That horn is GREAT!!! Is the echo recorded or real? Are you running those nozzle things, sure steers nice. Very inspiring model! I'm still stuck on the sternwheeler thing and a nearby LHS has a Myrtle Corey in stock. Think I'll give it a try. It looks to be large enough for all the steam and radio gear if I modify the deck to keep everything low. Finding(and paying for) a good boiler will be the hard part I quess.In what way is a towboat easier to build?
