  1. Had a E36 M3 which is probably the car I have loved the most.
  2. When you burn more oil per hour than a Mooney burns gas.....
  3. 1971 MGB, Parkers Porsche is cheaper and faster.
  4. If I am not rebuilding one engine, I am rebuilding the other....
  5. It is actually a pretty easy pathway to certifying the engine. The only requirement is money.
  6. It is important I think to make the distinction between performing a maneuver and ending up in an unusual attitude. A spin as a demonstrated maneuver is PARE and is a non event for the most part. An inadvertent spin is probably not going going to be recognized prior to proceeding to a spiral or impacting the ground (base to final turn). Obvious exception is when demonstrating stalls where you can anticipate it which is why it is a required training for CFI’s and the only acrobatic maneuver exempted from chute requirements. Just like stall training it is to understand and avoid primarily The odds of actual recovery from an inadvertent spin are not going to be very good in a high performance aircraft.
  7. You are referring to a graveyard spiral. A spiral is defined in AC 61-67C reasonably well. "Many airplanes will enter a spin but the spin will become more vertical and degenerate into a spiral". In Bill Kershner's Student Pilot Flight manual he explains the maneuver to the left in part "Once the spin is established, you can maintain it as long you like with full up-elevator and full left rudder. Relaxing the back pressure will result in some airplanes going from the spin into a spiral". There is a video of one of his trained CFI's doing a lot of rotations in a C150 from 17500 straight on down, air speed is consistent, rotation is consistent, it is a text book maneuver of a spin. There is a fair amount of stuff out there from Bill Wheat and Bob Kromer on spinning a Mooney. My experience has been if you lose the spin in a Mooney, what happens next happens very fast. Best not to play around with. In short a spin is an aerobatic maneuver which is benign in aerobatic airplanes, spirals kill people.
  8. Vne won’t be exceeded in a spin. A spin is an aerobatic maneuver where you rotate around at slightly over stall speed. A spiral is what happens when you release back pressure in a spin. It comes with ever increasing air speed. Spinning a Mooney is survivable as evidenced by several here (it is again a maneuver). You take a very slick airframe though and the ever increasing speed of a spiral you can certainly have some problems trying to break out or bending things due to the G’s of breaking out well beyond Vne. My experience is most people can’t hold a spin which is the problem (failure to adequately perform the maneuver), not the maneuver itself. Certainly an inadvertent spin is almost always going to lead to a spiral.
  9. This varies by FSDO. Shebly a few years back had an LOA to do 6+ a day, there was some drama around that. Most are 2 initials and 1 add on per day (e.g. add a multi commercial to single commercial).
  10. I would suspect if you did 120 on the climb your temperature issue would go away and your rate of climb would be very close to the same.
  11. Not Intercooled, manual wastegate. The biggest risk on the wastegate is failing to remove it on descent, otherwise fairly idiot proof.
  12. https://mooneyspace.com/forum/16-vendor-forum/
  13. KCMX DNA, your snowfall is weak but your airplane is hot.
  14. Just be like everyone else and use the biggest sheet metal screws you can find along with an impact drill :-)
