RE: ZIROLI 98
Wings (cont)
3-piece conversion (cont)
After sanding an angle to the aircraft plywood, I noticed there are 6 ply's and not 5.
Center wing (cont)
The left half got sheeted via the same methods as on the right half.
My nav/landing lights came in.
Left wing (cont)
The wing was placed on the wash out risers and the top sheeting was added.
Center wing (cont)
The front ply spar that span several ribs was epoxied to the ribs. The back one will be done after the flap hard points are in place.
picked up some hardware at ACE hardware: wing bolts and spacers for the main wheel axles.
The main gear was attached to the G10/ply mount and dry fitted to the wing. There is a small angle out from perpendicular on the mains but acceptable for me (that 1/8" thick spacer can be thinned, if needed).
Main gear:
I finished drilling/tapping the holes for the gear, being aware that the center hole (inboard) needs a shorter screw as to not damage the air cylinder (also do not drill too far when drilling the hole!).
The last back wing incident spacer was epoxied between W1 and W2.
Outer left wing (cont)
The aileron and flap was glued using the measurements from the right wing to get identical moving surfaces.
Two pieces of 1/8" thick lite ply was cut for the aileron control horn hard points
Servo trays:
I needed to make more servo trays so I used old lite ply left over ribs.
I find making the parts in steps insures better accuracy, ie, the servos will fit into the tray.
Being the servo mounting brackets are 1/4" thick, I made tic marks on the side ply and epoxied some 1/4" square spruce to them to make slots. I used a piece of ply to push the side ply and spruce against to insure the ends are all aligned.
The sides are then epoxied to the base.
