I had to make my own. It was a lot of work, but satisfying. There are more left ones in the system since they are used on Tri-Pacers.

That's where the two position control valve for the Sensenich C-2FM two position prop goes. The oil to the prop is connected where that allen plug is located. The vacuum pump drive is on the upper...

This is another method. Balsa wood faired and glued to the surface leading edge, covered with a fabric tape. Does it work? Don't know, as it was installed before the first flight. It does close the...

Bigger footprint for soft ground but not too large a diameter for the low horsepower. Too large a diameter can put you on the wrong side of the power curve when you have a load.

Also there are no record keeping requirements. https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ftse1.mm.bing.net%2Fth%3Fid%3DOIP.m9MkCmdkEJ-eXOg7pkKgJwHaG7%26pid%3DApi&f=1

Here are some closer pictures of the attachment fittings. That hollow tube is the axle. Notice the grease fitting for one of the attachment locations.

Does anyone...

Not a Robin as there is no provision for an axle.

It's a mystery Glenn. These are one piece aluminum. The shape of the attaching hardware seems to go on something like this P-26 which first flew in 1932.

A mystery!
What did these wheels come from? These wheels were on an airplane in the shop of the Gardner Massachusetts high school at the beginning of WW2. At some point in time the entire airplane...

Was there any speed change? With a fixed stabilizer and a trim tab on the elevator, the two surfaces are not always perfectly aligned. Therefore there could be some tendency for air flow along the...

Like this. When the surface moves it will remain the same tautness. The way you show it, it will be tight when the surface moves one direction and loose when it moves the other direction. There was a...

Soy,
Do you have a local person who is good at welding thin aluminum? Clean it up thoroughly, weld it back together, add some reinforcement, fix the rivets. Make certain to install those support...

Make sense to me too.

I saw an airplane with leading edge bumps as described in your link. I seem to remember it being at Birchwood or perhaps Merrill? It was orange in color, never saw it fly.

The slot is the gap between the slat and the wing leading edge as in this discussion. On the Cub flap system there is also a slot between the wing trailing edge and the leading edge of the flap.

That doesn't mean the buyer got a good deal nor that the airplane was any good. Auctions frequently gather more than an item is really worth.

How many of those have been installed due to the actual performance improvements having been proven to the owners? OR have they been installed just because "every one installs them" and/or "I spent...

It's always interesting to listen to aviation pioneers speak. I do have to respectively disagree with Otto Koppen on his premise that differential ailerons do not improve aileron performance. I...

I am one who gets excited about barn finds. I bought a Stinson SR on floats once which was a barn find, after it's owner took a pistol to his head while drunk. This Cub needs caution since there is...

I haven't flown a Helio on floats. But, I did have a side by side competition with one flown by a long time Helio owner. I was flying the Twin Bee. We did side by side take offs on land and water as...

My 2 cents ........ skip the slats, but do install the nut plates since they go under the LE skin. That way you'll not feel any pressure to do it now, particularly since your description of use...

Hmmm? Bush wheels? Water ski attempt gone wrong? It looks remarkably intact for taking out some electric power lines.

You're off to a good start, enjoy your ride. Your time will come before you know it.

An observation. Now that it is bug season and hardly a flight is made without there being any bugs to clean off the wings after a flight, I have noticed something. I seldom find a bug on the swept...

Lack of low altitude radar?
