    Fly with expired transponder to get it certified

    My transponder expired a month ago. There is no shop at where my aircraft is currently kept, so I need to fly to an airport 20 minutes away to a shop. What procedure should I follow? Call ATC when airborne to request a deviation? Or do I need to file some application with FAA/FSDO beforehand...

    Experimental aircraft purchase - Do I need to pay sales tax and how? (California USA)

    I am buying a small experimental aircraft in California USA. The price is around $6000. It is a registered N-numbered aircraft so I will have it registered under my name when I have it. My question is: do I need to pay the sales tax? Do I just wait for the bill to come from the state agency, or...

    How tight should the mounting bolts be tightened to?

    I am finally at the stage of really mounting the engine. I am wondering how tight should the mounting bolts be. As you can see, castle nuts are used so the tightness does not affect how secure it is mounted. I replaced all the rubber cones (the black cushions). As they are new they can be...

    Surface paint - is orange peel a bad thing?

    I am about to hand paint my aircraft. There are some gentleman on Internet and EAA webminar sharing his procedure of the painting aircraft with household latex paint.

    Covering ultralight wing with undercamber

    I was looking at my wing the other day and noticed that it has some undercamber. The original construction for Hiperlite use a pre-sewn envelope for wings. That fabric is held down to the rib caps by some double sided sticky tape. The Poly-Fiber manual stated that the cement is good for sheer...

    How do you tune the engine?

    Not "What do you tune on the engine" (I need that too), but "How do you tune the engine". Do you stand right by the big propeller arc, strong wind in your eyes, loud noise in your ears, screw drivers and pliers in hands that are just inches away from the chopper blade? Or is there some better ways?

    How should I lay fabric here?

    I am dry fitting the bottom of the fuselage, trying to figure out the challenges first. So I have this question on what I should do here. So basically this is the bottom of the fuselage. The whole frame is upside down. Engine (unmounted now) will be on the right hand side, and tail is toward...

    What is this piece on ignition?

    I am working on a 2-stroke engine with integrated ignition (Zenoah G50, see this thread on ignition). There are two small ignition components that are mounted on the engine mount. They are pretty small, about 1 inch or so across. For reference, the mounting screw on the picture is #6 screws...

    Magneto coil or stator, which way?

    Continue on my journey with Zenoah engine. I have finally got a puller to pull out the flywheel. There was a magneto coil plate down there, and I have a replacement stator (I believe for the same engine). My original plan is to replace the magneto with the stator, and go with a CDI. However...

    I am working on rebuilding a Hyperlite SNS8. I am fairly new to this and am wondering how to connect the edges of fabric cover to windows? For example, this first one seem to have those transitions right around a tube of the fuselage. But how is that transition done? Any detailed pictures or...

    Can you test run a 2-stroke engine on bench without load?

    There are so much unknown with the 2-stroke engine I have, I am not even sure if it will run. So I am planning on bolting it onto a temporary bench and working on it piece by piece. That's very much like how I worked on the engine on my bike, getting it to stable idle, rev up a bit to make sure...
