Can/will this be added?
Sometimes one wants to build the cheapest (in material and time) vehicle possible that is not meant to take part in crashes. I consider handles to be cheap (just one pipe) and very light-weight (1kg). (Wooden frames are also cheap, but not as light weight at 8kg, Quite important if one plans to move by [G]rabbing ).
I can already construct all-handles vehicles by first starting construction with one of the other frames, adding handles to it and then removing the starting frame.
What is the difference between wooden handle and wooden frame? Durability and weight are both the same.
