I ordered a Nitromodels Katana 50cc on
www.nitroplanes.com and (according to UPS tracking) it's "out for delivery". I'll start putting it together tonight and will post the adventure here, for anyone who cares. :-)
In times like these, a cheap quarter scale plane sounds like a good idea to me. I'll put in a 50cc CRRC engine in it (also cheap) and some 140oz at 4.8V Hitec servos.
Watch this thread for updates later today or tomorrow.
