Pushrods

In the opening of the wing saddle, as far front as you can reach attach the pushrods to the side of the fuse again with a drop of goop. This will leave the area directly under the wing unsupported and likely 1/8th or so from the fuselage sides. In the middle of this area make a small support from scraps of balsa and attach with CA to fuse sides and pushrod on both sides.

NOTE: Do not force the pushrods to the sides of the opening to attach. Sharp bends and carbon pushrods do not get along and will create a bind eventually.

Time to move back to the tail. I install the rudder control horn directly in line with the center of the boom. Mark the location on the rudder and trim the fiberglass from the slot. I install the control horn through the first layer of skin and wood to the skin on the other side. Scuff this immidiate area lightly and place control horn in slot. When aligned, glue with thin CA. This will hold the horn temporarily and harden the wood in the imidiate area. When satisfied with alignment, fillet with thick CA. You can use masking tape to temporarily hold the pushrod to the boom. Make a nice smooth transition down the side to the correct location with the push rod. Make sure to keep it smooth, no sharp turns or kinks. When you get to the end the pushrod will have to move away from the boom to get to the correct location on the control horn. This needs to be supported with a small fillet of balsa. Remember, the only unsuported part of the pushrod will be just enough to compensate for travel. I use two sticks rubber banded together on each end to hold the control surface straight per the left photo below. I like to use an L bend on this side of the push rod and use one of the Dubro tiny parkflyer keepers or a tiny piece of wire insulation and a drop of CA to keep it on. attaching IT permantly, make sure your servo is electronically centered.

Repeat the process for the elevator push rod. You should now attach the pushrod housings to the boom. Every few inches you can put a tiny dot of thin CA till you are completely satisfied with alignment and then wick some CA along the length of the housing being VERY careful not to get any on the carbon rod.

You now have a fully functional fuselage and all that remains is to install servos and wiring in the wing and balance and set control throws.
