If it is balanced properly you do not need any elevator trim, except with the flaps. The elevator is trimmed when a straight edge across the TOP surface of the elevator is flush. A bit of down thrust on the turbine as well, about 3-5 degrees. The usually accepted CG is about 13 in. from the leading edge at the fuse.

Thank you John,
So I have to make the TOP of the elevator parallel to the flat bottom.
(Not have the elevator bottom lined up with the section underside.)
That's good.
That agrees pretty much with the photos, but is more precise.

It doesn't sound like you got it.
Re-read John's post. Forget about the bottom. Lay a straight edge on TOP of the stab, along the flat portion towards the rear. Now bring up the elevator until it just touches the strait edge.

The methodology is to put a straight edge on top of the horizontal stabilizer and make the elevator flush to that straight edge. This makes it look a little strange from the bottom, but it flies well this way. I can remember reading a post here some while back of a builder that decided the stab should not be built that way and spent quite a bit of time rebuilding the plane to this new configuration ( he flipped the stab over and installed it upside down). I never heard how his flew after all that work. Mine flies very well in this stock setup.
I have a P-60 for power, which makes it scoot pretty well. I don't think it would do well with a smaller turbine.

Here is the Tornado Jet?
Is it not produced anymore?

Been a long time since last post....

Ok picked up a Tornado a few months ago...on the outside it looked good but on the inside it needs a lot of LOVE!!!! Gap/Expanding Foam…! Not sure why they added foam. There is wood bracing in the fiberglass. To me a total hack job… removed so much weight from this jet. They converted it over to a large edf but totally hacked it in my opinion I removed so much wood and epoxy. Still loads of epoxy he just poured in 🙁. In addition they had 3lbs of lead weight on the tail…

How do I know which version I have. I am looking for landing gear and trying to find a used pair for the proper version. Thanks.

I do believe that all the Falcon 120s and the Tornado are the same, no version difference. I still have one of the originals and it is identical to the Tornado.
The gear I have is 130mm from the axel to the center of the retract pivot and I use a 2" wheel. I think you can get as big as 2 1/2" wheels in the well. I didn't measure the nose strut.

John thanks for the info!!!

Don't be too hard on the previous owner of that Tornado, they where put together with what seemed at the time like flour paste, on my version I was able to push out all the formers with a gentle tug, it was then put back together (with mods) with Hysol, lasted well until a Futura went through it.

Ok I will try not too . Just finished removing 3.5 oz of eboxy from the section where the nose wheel enters the fuselage . There is plenty more to remove probably about another 6 oz. Going to clean it up some more and then add a thinner layer of epoxy to that same area.
