I had some time this weekend so I went about challenging myself to make a scratch build pusher with a "T" tail! During some engine runs I noticed the vertical stabiliser was getting moved around quite a bit by the turbulence from prop. I fixed this problem with a couple BBQ skewers for bracing. I was shocked at how much authority the elevator had considering it's a relatively small surface (I had to dial the rates back to around 35% to make it smooth). None the less it was an great proof of concept.
