Hello

Can 6.5kg-cm MG servos be used safely on a pitts s12 with a 50 cc gas engine ? the planes total weght will be around 7.5kg i think . And it will have 4 ailerons with one servo on each , and 2 servos on the elevator.

This is the plane : http://www.sdshobby.com/pitts-s12-50...me-p-1206.html

This would translate to 232 ounce torque? lets say 180 realistically/normally/ideally?
Should be just fine unless you are abusing it and doing full throttle blenders and various other high speed abrupt changes in heading.
use a good battery, such as an A123 minimum 2300, or lipo or dua,l to keep up with draw from several servos.

6.5 kg-cm is about 90 oz-in of torque. But logically thinking it should be more than enough for 7 kg plane ?

They should be fine as long as they are full "standard" size servos. Some of the "min" servos gears are a little delicate for a gas plane.

Yes , they are standard size. Thank you for advising
