Welcome to Stefan Vorkoetter’s web site! I’m a private pilot and model aviation hobbyist, slide rule, calculator, and fountain pen collector, electronics hobbyist, Hammond organ enthusiast, and software developer living on a Fjord horse farm in Ontario, Canada. This page is a gateway to the ever growing collection of articles I like to write describing my projects and hobbies. If your interests coincide at all with mine, I’m sure you’ll find something useful here.
In-depth tests, reviews, and discussion of batteries, chargers, computers, and gadgets I use.
DIY projects and advice for hobbyists, experimenters, musicians, and aviators.

Over 50 articles demystifying the design, construction, theory, and practice of electric R/C planes.
Aircraft, pilot gear, aerial photography, flight reports, and all things aviation!
Building a Volksplane
Follow my progress in words and pictures as I build an Evans single seat VW powered Volksplane.
Understanding, maintaining, and modifying the Hammond tone-wheel and vacuum tube organ.
Repair, programming, and use of HP programmable calculators from the 1970s to today.
My collection of slip-sticks and whiz-wheels, the calculating tool of choice for 350 years.
Pens and Watches
Vintage and modern fountain pens, inks, paper, and mechanical wrist watches.
Articles and papers on other topics that just don't fit neatly into any of the categories above.
I recently purchased a Sekonda branded mechanical alarm wristwatch, made in the USSR in the 70s or 80s. In addition to needing a complete overhaul of the Poljot (Полет) 2612.1 movement (which I will cover in another article), the acrylic crystal was badly scratched. Here I describe how I restored it to like-new condition.
