Control horns

[Ernie]

Hi mes amis,
  I am having trouble trying to attach the little control horns on the stabilizer and
rudder so that a slight wind won't knock them off.  I eventually want to attach
the control wires to them, but as it is right now, they just aren't secure enough.
  What would you suggest to anchor them so they are useable?  (it's 1/32 scale).

Thanks for your help,
Ernie

 There is very little surface area on the bottom of a thin control horn to produce a strong bond no matter what type of adhesive that you use. Tom Morgan makes his control horns with the upper and lower horns as one fabricated piece. He sandwiches the preformed control tempered hard wire (two ninety degree bends) between two outer layers of thin sheet styrene cemented together. The narrow slot in the control surface is produced with a fine tooth razor saw.

I have attached many many many control horns and have never had one come adrift, yet. Most control horns are supplied as one piece items and fit into a slot or a hole in the aileron, rudder or elevator. These are usually a pretty good fit in the slot and once positioned I apply a drop of CA (super Glue) to the base of both sides of the horn where it fits into the control surface, it is importand to use the very runny CA as it flows into the slot and around the control horn.

If the control horn is a two piece item, one for each side of the control surface, I apply a small amount of plastic glue to the bottom od the horn then place it onto the control surface, once dry I then apply a small drop of CA around the base of the horn.

Sometimes I make my own one piece control horns, I use sheet brass, these make excellent control horns and are very strong, CA sticks to them very well.
