I had the pleasure of meeting Chuck Campbell. Really enjoyed checking out his very close to plans (and r eady to cover) Pietenpol Air Camper. A very special gentleman. What a treat! Even walked out the door with a neat Pietenpol clock! Oh relax, he gave it t o me! Seriously, I am honored to have spent an evening with my new Pietenpol frien d and WW II veteran Chuck Campbell.

Aside from nostalgia, and keeping the 1930's look (which is a valid reason), I can't think of any practical reason. Bill C.

The safety cable was just a bit too long and I neede d to add more bungee cords to the shocks. The following winter I built die spring shocks and have had no problems since. You don't have to worry about the hassle of checking and replacing the cords every few years. And, I lik e that the springs work in compression rather than the cords being in tensi on.

I am half done my split axle land ing gear but not at quite the shock absorbers. I am leaning towards using s teel spring due to the low maintenance "build, fly and forget" it offers. I was talking to a very experienced tailwheel pilot and instructor (not a ho mebuilder) about it and he recommended bungees. Could I have any input on the pro's and con's of each? How many of you bui lders have made the switch after your piet was built and why? If anything i t might add 1 knot to the cruise speed!

With the bung ees, the nose really dropped when I pulled the throttle to idle. This effec t is much less pronounced after we switched to springs. -- Jeffrey H.

In all seriousness, I think aerodynamic mods are fine if they don=99t add weight and you find it an enjoyable pursuit. After all, fun is why we build these things. However, don=99t expect too much from them and I=99ve often wondered if the extra effort and time added building, is worth an extra 3 kts cruising speed. I mean, when I=99m chugging ar ound for my average 30 minute summer flight, I couldn=99t care less h ow fast I=99m going. The ONLY time I ever wish I had a few extra kts of speed is going to Brodhead, but even then it would only shave off ten-f ifteen minutes or so. That being said. I did spend an extra month fairing the axle and covering the wire wheels. I have NO idea how much it helped having not flown without those mods. The biggest thing I could do to improve my cruise speed would be to fair or re shape my wood struts which have a poor aerodynamic shape, but again, I =99ve weighed the effort against the benefit and decided I=99d rat her spend the time flying her. I also experimented with some teardrop shap ed clear plastic tubing to fair the round cables. I did my landing gear ca bles, then decided against doing the flying wires because it would destroy the vintage look. But I do think round wires make a ton of drag which cou ld be at least halved by sleeving them. I think biggest drag inducers that could actually be helped are: struts, wh eels, strut connections, axle, windscreens, foot pegs, cables. $.02 Douwe This e-mail message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential and privileged information.

They were , if memory serves, around $85 or $90, cheaper than I could find anywhere else.
