I was just looking through my photos from this summer at the NCFFA nationals and looking at one photo reminded me of something I though I should share with the guys in here.
I know for my self when I need the extra travel on an control surface I look to for the Dubro long servo arms in my servo-arm box. between that and the computer radios usually I can get the travel I'm looking for.
this summer I had a chance to look at some other builders and see different tricks. one guy had and interesting idea. he was making his own servo arms out of light ply. he would mount it to a round servo arm with two screws and presto you know have a servo arm as long as you want. Take a look at the attached photo to see what I'm talking about. look closely at the elevator servo on the boom.
this is as clear as I can get the photo
