View Full Version : mounting servos in the middle of the wing
Hi guys, I am trying to mount the 2 seperate servos that will work my ailerons, this is not the first time I have done this, but I am looking for a better method. Up untill now, I have just glued in 2 hardwood braces, then screwed the servo to these rails, but the servo sticks right out, and it doesnt look too appealing, I have seen in pictures, where the servo is almost totally concealed, lying on its side, and all you really see is the servo arm sticking out to move the rod. Has anybody tried this method, or do you know of a better method to mount your servos in the wings? I would really like to hear from you if you get a chance. thanks in advance guys, all your help is trully appreciated,.....Joey.......

I use both methods. For aerobatic planes I use your method. If a scale model or for better looks I mount the servo on 1/16 in plywood hatch cover laid on its side screwed to two 1/4 in. ply or spruce short rails, the width of the servo with a slot cut in the hatch cover for the servo arm to move in. Four 1/4 square spruce corner pieces to screw the hatch cover to in the wing. Wish I knew how to post a picture, would make things easier.

here is a pic of what flypaper is describing. I hope this might visually help.
Thank you flypaper and flysrc, that is exactly what I was looking for, between the description and the picture, I can try it in my plane now, I have one question though, if I understand this, it means the entire servo, and brace are connected to the hatch, if by chance the hatch should come loose, I will probably be out of luck? I will just have to make sure the hatch is made to never come loose. thank you guys for your help with this, take care....Joey.........

If done correctly, the hatch will be quite secure. The jet guys have been doing it that way for some time now, and they can pull some pretty good G's. (I should know, I are one. :P )
Just make sure that you use something fairly hard to screw into at each corner of the hatch, and that it is firmly attached to the wing structure.
One one of my jets, I used 3/16" plywood triangles in each corner with very small countersunk phillips head screws (I had to use a jewelers screwdriver.) The plywood triangles were supported by balsa triangle stock. After drilling and instaling the screws, I took them out and put a couple of drops of CA in each screw hole to harden them up.
If you need some pics, let me know.
Thanks Jim, I like your idea of using triangle balsa to brace the hardwood, under the hatch, I will give that a try, thanks,,,,joey......
