I know this bug's been reported and possibly fixed already but it's still kinda hilarious.
For those who don't know, the Jeff has been suffering from low drag especially at low altitude.
About to land, a few miles from the airfield, I put out my airbrakes, put down my landing gear and put my throttle to idle. Note I'm still a couple miles from the runway and completely idle. Without touching the throttle again, I maneuvered the Jeff into a decent glide slope and came in for landing around 160kts. After touchdown I put it into aerobraking till 2/3 the runway length at kobuleti. It still wouldn't slow down. I pulled the nose up even more and tail struck. I dragged my tail across the remaining runway, and it wasn't until I hit the fence that the plane tumbled to a standstill. My throttle has been idle for a good two three minutes now. The Jeff gives no oofs about no airbrakes or drag.
Only the wheel brakes and dragchute can slow it down apparantly.
