Sculpted wing tips for M20J

[Kevin Gill]

Will the sculpted wing tips from an 83 M20J fit on my 77 M20J without lots of modifications? Counterweights the same?

Im a newbie.   Thanks

No, to do that you'll need to re-skin the outer wing section to provide the flange for the wingtips to attach.  The later skin is a little longer, and protrudes outboard past the end of your wing.  You'll also need to change the aileron end rib and counterweight.  I had all this done while getting hail damage repaired and I'm very happy with the upgrade.

If you're willing to go that far, then you should step up to something modern like I did:  Crystal Conforma for Mooney - AveoEngineering

As @KSMooniac pointed out, No you can't without a lot of modification of the ailerons, counterweights and outer wing skin.  The construction of the ailerons changed after serial number 24-1037.  Your counterweights (the early J's) are large, blunt and exposed on the front when fully deflected - the later models are streamlined the weight and concealed it in the wingtip.  Also as pointed out the last section of skin on the wing is a little longer to overlap the Factory wing tip.

• Since you are new to Mooney, do you know that there are Illustrated Parts Catalog (IPC) and Service Manuals online in the Downloads section? (links below)
• The Factory wing tips are flush mounted and the aileron counterweights are fully enclosed.
  • There are after-market Mooney wing tips for early J's - LASAR used to sell them - which overlap the wing skin and still allow the counterweight to be exposed when fully deflected.
    • @Jesse20 had a set for sale earlier this year but they may have sold.  Wing tips $3000 OBO - Vintage Mooneys (pre-J models) - Mooneyspace.com - A community for Mooney aircraft owners and enthusiasts

@1980Mooney, you grabbed a pic of my old paint and old wingtip somehow!  (the maroon tip with the 201 painted on)

My plane has changed a lot since then!
