Kevin, The rudder pedal position is mostly a function of the length of the cables. I found an easier solution lengthening an aileron cable by replacing the standard turnbuckle with long one. The long turnbuckles, available from ACS are 1-3/4" longer than the standard. Given the geometry of the rudder pedals that would move the pedals ~ 3" closer to the firewall. Craig S.

I (duh?) did not calibrate the senders before putting the wings on the plane. I did check the resistance and both went from 73 to 10 ohms. Unfortunately, I found today, when calibrating the senders for my EFIS, that the right tank sender doesn't register the 1st gallon and then maxes out at 8.5 gallons. The left tank starts right away, but maxes out at 6 gallons. I am really not looking forward to trying to extract and adjust the bends in the float wires through the access hole, but I really don't want to have displays that only register 1/2 the fuel in the plane. (Even though it will be OK at low fuel levels.) I do have a fuel flow and totalizer function. Anyway, I am looking to hear if anyone else has had this problem, and what the fix was? Maybe I installed them upside down?

The float does hit the top of the tank at about 10.8 gallons so it will be against the top of the tank above 10.8 and you cannot make it read correctly above that. My Dynon 180 seems to be extremely accurate between 0 and 10.8 gallons. I made a dip stick to check the fuel level on preflight. It takes about 7 gallons in the tank for it to be visible through the filler port.

I have a couple for problems. One is how to hold the tip in place while drilling, as there doesn't seem to be a way to clamp it. The other is that it looks like I'll have to trim the skin around the front of the tip to prevent it extending past the curve of the fiberglass. Is this normal? If I install the tip so that front of the skin blends smoothly into the tip, there is only about 4mm of space to rivet the tip. I know this isn't very clear. Trying to come up with a better description.

The important thing is that the gauges be accurate at the low end in order to indicate when you are getting short on fuel. The "fix" is to make a calibrated dipstick to tell you how much fuel you start out with for fuel planning purposes. The gauges will give you a reality check on your fuel planning. Once you get your fuel totalizer function calibrated, that will most likely become your primary fuel monitoring device with your dip stick to verify the starting point and the gauges as a reality check. I have the 12 gallon tanks on my Zodiac. My fuel gauges can only read the last nine gallons or so in the tanks and my dip stick can only read the first nine gallons. If I have less than three gallons in the tank, the bottom of the tank directly below the filler cap is dry. With the 15 gallon tanks, you will probably have the same situation, the float will hit the top of the inboard end of the tank with about nine gallons in the tank and the bottom of the tank below the filler cap will be dry after about nine gallons are used.

A flat surface held up against the wing tip should make contact with the cut off end of the spar extension and the wing skin around its entire circumference. Once you get to that point, the fiberglass should fit nicely. The fiberglass parts do have a tendency to sag out of shape after some time laying on the shelf, so you may have to apply some gentle heat to them and bend them back into their correct shape. When I did my wing tips, I shoved the fiberglass parts into the nose of the wing until there was a minimum of gap and then put a couple of clamps at the rear of the fairing to hold it in place. Even then, I had to hold the part tight to the nose skin as I drilled the first few holes in the front of the part and got some clecos in place.
