Great, so you guys fly with the YS 1.10 in your 60? and you like it allot, can you pull out of a hover at a pretty good pace? And can the YS 1.10 fit on the stock engine mount, or does this involve changing the blind nut positions on the firewall to fit a bigger engine mount? Also just to make sure that the YS 1.10 engine we are talking about, is the new YS FZ-110 that took place of the 91 correct? also whats the street price around this engine, i saw on one sight it was $323.87 does that sound about right? thanks
