MtnMann Posted September 18, 2022 Report Share Posted September 18, 2022 New in box. I ordered them 14 years ago for a plane that was new to me at the time but found out that my M20F had a C wing! So I never installed them. It’s all from LASAR SOLD…. Quote Link to comment Share on other sites More sharing options...
Jpravi8tor Posted September 19, 2022 Report Share Posted September 19, 2022 Soooo what does it fit? will it work on my 1975 M20F or is that a C wing as well? Quote Link to comment Share on other sites More sharing options...
MtnMann Posted September 20, 2022 Author Report Share Posted September 20, 2022 It is for the M20F so it should fit your 1975. I only say ‘should’ in case I’m unaware of any specific difference in your year. You could easily verify by calling Lasar. I bought it for a ‘67 M20F.

TomM20F Posted September 25, 2022 Report Share Posted September 25, 2022 Can you confirm the attaching hardware and STC paperwork are in the box. I think to install it is mounted with cherry max rivets. Quote Link to comment Share on other sites More sharing options...
MtnMann Posted September 26, 2022 Author Report Share Posted September 26, 2022 I just looked in the box. It is both the flap gap AND aileron seal kits from LASAR. There is STC paperwork and rivets. I ordered it in 2008. 1 Quote Link to comment Share on other sites More sharing options...

Bryan G Posted September 27, 2022 Report Share Posted September 27, 2022 I have a 1967 M20F, how did you find out you have a C wing? If I can verify it would fit my Mooney…where do you live? Quote Link to comment Share on other sites More sharing options...

If you want to see all the different parts between a C wing and an f wing… the parts manual has a nice way of pointing out the small differences… PP thoughts only, not a mechanic… Best regards, -a- Quote Link to comment Share on other sites More sharing options...
MtnMann Posted September 27, 2022 Author Report Share Posted September 27, 2022 The C wing has less fuel capacity - for one. But also, only the ‘67 F wings have a twist towards the tip. That twist requires slightly different rigging of the elevator which means a bellcrank for the elevator linkage has different dimensions than the one used on a straight wing. That’s what ultimately made me realize the difference. My ‘67 F, when rigged by the book, would fly straight and level with the elevator slightly pitched. I had to rig it out of spec to get it to fly true. In order to do that, one of the heim joints on the bellcrank was extended just beyond the safety hole on the threads - which I knew meant something wasn’t right. That’s when the lightbulb went on and I looked up the part number on the bellcrank and sure enough, ‘67 has a different part number from all the other straight wing F’s. The twisted wing was not a good idea. It slowed the airframe down and they did away with that idea the next year. My ‘67 F with a C (straight) wing was probably the fastest airframe of all ‘67 F’s! This wing change was done after a gear up landing totaled the original wing. Logbook entry was vague and didn’t mention that the wing was not an F model. No part number was given. Previous owner passed so when I bought it, the mystery began. It took a few years to figure it all out. 1 Quote Link to comment Share on other sites More sharing options...
