Haven't had any problem with any of the control horns that I have, but having a little extra on hand just in case is the best way to go. Thanks Flite Test

So simple. Glue n go. Been flying for over a quarter century and these servo horns are so simple to use. Just make a small slot, a dab of hot glue and then by the time you've put in a battery and walk outside its ready to go.
Love the product. Thanks guys.

sure saves a lot of time and effort for a buck a plane thanx again
