Have really been enjoying the soaring history thread.

My dad and I built an Oly 99 around 1972. Never got to fly that one, as we sold it to help finance a radio system. He and I built another around 1974 or 1975 which I flew in some of the MESS (Metroplex Electronic Soaring Society) events in the DFW area. in the mid 1970's.

I went to work for the Hobby Market mail order R/C outfit in Fort Worth while in college in 1975. As I recall, Airtronics came out with the Aquila around 1975 or perhaps early 1976. I got one from the first shipment and had the second one flying in DFW. Bob Elliot from EK Radio had the first one, a kit gotten early from Airtronics.

The Aquila did not live too long. It was "shot down" at a soaring event in Breckenridge, Texas around 1977 by a guy leaving his TX on in the impound...sigh. I still have the wings and tails which are restored and in perfect shape, plus a glass fuse to replace the destroyed wooden fuse. It will fly again one day!

I also had a Graupner Cumulus around 1975, as well...nice flying model. Lost it to radio failure around 1976, as well...my state of the art MRC F710 system let me down.

Le must have had a crystal ball. He was predicting bigger planes back in 73'.
The Draggin' Fly looks like another V tail for my hanger.

Ya know.. One of the best parts of this hobby 20-30 years ago is that it was very affordable. I had a Windward. Yup, paid $25 for it. Flew it in my very first 2m event. Then whilst in college I flew it in between studies. So for less than $50 one could enjoy the hobby...

True, the kits were very affordable when I was a kid but I remember radios being WAY out of reach 30 or 40 years ago. Thats probably why I was into free flight back in the early to mid 70's. In the late 70's I bought my first rc glider kit, an Aquila. Seems to me it was 60 or 70 dollars (if memory serves) and when I was 17/18 that was a bit of money.

I did fly an Avatar, it belonged to the designer if I remember he was Willie Richards and was a SULA regular in the late 70's. It had a stepped fuselage that kind of hid the tow hook. This was a familiar layout in the early days showing influence of the RCM Snipe and would later lead to the Questor and others.

Didn't have an Avatar, but I did have the 100" sister ship "Curio". Really nice kits by Milt Swan. I believe Milt was also cutting parts for the SoarCraft kits, back in the day.

BTW Milt is still in the wood business, only it's high end hand tools. Check them out at: http://www.swantoolusa.com/

R/C Soaring History Question

At the 1985 AMA (the LSF wasn't involved yet) Soaring NATS in Massachusetts (those were the days when the NATS moved about the country) , a most unusual sailplane competed. It featured electrostatic sensors that detected lift and was uglier than the much-maligned Shuttle. I thought I had some pictures of it but cannot seem to find them. Can anyone else with a good memory comment on this sailplane?

Helmut Lelke was the flier. I never knew the plane had a name though. He was a Charles River, CRRC member, a search of their site might bring up some info.

The 1985 NATS was just before my time, but I did get to see Helmut fly this model at one of the first contests I went to. It was probably one of the first high performance designs I had seen and one of the first high wing loading sailplanes I had seen. He intentionally designed it with a flat wing to demonstrate the stability system. From what I recall, the sensors had a radioactive component. I always thought that was pretty neat - certainly opened my eyes to what is possible if motivated enough.

Here is one of Helmut's more recent efforts http://charlesriverrc.org/articles/a...lke_asfwpp.htm

The "electrostatic autopilot" came out in the early 1970s when I was in college. There was a how-to in one of the model magazines, complete with schematics and component part numbers as I recall. I always wanted to build one, but never did. Someplace I have a copy of the articles. One reported "feature" when used with power models was that once in a while the model would briefly flip inverted right after takeoff.

LSF was almost out of business in the 1980s. The last LSF tourniment before 1980 that I rememberwas1979 at Lockport. I flew in that one. The next LSF tournament was in 1992 at Vincennes. It was followed by anothe one at the Lawrenceville Airport in 1993 before moving to the new AMA field at Muncie in 1994. LSF took over the AMA Nats soaring events in 1995 and has run it every since.
