What is ERTP flying? I'll let Pat March tell you. He's been into this for a long, long time. If the pictures and ideas interest you - and they should if you live where the weather's not always good, then here's a way to fly indoors. Pat runs the Skonk Works, and their symbol ain't no cat!
In the late '60s, I thought I had invented ERTP. But the English had beat me to it. They had a twin engine Vikers Viking, with landing lights, running lights, retractable landing gear and working flaps flying at an RAF charity function as early as 1945. This machine used home made AC motors!
This is a photo of the plane Pat's talking about. It is a Vicker's Viking and was flown at Dorland Hall from 1945 through 1946. It had a span of 40 inches and made over 1000 flights! It was created by the staff of Aeromodeller. They also created a DeHavilland Vampire with the ducted fan unit being electrically driven. The Vampire also had a retractable undercarriage. | |
To the left is picture of the
Skonk Work's mascot. Pat continues - You need not make your own motors. We
have a variety of good low voltage dc motors for you to use. Pylons have
come a long way, too. Skonk Works provides one that allows you to operate
elevators on your models. Many multi engine models have been flown. Ducted
fans are practical, and we have two for you to choose from.
The educational value of ERTP is incalculable. Novices learn not only practical skills in making their models, they also get a painless introduction to electrical theory and practice, as well as solid knowledge of geometry, some math, and physics. Participation in ERTP modeling has lead to solid careers in engineering and toolmaking. All this while having fun! | |
We invite you to get our
catalog and look through it while letting your imagination run free. You
will think of odd possibilities that you just have to try out!
We want to hear of your successes with ERTP. We are also concerned when something does not work to your expectations. New ideas are welcome, but don't be surprised if I suggest that you do the development work! This can be rewarding or extremely frustrating. Most developments exhibit both aspects. Phone calls are welcome. You can usually get me from 7 to 7 (Eastern), 7 days a week. I love to talk modeling. |
Some of my customers communicate by E-Mail. This is quick and economical. I check my computer at least once a day, and will respond to any inquiries or thoughts that you send me. You can find me at insideman@worldnet.att.net - Happy Modeling!
