-Wow, very nice! With that many motors, you could afford to lose one and still get it back home safely! I saw a picture of a "Spruce Goose" model once that had .049 motors; how he got all of them running at the same time was beyond me! Be bold, have fun!
-The Tower 40 trainer makes a good platform for breaking in motors and learning about multi engine planes without all the time and $$$ investment. If you dork it during a flight test, you patch it up and try it again. It's not a plane that you get really attached to. BTW, it was a really poor handling plane with 7 motors, but the pilot did bring it back in one piece!
