    What is inside the puck of a VOR/ILS antenna?

    Most likely a "balun" as stated here: https://sarasotaavionics.com/avionics/av520 The "cat whisker" type of VOR receive antenna is a dipole, i.e. has two elements and no ground. As such it is considered BALanced. The coaxial cable used to connect it to the receiver is UNbalanced since the...

    Hidden stealth aircraft antenna

    Balderdash! There are many competently designed antennas which operate at well below 50% efficiency due to size and cost considerations. An aviation related example is the NDB transmitting antenna. Here is a link to a paper describing one...

    Cold Start Screw up?

    I have read in several places that some kind of polymer coating is being used to address start-stop operating conditions, for example: https://www.sae.org/publications/technical-papers/content/2012-01-1966/

    Oil drain for piper arrow

    Seems to me that your "quick" drain is more trouble than it is worth. Have you considered replacing it with a standard (non-quick, screw in) drain plug?

    What DON'T I know about paint?

    Clear is available in both enamel and lacquer. I'm guessing you used enamel on the Mustang so it was OK. The Krylon was lacquer so it messed up the enamel color coat.

    How do you talk to a car mechanic…

    What kind of lift do you have? A "real" one where you can stand underneath the vehicle requires a 12'-14' ceiling which rules out most residential garages. I've thought about getting a "Quick Jack" which raises the vehicle about 24" or so, but that still requires the use of a creeper which...

    1966 charging issue

    Normally, the generator light is connected across the cutout relay (inside the regulator) contacts. This means one side is at battery voltage, and the other side at generator voltage. Engine off, zero generator voltage, bright light. Engine idling, low voltage from generator, light not so...

    1966 charging issue

    You have an unusual condition. The light going off means the generator is producing battery voltage. One explanation is that the regulator's set point is 12.6V instead of the normal 14V. I would "full field" the generator and see what happens. This should isolate the problem to either the...

    Need small air compressor.

    Race cars benefit from nitrogen in tires because, without moisture, there is less pressure variation with temperature, thus the handling is more predictable. Aircraft over 75,000lbs are required by FAA to use nitrogen (or other "inert" gas) with less than 5% oxygen to prevent explosions with...

    What to do when you need AGS type glass fuses?

    Not recommended. AGC is 1/4" diameter while AGS is 9/32". The AGC in the larger holder may heat up due to poor contact and blow even though there is no circuit fault.

    OP if you want numbers, here they are (approximately): Full rich 10:1 (cools the engine for climbing) Best power 12:1 (adjust mixture for maximum rpm) Best Economy 15:1 (adjust mixture for peak EGT) C152 same as C172 and basically the same for any gasoline powered engine.
