    Is Sonex the Best Choice

    It's important to note that the AeroVee has few or no actual VW parts. The case has more clearance than stock, and the and heads probably have more meat in critical areas. They are are purpose-built aftermarket units designed for increased bore and stroke. If these things were routinely...

    An old guy finally learns to fly

    It's also alleviated somewhat when you have the controls, which will be more often as your training progresses.

    ATC Services in Canada

    That's in part because Canada has separated ATC from the regulatory/enforcement functions, and doesn't cross-fund one with the other. The user fees in Canada have been reduced at least once, if I recall correctly, and GA interests are actually represented on the board that sets ATC fees.

    Radar Reflector

    Find a broadcaster who's recently rebuilt a studio. They sometimes use 2" copper foil, although I don't know if it's adhesive-backed. The aluminum stuff they sell on a roll at Home Depot is 2" wide, relatively cheap, and works well for gimmick antennas. Probably not marketed well enough to...

    Opposed piston engine

    I couldn't immediately find web pages for specific projects, but here are some examples. Imagine the little shake-to-recharge flashlights, only scaled up.

    LSAs. success or failure?

    For anything but airplanes, it's been a disaster. Those who predicted LSA and Sport Pilot would benefit only the FAA's appetite for control have largely been proven correct, IMHO. No significant LSA rental fleet has materialized, and it's still tough to get insurance on anything but airplanes...

    IRS/State tax request for Airplane just flying by?

    Unless it's a Lambo or a Bentley, cars probably fly under the radar. My guess is that your latter supposition is correct. "Those 'jet setter' pilots won't miss a few thou."

    Opposed piston engine

    There have been glimpses the past few years of people working on engines which used the crank(s) not for collecting and transmitting power, but just to hold correct position on the pistons, then used the linear motion of the pistons themselves in an alternator. Given the efficiencies they can...

    New 406 ELT expierence,,long

    This actually brings up a pretty interesting possibility for an app. Not saying it's all you should have, but a newer smartphone has GPS, decent battery life, accelerometer and network access. It wouldn't work everywhere, but as another layer of safety, could an app be written which would...

    Radar Reflector

    I did a demonstration during an antenna forum at a fly-in of what I call the "CLA Dipole," as in "crap lying around." I stuck a piece of 2"-wide aluminum-foil plenum tape to a scrap piece of 3/4" particle board, used a box cutter to slice a 1/4" gap in the middle, and used two self-tapping metal...

    Radar Reflector

    It's a neat product, but it has its limitations. It's been a while since I used it, but I think it's spec'd for 5 ohms per square, and I got it down to almost 1 ohm with three coats. But you have to find a way to couple to it in some way that will withstand vibration and dissimilar metal issues...

    Training someone who surrendered their certificate?

    It could also be he surrendered it in a plea deal to end an FAA process. I know a CFI who surrendered his instructor's certificate in a dispute which did not involve the violation of any FAR, but brought his judgment into question. He can retest and get the certificate back, and may be back on...

    What is an FAA Ground Instructor?

    About 12 years ago, after I completed a Part 141 ground school that burned through four instructors who were CFIs leaving for regional carriers, the chief instructor told me that if I got my BGI he'd put me to work teaching the Jeppesen Private Pilot course at the school. I didn't pursue it...

    IRS/State tax request for Airplane just flying by?

    Probably not, because it fails to answer the central question of whether it qualified: "Did it spend seven days or more on the ground in Pennsylvania?" They're not going to leave you alone until you can tell them why you're exempt. They may not leave you alone even if you are exempt, until...

    Radar Reflector

    You need a half-wave to resonate, unless you're putting a ground plane under that quarter-wave. If you're cutting foil strips, they'd need to be a half-wave. Regular paint with metallic flakes may not have them close enough together to really conduct. This stuff is good enough to use for a...

    IRS/State tax request for Airplane just flying by?

    Again, you've said he landed there twice, but the question is, how long did he stay? If he lives around various locations, he may have stayed in PA long enough (their state use tax is triggered at 7 days) to actually owe the tax.

    Training someone who surrendered their certificate?

    You missed a step. He'll have to demonstrate his preparation for the knowledge test to a CFI, who will then endorse him to take the test.

    IRS/State tax request for Airplane just flying by?

    That's a really bad idea. Use taxes have been upheld in court, and if it takes six years to get you, they'll add penalties and interest at least as far back as their notice to you. Go online and look up the tax law in that state, draft a logical, dispassionate reply letter, and get confirmation...
