RE: TBM DV8R anyone have one or about too?
I would assume the reason for uptrim is the difference in the incendence between the horizontal stab and the main wing. If I recall, it's like 3 or 4 deg. Not sure about that.
Flew my DV8R today with the longer struts. She lands better as you can hold a little more flair now and not worry too much about the tail hitting.

Keith,
I have experimented with the up thrust on the P-120SX and have made 4 thrust changes in the turbine, you are again right on in your comment. I have taken all the thrust trim out.
I forgot to ask you how much ailreon Diff are you happy with. 8% 10% ??

RE: TBM DV8R anyone have one or about too?
The reason I shim the BACK of turbine was to take away the DOWN Force at full Throttle. I have built 6 of these and they have ALL been the same! The first 3 I had, Had a Jet Central Eagle with 30 pounds of thurst. At Full throttle it would VIOLENTLY go straigt to the ground!! What it was do was tring to Push the Tail over the nose. So with the Shims on the rear it change the thurst angle. This WORKED GREAT FOR ALL SPEEDS!!! It still required a couple notches of up trim, But the down was GONE!!! Another thing I have noticed is that A LOT of people are NOT doing the CG at what is said!!! I have over 400 flights on these! To me There is no need for crow.....UNLESS you FORCE it to land. This plane will land at about 18 to 20mph. Any faster... Bounce...Bounce..etc......
I have received some retracts from TBM, Serria, and Now from Germany. Will be testing. I will also post some pictures.

I would also agree with you on the CG. I found the recommendation in the manual to be perfect. I would reemphasize to everyone to follow the manual for both CG and throws.

This is what I am hearing!!! The ones I had/Have have a little down in the engine rails. I had asked them to Leave the engine rails off, But that didn't happen. They did most of the other changes I requested. Maybe they changed the angle of the engine rails on some. Don't know that answer.....
To All.... I have asked to get a price on just the wing, fuse, controls, etc. Should be getting a answer this week sometime.

I just got done building mine, I was curous if the 1/2" on the ailerons on high rates were enough? did you guys leave em that way + / - ?
Also did you guys use the specs from the manual when setting up the elevator down to flap mix? If so are the perfect when the flaps are fully deployed for landing? Thanks In advance.

RE: TBM DV8R anyone have one or about too?
I had to land on the nose gear and one main landing causing a lot of wear and tear on the bottom of the stab and elevator tip. So to eliminate this problem in the future should I have another issue ( found the brake line had rotated and jammed the main gear) I added BVM wing tip skids. There was no damage to the wing tip because the stab held the wing off the ground.

RE: TBM DV8R anyone have one or about too?
David, a few suggestions if you don't mind. I would make some longer skid plates on put them on the rear part of the fuse where the horizontal stab plugs into the fuse. The reason being is that if you were to hit again, you want all the energy to be directed into the rear fuse and not your horizontal stab. A few have lost dv8r's due to hitting the stabs and then taking off only to find that it had cracked or weakend the stab and failed in flight. Just an observation.
Second, I would trim your control horn screw. If you sit your dv8r on it's mains, and add a bit of down elevator and push the tail down, you will see it's going to hit that screw. I did not trim mine and I had mine hit and it stripped out two metal geared servos.
Just some observations, hope you don't mind me saying so.

RE: TBM DV8R anyone have one or about too?
Test flew my TBM DV8R today. Flew very well with very little trimming required. A slight bit of up evevator was required. Will also have to add more elevator down trim for the recommended flap settings. Power is a P-120SE, changed gear on mains to Robarts with 4" BVM wheels and brakes and used the Robarts struts from a PCM crashed orignal giving a very high stance and good clearance for the stab when flaired for landing. The nose gear is the TBM gear. Also moved the rear of the stab mounts up so that the elvevators are level with the rear of the fues. Landing was accomplished with no crow and was a non event except the nose wheel did not come down. Appears to be some binding with the steering arms on the retract and the mounting plate. Minor damage on the nose section as a result. Overall, pleased with the flying chacteristics. They appear to be very similar to my orignal PCM DV8R.

Can you post a picture of the stab mount, moved the rear of the stab mounts up so that the elvevators are level with the rear of the fues.
Thanks
