RE: Jet ground support
The pictures below show my solution, a $49.95 garden cart from K-mart. I added the white top tray and the small black wheels. It holds a 5 gal. kero can, fire extinguisher, transmitter, flight box, start up exhaust tube, everything I need to fly the Boomerang.
It is light enough unloaded I can easily lift it to the ground from my Van. by myself.
