RE: Yellow P-38 build thread
Counter weights:
pic 1:
I cut the counter weights in half and epoxied in some 4/40 steel rod.
pic 2:
Holes drilled into the elevator and the counter weights dry fitted in the holes.
Will epoxy after all the wet sanding is done.
----------
elevator (cont)
pic 3:
Four large Robart pin hinges epoxied in the elevator.
Note: I made a 1/4" ply (with hole) that will support the outer ends of the control horn rod.
pic 4/5:
Elevator epoxied into the horizontal stab and the control horn rod supports also epoxied in.
The bottoms of the booms were trimmed away to allow access to put the elevator in.
A tight fit and it almost takes three hands to get the elevator attached to the stab.
pic 6:
one inch up elevator (plans call for 3/4" ).
Only about a 1/2" down elevator (there's no way I'm ever going to do outside loops with this plane so 1/2" is plenty!).
I epoxied to the stab in the up position to insure I had sufficient room since the stab has about a 1/4" overlay on the top & bottom to meet the LE of the elevator.
pic 7/8:
Elevator control rods made from 4/40 rod, carbon fiber tubes and 1/4" wood dowels.
I drilled a hole down the middle of the dowel and cone shaped one end and also drilled a hole on the side of the CF tube for the bend of the 4/40 rod to stick 'out of'.
Epoxied slopped on, the bent end of the rod put into the hole in the side of the CF tube and then the dowel pushed into the CF tube.
pic 9:
4/40 rod screwed to the elevator control horn.
pic 10:
the other end will be connected later.
