Slowest M20F ever?

If the aileron weights being streamlined is a 0 indication, then my ailerons are rigged slightly up where the book says they should be 0 to 2 deg down…. The flaps are contacting the wing to body fairing so I’m not sure how much more up I can go with them but I’ll give it a shot. My step is fixed unfortunately and is not removable unless I drill some rivets. Below are some pictures for reference. Will hit up Kleen. Are or were you a Gulfstreamer? I am a COR rep on the large cabins.

Worked with Mr K at GAC for a number of years, I’m now at a rotary wing OEM.    He and I were also hangar neighbors at KSAV before he moved to the air park.  Mr M was my boss for a time.
 

It is interesting, you have old style ailerons.  I don’t recall when they changed, but I thought F models had the new style.  Note that yours are under cambered.  They have higher control force and Were changed when Brittain wing levelers were installed….  You might check the log book and IPC to see if those were swapped out and someone accidentally put the old style on.  That might affect rigging on an F.   Maybe someone with an F can comment.

Interesting. I’ve been through the book and there’s no mention of it. There was a factory repair of the wing in 1972 for some undisclosed reason, but no mentor replacement ailerons.

The newer ailerons have a double tapered trailing edge.  They are near symmetrical.  The old ones have an under camber.  I thought Fs had the new version.  Maybe I’m looking at your picture wrong, do you have more of the ailerons?  Alternately, take a look at some other F pictures….some in the classified area show the newer ailerons.  The old ailerons actually match the flap profile, the new ones have a different shape.  This might lead someone to put on early model ailerons.  Not sure what the impact would be on speed, but might be worth a little.  Certainly lower control lol on the new one.

On the photo in flight it looks like the red light for gear up is not on - it should be always when the gear ist up ( at least on the earlier models -TBC) maybe gear does not go all the way up in flight even if it does on ground on jacks? 

Winner winner chicken dinner! Below is from today’s low pass at speed (my pregnant wife being the camera operating victim. The gear light does go off at higher power settings….because the gear is being sucked down! I rigged them per the book where they are just missing the stops… should they be rigged to where they are against the stops with the bungees under tension? In flight at a lower altitude, I was able to get 145kts with a lot of left rudder in a slip. It also accelerated by 7 knots in a left turn. So I’ll tackle the gear first, then will see about rigging.

What does it do on jack stands?    Does it close on jackstands?

Isn't there also a spring tension measuement that requires a torque wrench a special Mooney tool.  This keeps some linkage over-centered and locked with the correct force, if memory serves.  

Mooney tools KT8442 and KT8444.  I think someone also had a way to do it without the tool, like inserting shims in the spring, then removing them after the adjustment.   

Not an A&P, so I will be hazy on this.

Everything looks good on jacks. In the Maintenance Manual the spring tension (bungee) and tool torque relates to gear down. For gear up, the manual has you referencing the stops and checking the spacing.

OK everybody, go get your low speed pass video and find those missing knots.
