Inner flaps (cont)
pic 1:
Parts used for the inner flaps.
Dubro #557 white plastic horn brakets screwed onto the flap torque rods.
The servo side gets two 4-40 ball/socket sets.
One socket on the bottom of the servo arm and the other socket on the top.
Last are two 4-40 clevises to connect to each plastic horn bracket.
I wanted to use ball/socket instead of the clevises but no room to connect the socket to the bracket via a hex head bolt.

The inside edge of each flap recess on the inner wing gets an enlarged hole to get the torque rod with attached horn bracket into the center wing.

As with the Yellow Texan, I'm using Robart's pocket hinges so the flaps can be removed for painting and future work.
(also still need to glass them).
pic 4:
There's not much clearance between the top of the servo and the servo arm so I put the hex head bolt in from the bottom side.
pic 5:
Set up complete.
All dry fitted.
As mentioned previously, I cut an access hatch in the bottom of the center wing so I can easily get to the flap set up.
I'll probably have to re-inforce those flap torque arms with some balsa and fixed gear straps.

My Bob Dively P-40 cockpit kit just came in.
That should be about it for all the major items when I start on the Yellow P-40.
Always nice to get all major parts before building in case something is no longer made or back ordered.
