Dear all
Happy Christmas - stay healthy!

I started working on my TUC.
Unfortunately the holes of the elevators which should match with the carbon fiber stab are not in line! Have you made same experiences? I already contacted CARF waiting for a reply.

I tried to upload some fotos. Not possible at the moment. I need at least 10 messages written

Looking for some ideas on how to run the smoke tubes. Any pictures and advice would be helpful.

mautro

This is my approach on a SPT10. Hope this helps.

mautro

Finally I made it - but the way how the holes were made in the factory is bad. I can’t imagine that someone put it together in the factory. I had to drill new holes to fix it.

gbarnes

did you solder the smoke tube to the plate and drilled a hole through the exhaust for the smoke tube and thena bolt/screw hole?
Thanks

mautro

this is a picture of a SPT10 from my friend. I will do it exactly this way.

yes: it is a brass tube. There is a hole in the SPT exhaust. The brass tube is solded on a rectangular brass plate in order to get the tube fixed.

hope this helps?

Hello

In the photos for the SPT10 have you allowed for movement at the turbine mount ? Also how many flights have you had with the SPT10 ?

Thank you

Mark

mautro

dear mark
where Shall the turbine move?

Here are the suggestions from JetCat

Thanks Mark and Dave! I will come back on this topic as soon as I get to the engine mount. Today I finished the tail elevators.

Unilight Austria Clamping System. Nice stuff.

Mate,

Here are a few photo's of how the smoke tubes are done on my CARF Tucano with JetCat SPT5 Turboprop. The coils inside the exhaust stacks really work well as the smoke oils is heated up before it is sprayed into the exhaust which helps greatly to vapourise the oils easily. You will also notice that the spray nozzle is flattened and bent back towards the exit of the exhaust. This was done deliberately to make sure the turbine will not get flooded with oil whilst on idle during a diving manoeuvre.

Cheers,

JanR

Hi folks
how did you solved the linkage to the flap? It doesn’t match. Almost nothing is matching at this model. Crazy

My Feedback: (6)

My assumption would be that your geometry won't work out because you are not using the stock plastic arm JRPA 215, and most of those if not all those servos are not available anymore. In the manual, Dave has measured out from the second hole out from the center of the servo of this particular arm. If you want to keep what you have you will most likely need to shorten it and drill for a new hole. Unless you can get the above arm and as well it fits the spline count on your servo. I think you will have to user a shorter arm of that brand of servo you got or modify what you have.

Good luck.

mautro

I don’t think that it is a problem caused by the Servo arm. The clevise doesn’t reach the Flap’s arm/Phenolic horn.
This is my problem. It’s not in line. And there is also the tube of the wing which makes it impossible to drill another hole.

And it’s impossible to connect the clevise to the phenolic horn unless I’m totally incapable to do this job

Dave Wilshere

It looks like the horn has been installed too low in the flap at the factory. The horn/hole should be as high up as possible. It’s a pain, but I have seen this before on a Viper, I used a small long drill to work either side of the horn which is bonded into a block. It’s possible to break it out, raise the slot and Hysol back in.
The kit will have serial numbers on each component, make a list of the issues and email your Rep or CARF so they can check when and who assembled this kit.

Dave

mautro

ok. I will make a list so far. Thanks Dave

mautro

Dear all
could somebody post some pics of the linkage connection of the flap and also the position of the Servo? I tried the whole day to find a solution without success.

the red line is the way that the servo rod takes. Vertically up. How to get the flap up to 80mm?

mautro

Did somebody bend the rod?

Dave Wilshere

No...unless you lift that horn to the fibre glass cover vane it will never work!

mautro

I did it. Now the throw is like this....

mautro

...is it enough? Dave what do you think?

Dave Wilshere

Yes, looks good. The Tucano flaps are huge, so you don’t need extreme angles.

Well done, I know it’s not perfect having to redo something the factory did not get right, but it’s great when you can sort it out.

Dave

mautro

Thx Dave. You helped me a lot together with the others! Now I will modify the 2nd Flap. Finally I will start with the landing gear.
