Front frame is mine and rear frame is from Baddas-cycles.
Mine has the rear part, but isn't that much longer. Front will be about 15 to 20cm longer. I must decide what I do, but probably I keep it as short as possible. Making the sides fold open, so it gets just over 2m wide. This makes that I can sleep in it, but still have a compact size quad.
Left some metal parts out, to safe some weight. It was also not needed. The big opening in the back, will probably hold my electronics, batteries and storage space.
