These are PA-11 spars. The holes seem to match the original Piper J-3 spars. I did not take precision measurements, since the ferrules were already...

Yeah. At 500 feet, you either have to be in the process of taking off or landing, or very sure that you are 500 feet or better from the nearest...

Well, I am replacing Dakota spars with Dakota spars. Before the wing got bent, it fit perfectly. I double checked the front spar, thinking I had to...

I picked up a Champ several years ago - the guy said he used lightweight fabric. I almost panicked. To me, Stits always had glider cloth,...

Keep it stock. Next time you recover, consider that new lightweight Stits. I had no idea they had changed fabrics.

I think by definition Vx gives a better gradient than Vy. It is about 50% better in my Stroker J-3. Lifting off above liftoff speed may be good for...

Robbie Grove has a Tango Cub that actually works. Not sure that any of the others are all that great, so he may have setup suggestions. My...

Yep. Talked to the original restorer. Poly Tone white under the yellow. I should be able to match the original - and the Wag wing rotator arrived...

They are required to give you a reason in writing. I could look it up, but it is on the very first page of one of those Technical Orders.

One can easily fly an aircraft without a license or ferry permit without getting "caught." But here in the lower 48, your insurance does not cover...

No kidding? It is clear he used Stitts fabric and Poly Brush. Tell me more. Logbook says Aerothane Cub yellow. His IA approved several major...

I read my first one in 1969. Bought stuff from Ray Stitts himself. My airplane is approved for Stitts through silver, then anything. Later manuals...

Will they do as with DPEs and have everybody go to OKC at their own expense, maybe even for yearly conferences? Will you have to flunk half the...

Thanks. I was just going to put a plate in there, but the flanges will add to the strength, and the leading edge has to come off anyway.

Neat thread. I had all the J-3 bulletins - Piper would send them for free at the slightest provocation. I have long since misplaced both sets sent...

Be polite. Call them once a week, and get a meeting to "discuss." This has been working for me, although some of the brake conversions have taken a...

I have seen folks regrind what looks to me to be very serviceable tappers and cams. I think, without any evidence, that regrinding removes something...

Never had one outside an airline environment. Feds come by my hangar regularly, never ask to see anything.

Yow! I have never seen any that bad.

I heard that rumor about field approvals. I got five last week, saving the owners thousands of dollars in DAR-T time.

I no longer fly in the rain with my SL-40 and PM-501. Have no idea what is happening, but it goes into transmit mode. Mark Scheuer assures me it is...

If you fly 90 hours a year that is almost twice a week. Did you actually see the rust? My Decathlon flies less than that, and so far after 15 years...
