Wow Philip ... what an interesting and relatively old company, and might I add, fine looking engine line. Never heard of them myself, but then they are an ocean away and I was dealing with a rather parochial, standard American market back in those days. Thanks for the link.
I can only guess which brand of my engines finds your favor (Fox perhaps, yes?) ... but I must say for simplicity and reliability they were our go to engines, and I have a true fondness and respect for them!
Yes i must admit i was also surprised to learn more about Progress Aero Works and i'm pleased they are still making engines here in the UK. I must admit the more i keep looking at their website the more i want to replace the little engine i sold on!!
Hope you may add a P.A.W to your collection in the future, they do require a different fuel mix though and can be a bit fiddly to get going but have the advantage of not needing a power source or glow plugs to run.
Yup it was the Fox brand!
, i also heard good reviews about them and i wasn't sure if they were still in business?
