  I have a manifold pressure gauge in my KR. It's nice for fine tuning throttle settings and calculating percent power, but it's only there as a personal preference and is completely unnecessary without a constant speed prop. Can't say that I would be able to diagnose valve issues or engine

You are allowed to expose yourself to lead if you choose. I think most of us have, including me on numerous occasions. But after watching a friend's illness with lead poisoning from bead blasting aircraft cylinders IN a bead blasting cabinet, I don't work with lead anymore without adequate

  Ron, That's the way it's supposed to work... in theory. The reality is that many FSDOs simply don't have the manpower to do amateur built inspections. I have seen guys get held up for a year waiting on FSDO to do an inspection because they wouldn't cough up the $500+ travel expenses to

Bob, In the US, a DAR inspection is the only FAA inspection required on an Amateur Built Aircraft, and is only performed after the aircraft is completed. All other inspections are typically by an EAA Tech Counselor and are strictly voluntary... i.e. not required. Even the Tech Counselor

You can order direct or through your favorite aircraft parts vendor. If your spring is mounted at a non-standard angle, they will be happy to make one to fit your plane. Choose between the 4" solid tail wheel or the 6" semi-pneumatic tailwheel (hollow inside to make a bit softer).

Just notch a step into the skin large enough for the false spar to sit in the skin, then scrub the foam out from between the layers about 1/4" deep. Fill with Flox and slide the false spar into place. Your call whether you want to add a layer of glass to it while the flox is wet or not. I

Unsanctioned by USAF? Yes. We only did that when the inspectors weren't looking. :o) For others, running a tap through the metal self locking nut plates does not destroy their self locking qualities. They don't just bind as tight, so they don't destroy the threads on Stainless screws or

Either method works just fine. I chose to counterbore the hinges and used flush screws with the screws offset between the aileron and the wing.  Like Larry, I also floxed a set of #8 nut plates to the back of the mount holes to make them removable. One note on self locking nut plates like

What Chris describes is not at all unusual. A number of aircraft fly better in an aft CG as the elevator gets too heavy with a forward CG. A C-182 is a good example. A 200 horse Muskateer is another. It flies better and is easier to land if your CG is a bit aft simply because the elevator

The Mode C veil is not going to go away. Instead, in 2020 you will have an additional requirement of either a Mode-S transponder with extended squitter and GPS position reporting encoded into the extended squitter (known as 1090-ES) to replace your Mode-C transponder, or you can have ADS-B Out

Static balancing controls is always a safe addition to the plane, but is still an addition of weight. It's probably worth noting that the plans do not call for static balancing the elevator. I have flight tested the original design elevator to 225 mph IAS with no indication that it might
