This is a long video but if you have ever built a complicated semi scale CL stunt model you will appreciate how they and you both used very similar costruction. I had built hundreds of models in my 72 years but until I built the Rabe 1968 Bearcat most had been conventional CL stunt model construction. Rabe's first bearcat was a normal box body with hollowed blocks. That is the method used in the 1960's. I used the newer method of formers with a thin outside covering hoping to build a 55-60 ounce plane. I had to engineer everthing as I went along and everthing was very light but I made many mistakes and I covered them up and went overboard in building it strong and it came out heavy. It is amazing how well it flies at 70 ounces.
This Learjet Video even shows how they put on the finish and then sand most of it away to get that front row finish. Front row in the real world of commercial hand built aircraft. Yes all aircraft are handbuilt but not hands on to this level of craft-manship. They show the man buying the plane and he seems to be a very down to earth guy considering he is paying 14 million for this plane.

Exelent manufacturing enviroment, reminds me of what I do all day except I have F/A-18's and F16's, and the interior isn't as nice as the Lear 60. ! wish I had 14 million to blow on one of those !!!

Thanks for sharing Ed, that was a good progam.

I've done acceptance checks on brand new Boeings Airliners. They are every bit as nice as this....when they are factory new.

Great video, can't wait to show it to my class. But!...trying not to stir things up; I couldn't help thinking the whole time I was watching...The new owner is the "upper two percent" that our current administration is trying to destroy, along with all that I've dedicated the majority of my life to. IMHO

Most of that "upper two percent" are the most generous people in our country. They just don't run around "tootin their horns."

Watched the video thinking wouldn't it be great to have that kind of cash. All the contests I could get to, especially with that plane. But, then the thought hit me, I would probably not be playing with model planes anymore or to even start with.

I am not a subject of the US, but sometimes I do wonder why people can go from building planes to knocking their pet political dislikes. Can't we just enjoy model planes (and full size ones too) without dragging in political slants. There are plenty of other forums where you can hate democrats or republicans to your hearts content. Please use them when you feel a pet hate coming on.

I'm with you !

EddyR · « **Reply #12 on:** December 08, 2012, 01:06:08 PM »

Andrew I agree with you. I thought the video was neat as I could relate to it. They put the plane together very much like a model plane. Each one is set up the way the buyer wants it. Lear is small potatoes compared to commercial jet production. I had three hop ride in a old but total rebuild Lear two years ago and it was a fun flight and it was free. It is owned by the DOD and has a large eagle painted on the rudder

Hello Ed,
Forgive me, I really enjoyed the video. Thanks for posting it, glad you had a fun flight on one!

Regards,

Andrew.

Nice video. Couldn't help but to be proud because me and my crew designed and installed the first L-60 XR avionics. The dispalys, controls, standby intruements, etc were all designed and installed by my crew. This was about 6 years ago. Then Learjet took the data and rolled into their production line.

Our avionics can be seen at:

Sorry about my little interjection of a "so called political comment," but I believe a couple of you missed the point of the comment. First; the truth in the comment and secondly the truth in that it all may disappear. Think hard about what's coming down the pike...modelling may soon be the only high dollar aviation out there. I'm done.

My rebuttal doesn't belong on model plane forum either. - SK

What do those lower wings aft the engines do? Do they move like flaps and elevators? I have seen them on fighter planes as well.

I watched the whole video. Truly amazing!

Cool video. Check out those balance tabs at 31:30.

Thay are called strakes. Thay are fixed and they are used for stability.

I remember seeing them on some fighter planes a few years back. I have always wondered what those would do on a stunt plane???

If you plan to fly your existing stunt plane at 50,000 feet, I reckon they'd improve the damping.

Hmmmm, but then my line slider is giong to have to be really long to handle all that line rake on 50,000' cables. But I could get a little better setting on 50,000' solids.

Now where I am going to find 100,000' circle to fly on??

Gene O'Keefe · « **Reply #25 on:** December 10, 2012, 07:36:37 AM »

The strakes help prevent a stall that the earlier Learjets had a concern with.

The TO's / manuals I read all the time call them ventrical fins (USAF) F-16's that is.......

The "strakes" (Ventral fins) on the V-tail Bonanzas (STC) we take care of, are suppose to dampen their notorious, so called "Dutch Roll." I've flown both, some with and without. Didn't notice much difference...matter of fact...didn't notice much of anything.
