clandestoy, that is alot of servo. back in the thread i posted my calc for servo strength needed. with both E 56oz-in are required, i've installed a 75in-oz servo for both E halves.


Did the calculation on servo size required:

Aileron:
2.75x13.5 / 120mph / 15degree surface defl / 30 degree servo defl = 24.598 oz-in
2.75x13.5 / 130mph / 15degree surface defl / 30 degree servo defl = 28.868
2.75x13.5 / 140mph / 15degree surface defl / 30 degree servo defl = 33.48

Elevator:
2.75x11.25 / 120mph / 15degree surface defl / 30 degree servo defl = 20.498 oz-in
2.75x11.25 / 130mph / 15degree surface defl / 30 degree servo defl = 24.057
2.75x11.25 / 140mph / 15degree surface defl / 30 degree servo defl = 27.900

Rudder:
4.5x9.125 / 120mph / 30degree surface defl / 30 degree servo defl = 148.853 oz-in
4.5x9.125 / 110mph / 30degree surface defl / 30 degree servo defl = 125.078 oz-in
4.5x9.125 / 100mph / 30degree surface defl / 30 degree servo defl = 103.37 oz-in
4.5x9.125 / 90mph / 30degree surface defl / 30 degree servo defl = 83.73 oz-in
4.5x9.125 / 80mph / 30degree surface defl / 30 degree servo defl = 66.157 oz-in
4.5x9.125 / 70mph / 30degree surface defl / 30 degree servo defl = 50.651 oz-in
4.5x9.125 / 60mph / 30degree surface defl / 30 degree servo defl = 37.213 oz-in

Inner Flap:
3.625x7.125 / 100mph / 45degree surface defl / 60 degree servo defl = 55.103 oz-in
3.625x7.125 / 90mph / 45degree surface defl / 60 degree servo defl = 44.633 oz-in
3.625x7.125 / 80mph / 45degree surface defl / 60 degree servo defl = 35.266 oz-in
3.625x7.125 / 70mph / 45degree surface defl / 60 degree servo defl = 27 oz-in

Outer Flap:
3.375x7.375 / 100mph / 45degree surface defl / 60 degree servo defl = 49.44 oz-in
3.375x7.375 / 90mph / 45degree surface defl / 60 degree servo defl = 40.047 oz-in
3.375x7.375 / 80mph / 45degree surface defl / 60 degree servo defl = 31.642 oz-in
3.375x7.375 / 70mph / 45degree surface defl / 60 degree servo defl = 24.226 oz-in
