This has been scaled down exactly from the .40 size version once kitted by Direct Connections. Span is 36" with a weight of 18+ ounces. Tried to keep it down to 14 or less but couldn't manage it. The Norvel .061 just wouldn't cut it, at least not if you want to duplicate the original. The .074 came to the rescue. It sports a throttle adapted from the CS .049. This was done before I discovered that the .074 throttles extremely well with its own stock throttle. No adjustable airbleed required. This engine is going to go down in history as one of the best ever, in all respects. Extremely well made, very high power to weight, bolt on muffler and throttling that is among the best.
The long pipe is a piece of Flyquiet tubing added to the end of an adapter made for the stock muffler. A baffle is installed and this is adjusted till you hit a sweet spot. You get a tuning effect that adds 500 or so rpm. Best of both worlds, quiet, more power and all the goop blown back and away. The tail wheel gets most of the soaking but that's not bad.
Anything the big one will do, this one will and then some. Knife edge loops (sloppy) have been done along with all the usual stuff. Slows to a crawl for right at your feet landings.
