Over 50 years ago i was at a friends house and saw a glimpse of that 0-45-1 model in the back of his garage. The image of that opposed twin engine has haunted me for years. I'm a two stroke fanatic and always wondered what one sounded like running. Now I know. Thanks.
@tomfey60203 жыл бұрын
You are welcome. Running them is the great fun for me. The 0-45-1 is cantankerous to start because the slow pull-over tends to dribbles fuel, not really really atomize it. The 0-45-1 has a much deeper bellow than the smaller drone engines.

Loved the engines but specially the second, contrarotating one. Great video, mate.
@tomfey602015 күн бұрын
Thanks for your comments. The engine with the contra-props is a Righter 2-GS-17 built in June of 1943. More info about the engines here: www.enginehistory.org/Piston/WW2Drone/WW2Drone1.shtml

Where do you find parts?
@tomfey6020 Жыл бұрын
Parts are typically acquired from a second engine or trades among fellow collectors. The 36 x32 propellers and Champion R-1 spark plugs for the 0-45-1 come across online resellers a couple times a year. Museums typically have drone engines stored in back, often willing to deal. Carburetors, propeller hubs & flanges, and mounting eyebolts are extremely hard to come by. There are no "new" parts.

@@russcole5685 , thanks. The engine is relatively low compression (4 to 1) so not too hard to throw over. The gearbox and props add a fair amount of inertia so it doesn't accelerate dangerously fast. Fingers flat on the fore blade, not wrapped around it, is essential. I finally have the engine dialed in now so that it takes 4 cold priming pulls, then typically starts on the third hot pull. Per the manual, piston Top Dead Center is when the fore blade is at 10 o'clock as I face the engine from the front. A new engine should get to 3,800 rpm before launch. My engine is 77 years old, gets to 3,500 rpm or so. The propellers were patterned off the originals and made in 2013. I left them 1/8th in thicker for safety. The following video was the second time I started it, dripping carb and all, so be patient: kzbin.info/www/bejne/fqPYqoeNbMiSatE

Starving for gas
@tomfey60203 жыл бұрын
Perhaps, but the larger engine was actually flooded for some of the time. Because they only get one rotation from the hand starting, airflow through the carburetor is slow, causing fuel to dribble as liquid into the engine, not atomize. The use of the atomizer to the carb while throwing the prop over was an attempt to get a vaporized mixture into the crankcase and cylinders instead of wet fuel. An improved atomizer has remedied this problem.
