Is this the correct angle? Mike Cuy, Jack Phillips, anyone with wood gear and a tail wheel, did you make the gear taller so you could get the "deck angle" of 12 degrees when you added a tailwheel. Based on a sketch I made tonight, I don't see how you could have done it (added the height of a wheel) without making the main gear taller to compensate. I get slightly less then 7 1/2 inches between the bottom of the fuselage and ground (where the wheel would be). I'm trying to use the plans A frame and coil spring design. Perhaps this is a good reason to use the leaf spring design like Mike did. I guess this question could be for anyone who added a tailwheel as it's more of a skid vs. tailwheel problem. So, do I need to add height to the gear when I add the tailwheel?

Ya just cant beat a nice flying Cub. I walked out of the house this morning to 74F. at 11:30am it's still only 78F. I just dont know how to act! Thats about 10-12 degs below what it usually is by this time of day. I suffered a heat stroke a year ago today up in Savannah, GA and spent 3 days in the hospital. It's true what they say, that after a heat stroke your tolorance to heat is greatly diminished....or I'm getting older. Probably a little of both. I've been in Florida almost all of my 53 years but the last couple of years the summer WX and humidity has really been working on me. I'm ready for some cooler WX. Have fun in the cub!

I have steel gear with spoke wheels that are about 26" tall (19" rims). I really like the high angle. The runway is totally blind in the flare but when I land 3-point it is all done flying for sure. I've learned the trick to getting no-bounce landings is to definately have the tail at the ground when the mains are even though it seems to be a very high angle. I do know that Frank Pavliga lengthened his wood gear somewhat to get a more 'correct angle'. This is because the "Flying and Glider Manual" wood gear was designed for the shorter fuselage. When you go to the longer fuselage the gear would need to be lengthened somewhat to maintain the same 3-point attitude. Frank and I have nearly the same deck angle. Others have less though, and seem to really like it too.

A-65 engine mount is 1" longer than plans (just a little extra without losing 'the look') Axle is 1" forward of steel gear plans. I have 14.5 gallons in the nose so depending how much fuel I have really changes tail weight. Doesn't seem to be a problem though. All of these were just compromises I came up with in talking to people who had been there before. I'm really happy with these measurements although I think they could differ some and I'd still like it. Just remember that one change leads to many more so try to keep the changes small and few.

The "Dieselis" engine... comparable in weight and output to the old Ford Model "A" and available in Europe. (http://membres.lycos.fr/dieselis/ ). Keep us informed as to which powerplant you decide to adapt to the Pietenpol. Will you call it an "AriaCampeggiatore" or "Campeggiatore Dell'aria"?

It would be a mistake to insert the spoke into the chamfered side of the flange. That would result in a sharp-cornered stress riser where you don't want it --- right at the elbow curve. Seating the head in the chamfer is good cosmetics, but bad engineering. Good wheelwrights know this and won't do it wrong unless you insist. Ask Buchannans to mail you one spoke of the type you intend to use. Then machine your hubs accordingly. Don't chamfer the flanges on both sides, as that weakens the spoke/flange junction. For all you guys who did it wrong --- not to panic. Of all the things that can go wrong with an undercarriage, spoke failure at the elbow should be about priority "Z" on your worry list. I've been eying the temporary rim and tire from a retired Ford Escort, the engine donor for my Ford/Scout inverted powerplant project. Cut the center out, leaving a bare rim. Machine a one piece aluminum hub and lace it to the Escort rim. Seal the nipples with some super goo, mount the tubeless temporary tire, and add air. Presto --- a beautiful, poorboy set of lightweight, classic airwheels. Sound too good to be true? Hmmmm..... Happy landings, Mike Fisher Talkeetna, Alaska Dan--- you can request various size (they use gauge sizes as I recall) diameter spokes from Buchannan's and you have the choice between steel, chromed steel, stainless, etc. I drilled my holes for the spokes and then used a countersink bit to accept the head of the spoke which has a taper and that helped seat the spokes nicely in the hub.

I remember when I first flew the Cub (about >10 years ago) how strange it felt, and how hard to get the flare right, and >how hard to see. Well, my first supervised solo was in a J-3 off of grass, at Tim's Airpark north of Austin, TX in 1971 or thereabouts. It rented for $8/hr., wet, solo. Since I had been told there would be no forward visibility after the flare, I never thought about it and have always taken my cues from the side peripherals. It feels very natural to me. It also felt very natural to land the Cub in zero wind but in a crosswind, it was a bit squirrely. The one thing that felt funny was having the stick so high up in my chest, but maybe that was just me. The Cub taught me to slip, how to dance the pedal dance, and how to land an airplane without power, which has been a very valuable tool all of my aviation life. My instructors for my first 20 or so hours never let me use power after we chopped it abeam the numbers on downwind (except to clear the engine) and anytime my instructor was aboard and we'd be turning base, I'd hear him ask me, "high or low? Fast or slow?" which caused me to check my airspeed and position relative to the numbers so I could adjust before it was too late. I have yet to translate that experience to the Piet world but hope to do that before Labor Day. Taxi testing of 41CC next weekend, if the Lord wills it. PS- I just viewed the first segment of "Building NX770CG", and it's good stuff. An excellent addition to any Pietenpoler's collection. Hope to fly with Experimental Seven Zero Charlie Golf one of these fine days, and to call "SMOKE ON!" to good old Chuck.
