I was eyeing up some of the R.V. kits in one of my local shops a while back.
It definitely looks like a nice kit, but every pitot boom in every kit I looked in was broken in exactly the same spot because of how the sprues had been packed in their bag.
Unless they've changed their packing style to better protect that part, I'd be budgeting for an aftermarket brass pitot when buying one of these kits.
