The YS110s are rarely available. But right now they are available at Cental Hobbies. They sell for about $325.

The Saito 100 is not enough engine for the Showtime. At least I don't think so. The Saito 125 or 150 would be excellent choices as well as the YS110. The YS adds the advantage of a pump to allow the tank on the CG. I also think the YS is a better engine in the higher locations because of the supercharging effect.

Any of the above engine except the Saito 100 would be excellent choices for the Showtime. It's gonna weigh just under nine pounds. Gave or take depending on which engine.

Thanks
