RE: Zlin 526
Father's day and I got some work done on the Zlin. I went to the Scale Masters qualifier here yesterday and was inspired to get this thing farther down the road and do the best I can, which means constantly telling myself to "slow down and think it through".
So, here is the right wing panel on which I have had to really think from time to time. As you look at the trailing edge you can see a 1" chunk of balsa running the length of the trailing edge. It is a jig. This plane has an amazing 6 deg of washout, as you can see if you look closely at the end rib, so the trailing edge is built 1' off the board. Then to make things more intersting, the wing has a 4 deg angle of incidence at the fuse. So I spent quite a bit of time checking and re checking everything just to be sure before I glued things in place.
The servo is located so that the control hookup remains scale which means it is buried in the wing and there "ain't much room" in there. I am really uncomfortable with not being able to get at a servo short of ripping into the wing so I cobbled this installation together which I am sure will do the trick. Esentially the servo is mounted to an aluminum plate which slips into a slot and is then is held in placw with two 4/40 screws. The servo will be accesssable through a door in the underpart of the wing which I will make as hard to see as possible. If anyone has a better way of doing this job, I would love to hear about it.
I'll get the second panel going and then start on skinning and joining them to the center section.
Later,
