207-900T which is, you guessed it, the twin engine version. It has two IO 470s up front, one behind the other. The rear one drives by 2 gears to a shaft over the top of both engines, which turns a left handed prop (the gears reverse direction of rotation), and the forward engine uses a hy-vo chain to drive a hollow shaft concentric with the other. This has a right handed prop just behind the LH one, so you end up with contra-rotating props and no P-factor to worry about. The beauty of it is, you can shut down the front engine (NB. it drives the rear prop!) in the cruise, feather the prop, and get really good fuel burn figures. To re-start is simplicity itself, you just un-feather the rear prop and the wash from the front one spins the engine up! This is known to old -900T drivers as "getting a blow job!"
Sailing, I used to fly a 207-900T in Western Zambia. The rear engine was a bit unreliable (cooling issues), so single engine Takeoffs were common practice. I think the seat rails were modified in this one, so if the pilot seat flies back, it only goes back so far as the 3rd row, instead of the tailcone. Our engineers also installed a switch that was activated when the pilot seat hit the stops back in the 3rd row, so the autopilot (single axis, pitch only) was automaticly engaged in ALT HOLD mode.
Many "blow jobs" were done in this aircraft
