A note about Quadras. Ron Schettler of Edmunton, Canada was the first to use a Quadra engine in a model plane. For about a year previous to this, a group of modelers in the STARS club in Olean, NY were attempting to fly a squadron of 1/4 scale Bristol Scouts using an assortment of engines, geared Webra 61's into a twin configuration; O&R industrial, and belted glo engines. We had success with Roper engines purchased from Horner Sales, which were converted to glo. The we heard about Ron and his Quadra. George Privateer and I each purchased a Quadra from Ron. It was the answer to our prayers, so I immediately became a Quadra dealer - the first in the USA - getting my engines from Ron. Sales were so good that Quadra decided to set up an aero division, and the guy that became sales manager - I have forgotten his name. He was replaced by Bob Cooper, and Bob lasted I would guess another two years when he decided to move on. They asked me to be the US Quadra representative, but I had a full time engineering job, and couldn't accept. That's when Dario Brisighella and Dick Bennett got on board, and I am not sure of the order. I then had to purchase my engines from both parties, since there were no more direct sales from the Canadian factory. This is about the time that I believe Klaus Nowak entered the picture.
He may have always been with Quadra, but I didn't meet him until hundreds of Quadra 35's had been sold. He may have been Bob Coopers replacement, and it was Klaus that developed the Q50 engine for model use. Klaus also sold a tuned pipe for the Q35 that gave it the power of a 50, and I believe that is what got him his job at Quadra.

When Quadra had manufacturing problems with getting their cylinders chrome plated, I tried to get VanderHorst Corp. in the US to do the job, but there wasn't enough money in it for them to want the business. About that time, Quadra went out of business and Klaus Nowak took over the line of model engines. I lost track of them after I sold my business.

If anybody gets credit for starting the Giant Scale movement, it has to be the STARS club in Olean, NY. We had the Bristols flying at Rhinebeck on Ropers a full year before the Q35 appeared. Just for fun - here is one of my first Quadra sales bulletins:
