Here's a photo that Rich Verano sent me a few weeks ago. He was initially disappointed in the engine's performance; so
he called YS and they sent him another engine along with the header and pipe set-up they were using and getting more than
1,200 rpm better than Rich was with the same APC 11x9 prop (YS was getting about 14,000 using 15% nitro fuel).
The package from YS arrived this week and Rich attached their header/pipe set-up to his (the original prototype engine)
and got similar rpms. Then he mounted it in his Escape (built by Joe Bridi himself) which he flew last year at Chip's CPA contest
with a rebuilt YS longstroke. The performance was significantly improved. He feels the engine is a real powerhouse and a definite
winner. He believes the engine should be available very soon (by YS standards - so hopefully by March).
By the way, the factory pipe setting was 1.5" shorter than the one rich originally used to test the engine. More testing with different
pipes, props, lengths should happen soon.
