RE: Oddball engine
Well when that engine was built there weren't very many (if any) giant scale engines.....so this was one of the first examples of trying to swing a bigger prop at all costs...at that time people were trying to gang two 60's together to swing the big props...(aka hannos dalotel). I have only seen one run and it pretty much knashed along with all the gear noise. The bigger engines (and the gas engines) killed the idea (along with the associated problems of a gearbox).
