For the turbo models:
1. Bitch to re-start when hot
2. Three minute cooldown
3. Needs the turbo just to fly - 29" was the minimum power required in the cruise, so lose the turbo and down you go.
4. Horrible things
5. See 4.
6. Ditto.
7. Engine dipstick seemed like 6 feet long with three twists and turns to get to the oil, easy to bend it when in a rush
8. Horrible things....
