I just read a report posted in the pattern forum. A pilot flew a 2 meter pattern plane through the FAI sequence and recorded the draw between each individual servo and the receiver. The highest recorded draw by the rudder during a knife-edge loop, translated to only 21oz-in of torque! There are not many replies to the thread, so I wanted to hear some other input on this test/information. Is there really no need for more than 90oz-in servos in my planes?

Here is the [link=http://www.rcuniverse.com/forum/m_8189267/tm.htm]thread[/link] and here is the [link=http://www.ofremmi.info/F3A/Technic/Flight_testing/servo_flight.htm]report[/link]

I was just about to get some 130 oz-in servos for my 120 Yak rudder and elevator, but now I might just get some more $30 DS821's?!
