinion i am looking at ordering some hextronic 9gram micro servos rated at 1.6 kg of torque..will these servos be good for a plane this size and for that matter would this size servo be okay to use in any .25 size plane application?

i am also looking at ordering some hextronix 55 gram servos rated at 10kg of torque.these are standard size metal geared servos and i am wondering if these would be good to put into a hangar 9 sundowner 50 and perhaps my top flight 60 size p-47 thunderbolt.. these servos are very cheap top buy but i am reading nothing but good things about them. im only have kg torque ratings and not ounce ratings since its a metric website...any help with these servos would be great or if anyone is using them can give me some info on the micros and standard servos and what pplications i am okay to use them in would be very helpful!
