RE: Jet ground support
I made up a flight box to keep the size & weight to a liftable figure. If you make up a trolley to cover every possible situation it could end up being so big & heavy it will be a PIA to use.
All going well I only need enough to fuel & charge my jet & fill the retracts so that''s all I put in my flight box. I only use a stand to assemble/dis-assemble my jet so I kept it seperate. Likewise with tools, only need them when things go wrong so I get them when I need them. My fire extinguisher is a big one so I did make up a seperate wheeled stand for it. - John.
