I’ve finally started work on David’s Bolt. First I have to say that this is one of the nicest finished CARF sport jets I’ve worked on. They have really stepped it up a notch. Working on the wings, the



manual calls out for 1” arms for both the aileron and the flap. 1” would work for the aileron but I found that 3/4” gave a better angle on the pushrod which results in a shorter exit slot. There’s still plenty of travel with the shorter arm. I went with 3/4” for the flaps as well and found even this to be a little long. 17mm is probably ideal. I stayed with 3/4” since this is what I have and removed a small amount of the inner skin for clearance. I also opened up a small hole in the aft wing root to get a straighter shot at the rear flap servo screws.
