Being as you are talking about flightboxes. My father and I went to a Scale-fly and, being as we arrived late, we had to park a long way from the start up box. I had my B-25 and carrying it and the flightbox that far gave me a wild idea. Remote controlled flightbox! With a retractable dog-leash of course to tow the plane. I had a few old torn up Power wheels at the house that my kids had pretty much destroyed so I went to work. The end result works pretty good. Powered by 2 5000 Mah 3 cell lipo batteries that used to run my Rustler, They run the power panel too, it will pull a 12 ft telemaster and has no problem toteing a 40-60 sized trainer on top.
