    Sounds like it would work fine and be quite safe, and maybe even be classed as a minor alteration - but I bet there are folks who would freak out with the extra holes. My understanding is that the...

    I had to look up AKA. Does it have an Alaska connotation (AK)?

    It really does not take good brakes to lock up a wheel at low speed. Even a crummy cable operated brake will put a Champ on its nose if you jump on them at low speed. When the tail comes up, get...

    What an interesting topic. I am aware of one 160 HP on an 18 (a PA-18-95 converted). I have never seen the logs, but it goes through annual easily, and has for two decades. One relatively...

    Big tires really don't change the angle all that much - you can get the actual angle change by using the arctan function in your hand held. With big tires your CG goes up, with very little offset...

    By the way, the scenario is this: you are in the parking lot, see a 3 year old darting out from between the cars, and all four wheels screech. Everybody in the parking lot glares at you.

    Momentum, huh? I cannot remember much, but wasn't that mass times velocity? Put more fuel up there, and that equation gets bigger. I really cannot remember angular momentum, but I could look it...

    Nose impoverished? Is that because a bent prop means an engine teardown with all the resulting red tags?

    Needs to be stressed, because it is not obvious - a very low speed sudden application of...

    I am 80. I am cultivating young friends who will pull the stool away from the Cub door - come to think about it, I bet I can maneuver around said stool. Also have my friends ready to tell me "Bob,...

    Maybe, but it still doesn’t buy lawyers. For a good lawyer in an injury situation, think “$100 Grand” to start.

    As to expenses - for us it is $25/hr fuel, $160/student for insurance (we require 5...

    Where were you guys when the discussion was single engine along the coast from Seattle to Anchorage? That run scared me looking at it from a jet at 35,000 feet! Talk about cold water and no beach ....

    We do very low key J3 dual only. The aircraft is long since paid for, so I carry liability only. It was $1400/year through some weird underwriter, but this year they wanted 25 hrs m/m for students....

    I have used decals, and am now using plain old India ink and Leroy templates. The secret is a light overcoat of rattle can clear, followed by multiple coats of Future Floor Wax applied with a Q-Tip.

    I have a teeny bit of experience in advanced avionics - rated in the A-320. Admittedly, that one is almost an antique.
    Every now and then I get the "pleasure" of trying to figure out a 430 or one...

    Yes. Marv is behind my Cub hangar -I am not his best customer, but I bet I have bought a headset a year for the last three years. In, and out. The 10-13.4 has a flexible boom that always stays put...

    EarthX recommended the “Optimate” Charger. No idea whether it is best - my motorcycle battery charger does the job much quicker. Let me look for the Voltmeter - I have it on a switch, so I can check...

    That really is strange. The Univair gear fits the 1946 J-3 and apparently all subsequent Cub types through the PA-11 and PA-18-150. Hard to believe the military had them change a dimension by 3/8".

    Depends. A student with a Waco was ready to sell because he could not hear the tower with his Bose ANR headset. He tried the DC 10-13.4 and decided he could keep the airplane.

    I use the 680 and the 545 for engine start, small Continentals. Very happy, but I have those neat voltmeters you can buy on Amazon set up to check voltage. They are necessary for the EarthX we use...

    We put the Grove kit on the instructional J3 and ran 26" tires for a half year - appearance only. Even at 20 psi they were not pleasant on pavement and we could feel the performance hit. I put used...

    I have not had problems with non-tautening Butyrate. Multiple coats, and my wood stringers from 1969 are still dead straight.
