My observation. If you attempt a float takeoff with aft CG the plane will porpoise. The one in the video does. Given space you can get if flying in...

Aft CG.

Or a regular guy found an unusual gust after an unusual approach on a very unusually windy weekend. I don't know the plane or pilot but I'm in no...

Mike taught me that. He also has a tube with castle cuts in the end that he heats and spins with a drill. I prefer the copper tube myself.

Drill? Pass. Use a small soft copper tube and sharpen the edges. Heat with a torch and melt the holes. You can do several before the heat gets to...

I'd be careful about too much AOA. If flat the airplane will decide when to fly off. With the nose high it may suffer from premature ejaculation, and...

Find a local plastics dealer. Depending where you are a glass shop may also have it. Lexan is polycarbonate. Very susceptible to scratching. Very...

My version of a spreader bar. Different shackle holes for different airplanes. Made from scrap steel and shackles I had laying around. Sent...

My coolers are 3-1/2" thick. I believe oil is spread across the full width dispersing heat through all the webs as it travels through the cooler from...

Having never seen a section view of an oil cooler's cooling core, is there a reduction in efficiency when the cooler is laid horizontal rather than...

No idea, but it can't match the flow through a fully exposed cooler on the rear baffle. But you can duct air from other places than just the top...

A 3" blast tube provides 7.065 sq in of area. Changing to 4" would provide 12.56 sq in. My 9 vein Niagara coolers have 22 sq in of cooling area each....

With that oil cooler installation you could add a pilot controlled scoop on the top cowl and force more air through the cooler without stealing any...

Maybe owner maintenance should require owners taking a class? Get interviewed for competency like a Repairman Cert requires? Not every owner is...

Paralysis by analysis.

If you've never removed a tired engine and replaced it with a new engine you don't know what you're missing. No, seriously, you don't know what...

15 years ago I would have agreed with you. 10 years ago when I finished my -12 my attitude was changing. 5 years ago when I decided to build an exp?...

My opinion is that your comments are incorrect. The Cubs fetching the highest prices are experimental. And as the owner of one of that category...

Do a member search for guys who spent time in prison. And liked it.

Airflow Performance 200A. Their most current high performance servo. The zero leak down is big. Guys with the previous iteration were adding a purge...

Starting old school fuel injection with old school mags must be different than new tech fuel infection with electronic ignition and auto spark plugs....

Parachute cord. Cheap, easy, very effective. With a -12 just shove it in back. You don't have to act like the -18's lack of space is something to...

Crappy ignitions. Add a good electronic ignition and hot start problems will be a distant memory.
