Hi Rune

The fuselage is kevlar/carbon, it is very good quality, the surface is very smooth, in spite of it is a big fuse it is very stiff and it is light.

I like the view of a clear canopy, and the canopy is very thin (I don't like) and light.
I plan to save about 50 gram by removing the canopy floor so the interior of the fuse will be visible.

Hi Isaac,

Looking thru your latest post, I notice that you have angled the rudder post once already installed, which means you have taken (as shown) -+ 8mm off the fuz. Is this a weight saving issue? It seems like a lot of work to do this, than say glue an angled piece onto the rudder post.

Also a question for anybody in the know (Alejandro), does the Osmose have a tendency to be tail heavy?

Thanks
Roly

Hi Roly,

It is not a weight issue, this is the common way do the job.

About a tendency to be tail heavy, If you build the plane with fuel engine, I think you might be right. A few days ago I spoke with MONTEZUMA and he told me that he saw in the ARC version that CAMODEL placed the wing tube about 1 cm or so behind the mark on the fuse.

MONTEZUMA, it will be nice of you if you put here a picture of that.

Isaac Najary

Are you not going to have anything on the inside to spread the load other than those small washers?
the reason I ask is those washers appear albut the same size as the dowl plugs you inserted.
Ah yes, now I see the cross members.
Silly me.

Hi Najary,

I have a deluxe arf Osmose kit. I ordered the plane to suit a YS engine and two servos in the stabs.
The trailing edge of the wing is 1.5cm behind the rear mark on the Fuz. If your wing trailing edge matches the mark on the fuz then they are moving the wing location to suit the equipment used. If this is so then my CG will be on the wing tube ?

Hi Shane

The CG is always relative to the wing cord, if the recommended CG is 1cm behind the wing tube (So mentioned somewhere in this forum) so that should be the starting point. (Not on the wing tube).

Isaac , I have not done much plug in wing installations on composite fuselages so your pictures are certainly going to help a lot when I finally get to build my Osmose . The only thing I find not too clear is the tempory spacing pieces of wood you stick to the fuselage with tape ...Why do you do this ? Is this to ensure you dont glue the wing panel to the fuselage when glueing in the tubes etc? Thanks Juan

Hi Juan

You right, that is the reason.

Hello everybody! My name is Marcelo Colombo, owner of Camodel, which is the manufacturer of the Osmose. Due to my lack of time I am not a regular visitor of the forum but was able to observe a growing interest in the technicalities of the construction of the model. Santiago is going to be, from now on, the link between all of you and the factory conveying the official word on matters of our mutual interest and trying to be of help solving minor issues, answering related questions, giving hints and tips, and, basically, trying that all of you could fully enjoy the pleasure of building and flying this beautiful machine.
Thank you all for your choice and support.

Hi Najary,

From the latest pictures (No 8) it would appear that you may have a small amount of positive on the thrust line of the motor mount. Is this intentional or just the camera playing tricks on the eye?

As usual, excellent photographic coverage of your build, once again many thanks for taking the time to document it on such a monumental level.

Regards,

Andy.

Hi Andy

It is just the camera playing tricks on the eye.

Hi Santiago

I am very glad that now we could have some official answers to our questions.
I started this post due to the lack of manual instructions, as an ardent fan of CPRL designs I recommended all my friends here in Israel to order the Osmose kit and I promised to help them to build the kits. (6 planes were ordered).

Here are some requests/questions:
1. Please review this post from the beginning and let us know if I made any mistake in connection with the structure or the facade of the plane.
2. Please continue to review this post and let us know if you have any comments or guidance.
3. Please tell us these essential data (CPRL always provides them with his designs):
A. CG location.
B. Wing incidence (Relative to the stab)
C. Te Canalizer incidence (Relative to the stab or the wing)
D. Location of the Te Canalizer.
E. Recommendation for the controls throw ( High and low) and expo.
F. Wing dihedral.

Thanks in advance,

Isaac Najary
