thanks for any info

To answer this, does this airplane have flaps, or is it full span aileron?

IT has full A rons no flaps

With torque rods... you could have the aileron servos in the center of the wing, side by side. This would eliminate the drag of external control linkages. (which is minor...)

Typically, the servos would be appx 1/3 to 1/2 of the control surface's area out from the root. That would be in the 2nd 3rd bay out from where the wing meets the fuselage. You really can't place the servos badly if you try to almost center them on the control surface.

Time for an orientation check... My impression is that Dynaflite used to make a .30 size Mustang (a while ago) and a .60 size mustang (fairly recently). Now a 51" warbird for .60 sounds unlikely to me, so I gotta ask... are you putting a ball bearing, schnuerle ported .46 on a vintage .30 size plane?

If so, I'd expect you'll want at least as much torque as a standard servo (although the CS-12 does deliver about 80%). I'd go with something bigger, if it'll fit. If a more powerful servo won't fit, I'd get a bigger airplane -- seriously.

Al , this is a .30 to .45 rated plane . the dyna fun fly
mustang #3011. I plan to run a .46 tower in it or a gp .42 TT.
very tricky to build , doesnt have any tab and notch , like PICA
ETC . on the fuse. wing is going well though. JUST DONT LIKE
THE single serv a ron setup. in fact i should have installed two servs in my trainer wing.

Ah, I see.

I guess the thickness of the wing would have to effect how you put the servos in, huh? I think if it were me, I'd try and put them right outside of 1/3 the way out the wing if they'll fit there...

FHH does tend to be on the money... and he hit both of what I'd call your best options: if it won't fit in the wing, into the fuse with torque rods is probably the way to go. I wouldn't want to mess with bell cranks (each presents three extra places to introduce slop), and I guess I prefer torque rods to flexible pushrods. Just don't want to allow much extraneous movement or flexibility in the ailerons of a plane with a pretty hefty power loading.
