I didn't buy the YS because it was $325 bucks when all of the competitive engines like it were a hundred dollars or more less. My Rossi's were $200 dollars with pipe and header. I know two people using the YS and it's a powerhouse. They don't post, they are usually out practicing and winning contests. It's a good engine to be sure.
Rodders if you really want an Arrow, Don at RCAiir will make yours and ship it in 10 days or less. Why mess around with vaporware when hundreds of complete kits have been sold since 2009 by RCAiir while other various "kitters" announce big but produce little? Don is finishing a gorgeous vacu-form machine to make large canopies, I saw it yesterday and can't wait to get my Miss Beetle with it's clear canopy.
