  1. So a summation view is that people climb out based on what they were taught and sometimes add sound to that and pull back the prop RPMs. What I was hoping to hear was. a 74 inch prop at 2700 RPM is not at peak efficiency. It really should be spinning at 2800 or 2850 depending on temperature to be at peak efficiency. Lycoming says the engine is good to 2900 (would not 2900 be a more accurate WOT) It is only the Type data sheet that limits down to 2700. Even at 3200RPM the tips of the 74 inch prop are not supersonic. So why does the type data sheet say 2700?
  2. I don't think welding cast alum would work. Now someone with a lathe and milling machine could knock that out in no time. I can't remember if I saw that in a Cleavland wheel catalog or LASAR website. Took a quick scan through the wheel catalog and did not see it. If the wheel would support it you could go to the later hub caps that are held on with 3 screws to the tire rim.
  3. Which is kind of like a factory re-manufactured. A bunch of used parts checked if they are within tolerance and put together. But since it is the Lycoming they get got 0 time the engine.
  4. If the cam is OK then I would go with a new number 3 cylinder. You can get a lycoming Cylinder from Plane power for about $2K. flush all the oil related items if there was contamination which there probably is. our engines are known for not getting enough oil to lubricate the valves. It cokes up, they stick, the engine eats them. This is a good read. http://egaa.home.mindspring.com/engine1.htm They need to check all the other cylinders exhaust valves wobble test and possibly ream them.
  5. Mine spanned 4 1/2 days. Pulling panels is a good days worth of work. To inspect everything on the checklist would take a day. Replacing panels and recowling is a day. This was the first time the IA had seen the plane so I spent an evening researching the AD list. Then we spent several hours reviewing it. I would say the IA spent a half day on documentation because it was new to him. Would go faster next time. Extras were replace 1 flexible brake line and bleed. Replace the front main seal. Probably added a day of time.
  6. I always like the idea of steel balls as it would mimic the english wheel process. Hand working metal fascinates me
  7. Seems like liquid nitrogen like they use to burn off the pre cancers would be a lot more pin point application. Shrinking metal would be the theory
  8. I would go with this if you want to be sure...
  9. It was the car egress hammer that my mom gave to me with the seat belt cutter thingy like you suggested. I used the pointy side. Did you try it from inside the plane? I think the slight bend/tension that is in the window would help to break it, but hitting it from the inside would be less effective. Also a bigger piece would need more force. It would also follow that I would expect the crash to help break some of the windows. Not an engineer, just a business major that likes to break things
  10. There was some broken cloud cover. Nearest airport button. Circle to land Tell ATC "unable" a bunch of times and tell them to clear a path.
  11. lost a mag. Lost #3 cylinder.
  12. yay flaps. There is a pin on the outboard side on each seat back. I found to have them unlatched and slightly forward makes getting to the pin a bit easier. I am tall enough I could reach in the baggage compartment and pull them out. Also had the passenger seat out to put them back in.Make sure to include the seat belt when reinstalling. Also flashlight helps.
  13. I am listing the hammer as probable. I took a small piece of 1/4 plexiglass The first three strikes only put three indention. This was hand held with one edge on concrete. The fourth hit was braced on both edges. The fifth hit was really good swing and it broke. I am still not sure on a larger more flexible piece it would work. And I am popping the door latch and shoving something to hold it open.
  14. The 75 F has removable rear seat backs. They are pretty easy to get out. Getting them back in the first time took about an hour..... During the annual I learned to put the seat back in prior to the lower cushion. I find the rear seats quite comfortable even being 6' 9"
  15. I am using my legs if needed to get past something door/window. Tapping on Plexiglas with a tiny hammer does not seem like a plan.
  16. http://www.lycoming.com/Portals/0/techpublications/serviceinstructions/SI%201427C%20%2812-29-2010%29/Lycoming%20Reciprocating%20engine%20Break-In%20and%20Oil%20Consumption.pdf it does not past well so you need to read it. I created a little spreadsheet checklist to carry with me
  17. I say close the cowl flap. You are trying to eliminate oxygen to a fire. The airspeed is to push the flame away from the source so you then just have the source with no flame. I kind of skeered myself the other day by thinking I would play strafing run at something. The plane will speed up very very fast when pushed forward. My transition pilot (former F=18 pliot) was saying that a wing over in a Mooney is not that great of an idea because of how fast the plane speeds up. I would think flaps out, gear out and a spiral would have you on the ground in no time. also in a spiral the flames would be pushed out to the side instead of into the cabin.(I think)
  18. open the picture in Paint. Click on Resize. put 25 in the horizontal or vertical box and save it
  19. This is one of the airworthy tubes that came on my plane. I could probably figure out the date codes on the tires, but just happy to have new shoes on the plane. Still was holding air.... not sure how..
  20. Trick question. The plane is already out of annual so the ADs don't matter at that point.
  21. According to my father who used to run a fleet of 200 mixer trucks... A Schrader valve (car, truck and airplane) type valve was not designed to hold air and the cap is supposed to do that function. Not sure, but I would not have a valve sticking beyond the tire width. There are some shiny places on my oily wheel well. You could use a Greely Hole punch to put a hole in a wheel cover. I need to do that and put my covers back on......
  22. let's try best for Take off
  23. Cutting off nose to spite face.... How does all the money get there to be spent? Best I heard of this was complaints by the locals about an Army base. One day the base commander ordered the payroll to be paid in $2.00 bills. Locals stopped complaining
  24. Basics Mooney 20F Type data sheet says 2700 RPM http://www.67m20e.com/Mooney TCDS 2A3 Rev 52 dtd 9DEC10.pdf 74" Prop says 2800 is still keeping the tips below supersonic and 2800 is actually getting the prop up to the maximum performance levels http://www.warpdriveprops.com/propspd2.html Lycoming says for an HIO360 - Max rpm is 2900 http://www.lycoming.com/Portals/0/techpublications/servicebulletins/SB 369C (04-18-2012)/Engine Inspection after Overspeed.pdf So what is the best RPM?
  25. Sounds about par for real estate escrow companies. Their one goal in the deal and for which you have the pleasure of paying them is to get all the paperwork together. Usually they forget something
