Itzik,
You are allowed to take few hours break and come to fly with us.
We flew this morning in a very strong wind conditions. I was a hell of a practice of P09.
Don't forget us...

Note:
This method is not recommended for internal combustion engines due to the strong vibrations.

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

Hi Isaac , from your pictures please clearify the following for me on the Belly pan attachment . What are the little black squares on each side of the locating pins ? On the front of the Belly pan you have a small bolt - are you going to use this to bolt the Belly pan down through the air intakes you made in the Belly pan ?

Thanks
Juan

hi Juan

The little blake spuares are soft sticker which I use to prevent contact between the belly pan and the fuse (see picture).
Yes I am going to use the air intakes as an access to the bolt.

Hi Najary,

What is the black stuff you're using to colour the epoxy?

Cheers

Hi Jason

It is pigment for fiberglass, can be found in stores that sell fiberglass materials.

Hi
Thanks your comments about the model. I answered your questions.
-Basicaly is all correct , later I will show you same pics about the building process in factory.
-The CG will be located between 33-35% of the main chord. Then the pilot can move as he prefers.
-The incidence will be 0ΒΊ on the stab and T canalizer and +0.25ΒΊ on the wing.
-The base of the canopy is the 0ΒΊ of the plane.
-Firts models was placed just behind the clear canopy, and the new one is on the fuselaje about 10-12 cm behind of the original place.
CPLR had proved it and he didn't find any different in flight, but is better for vibration because the fuselaje is more strong than the canopy.( especially with four stroke engines)
-The basic control trought are:
Low condition :aileron 25ΒΊ, elevator 20ΒΊ, rudder 20ΒΊ ( expo 30-35%)
Snap condition more aileron a litte bit more elevator.
Spin condition full rudder
These are the conditions which CPLR gave me and I am using for the first flies.
-The dihedral cames from factory.

Hi
Thanks your comments about the model. I answered your questions.
-Basicaly is all correct , later I will show you same pics about the building process in factory.
-The CG will be located between 33-35% of the main chord. Then the pilot can move as he prefers.
-The incidence will be 0ΒΊ on the stab and T canalizer and +0.25ΒΊ on the wing.
-The base of the canopy is the 0ΒΊ of the plane.
-Firts models was placed just behind the clear canopy, and the new one is on the fuselaje about 10-12 cm behind of the original place.
CPLR had proved it and he didn't find any different in flight, but is better for vibration because the fuselaje is more strong than the canopy.( especially with four stroke engines)
-The basic control trought are:
Low condition :aileron 25ΒΊ, elevator 20ΒΊ, rudder 20ΒΊ ( expo 30-35%)
Snap condition more aileron a litte bit more elevator.
Spin condition full rudder
These are the conditions which CPLR gave me and I am using for the first flies.
-The dihedral cames from factory.

I hope is info be usefull !!!

Hi Marcelo

Thank you for your answer.
Can you clarify:"...33-35% of the main chord", do you mean 33-35% of the mean aerodynamic chord ?
It will be clearer if you tell us the location of the C.G. on the wing root chord (fuselage side).

Thank in advance,

Isaac Najary
