Re: Is exterior of floor covered or painted
34KP does not have a stringer running down the bottom. Flat plywood, fabric covered.

Re: Is exterior of floor covered or painted
N34KP is covered over the plywood on the bottom. For what it's worth, plywood covered wings are generally covered in fabric, for abrasion purposes.

Re: N34KP's engine
Well, the Ford ran great after I got the new ignition system figured out. Just prior to leaving for Brodhead it started shooting oil out of the seal on the prop end, so I ended up driving to Brodhead. When I returned I thought I'd try an experiment to see if I could stop the leak. My theory was the ...

Re: Center section tank straps
One suggestion, if you haven't already built your tank. If I were building a tank I would put the filler on either the left or right side of the tank instead of the middle. When filling the tank as built it is difficult to see the fuel level as you fill. On N34KP this has resulted in numerous overfi...

In the case of N34KP the tank is held in by the aluminum tank cover with a row of screws around the cover. There are wedges under the tank and felt strips on top of the tank for a snug fit in the center section, for no tank movement. IMG_20220124_124011.jpg IMG_20220123_133046.jpg IMG_20220124_12493...

Re: Elevator vs rudder control horn
Rubbing against the leading edge of the horizontal stab is a common occurrence. If you build to the plans it is going to happen. Several builders, including the builder of N34KP have raised the bellcrank behind the pilots seat up to gain cable clearance. It is a minor thing and in the case of N34KP ...

Oscar. They are 6:00 x 6 tires. The new wheels are narrow and even though they say they will mount the 8:00 x 6 tires I couldn't get the wheel half's together without pinching the tubes. I ruined one tube trying. I had a hard enough time with the smaller 6:00 x 6 tubes.
