Bob Brown Posted January 14 Share Posted January 14 Don’t glue 9g servos into the wings. Instead of gluing 9g servos into wings due to the limited depth of the recess, try using one of these servo mount designs which give free access to the servo. There are two types, one in which the frame is fixed down into the recess and the other which incorporates a servo cover and is fixed to the wing surface. These are 3d printed designs which are freely available on Thingiverse and only cost a few pence to make. Here are the Thingiverse links for the files and full details. https://www.thingiverse.com/thing:6859356 https://www.thingiverse.com/thing:6721166 2 Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted January 14 Share Posted January 14 Interesting, I normally use heat shrink tubing, and glue them in, cut the heat shrink to get the servo out, or glue them to the wing hatch. 1 Quote Link to comment Share on other sites More sharing options...

Geoff S Posted January 14 Share Posted January 14 When I have glued servos in, I wrap them in paper masking tape first which is less substantial than heat shrink and easier to remove. 4 Quote Link to comment Share on other sites More sharing options...
EvilC57 Posted January 14 Share Posted January 14 I fix them in with a couple of beads of hot melt glue on foamies. Then with my small heat gun set to 100°C, I can easily remove them without damaging either the foam or servo. 1 Quote Link to comment Share on other sites More sharing options...

Simon Chaddock Posted January 14 Share Posted January 14 (edited) I glue everything in but the battery! I find a well thought out and efficient servo linkage means the servos last a long time, usually longer than between major crash rebuilds. An example. The aileron servos on my sub 250g Depron Super Cub built in 2013 have never been changed and they are driven by super cheap 3.7g servos! It is still flown on clam days. The servos are buried in the wing with only the tip of the servo horn showing. Mechanical aileron differential is included with the servo horn angled forward about 40 degrees. Light and simple no adjustment is required as the link rods are made from a paper clip and are bent to be an exact fit. If it is not quite right then make another. It is only the cost of a paper clip! 😉 Even more important there is a very free moving and virtually invisible top tape hinge. In this installation the servos are never worked hard. Just saying.
