I am considering ordering the plans for the 750 Beryl. There are very few of them here in the U.S. so I have never seen one in person. I used to own a Super Emeraude and it flew great so I'm interested in the Beryl. How thorough are the plans and how difficult is the spar to build? How airobatic is the Beryl? I spoke to one man here in the U.S. that owned a Beryl and he highly recomended building one, his had a steel tube fuse.
Are most of them in France wood or steel fuses?

Thanks,
Roger

Hi and welcome on our site Roger,
The Beryl is a great choice if you like flying the Emeraude. This version was designed for various uses, as traveling, training, sailplanes towing, flying in mountains, but his main use is for aerobatic flights training. According to most pilots, it can be compare with the CAP 10B, but in tandem configuration. The set of plans is always available in full version, you just need to order it by asking our member "GILOR" privmsg.php?mode=post&u=20
Approximatly five Beryl CP750 were built in France and fly now. Half with steel tube fuse and the other with the wood one. This choice depends on your ease with wood or steel tube technology. The owner and builder of the CP751 F-PHLM is now building another CP750 but with a wood fuse. I think he is the only person who can say you, with a concret sight, the which one you'd better build.
Don't hesitate if you want more informations.

Thanks that answers some of my questions. What is the difference between a 750 and 751?

Hi Roger

CP751 is powered with 180 HP engine

Greg : only five Beryl was built ? Why not so more for this wonderfull aircraft ?

Hello,
To my mind it is due to two main reasons: Firstly the Beryl is not as famous as the Emeraude, which stays the main built plane of all the CP's and even now. Moreover the fact that the Beryl is in tandem configuration seems to be a matter for most builders and pilots. We have already received phone call from builders who asked us if they could build a Super-Emeraude with the same structure as the CAP 10, and when we answer that the Beryl was designed for aerobatic flights like the CAP 10 but in tandem config, they usually respond that this configuration is less convivial. In other way, this plane needs more notoriety but his brother "Emeraude" makes him shade.

Does anyone know any information about this Beryl PP-ZRM. I would like to know more about the tilt open canopy he used. Where did he get it, does he like it....

Roger

[prographics2002]

Sorry guys the plane above is from Brazil.

Laurent are you planning a slidding or tilting canopy for your Beryl?

"I would like to know more about the tilt open canopy he used."

I don't know anything about that particular plane from Brazil but his canopy closure is very similar to the one on the RV-4 designed by M. Rick VanGrunsven. Also, the Zodiac 601 from Zenith Aircraft has a canopy closure whose latches permit to open or close it any time from either side! May be you can have a look at these.

I received my plans Monday for the Beryl and have been reviewing them.
Does the Beryl and the Emeraude have washout in the wing I cant see it in the plans? Am I just missing something?

Roger

[Jean-Claude Meunier]

Hi! Roger!

I gues the Beryl has some washout in the wings. If it is like the Emeraude and the Diamant (which I built more than 30 years ago) look closely to the drawing of the outer ribs and you will notice that the washout is taken care of by the way the ribs are dimensioned around the spar. When the ribs are placed over the spar the washout apears all by itself.

Hope this will help you.

[prographics2002]

Thanks Jean-Claude I'll look at that when I get home.

Roger

Hi Roger

You are working very fast, are you impatient to fly on this beautifull aircraft ?

The roger's CP750 is here --> galerie/thumbnails.php?album=48

[diamant78]

washout c'est un vrillage ?

Chris

[Jean-Claude Meunier]

Salut!

À ma connaissance, oui, washout = vrillage de l'aile ce qui donne moins d'incidence aux extrémités des ailes donc un décrochage retardé et moins de traînée en croisière.

Au plaisir!

[cp1315]

Salut

Pourquoi cette solution a t'elle été abandonné sur les Super Emeraude ?

Complexité de fabrication ou autres raisons ?

Merci

Hi Laurent.
So far the building is going fast and I'm having lots of fun doing it. There are several things I have been putting off because I don't know the best way to do them. I want to do a slidding canopy but havent decided how to yet. I will keep the pictures coming.

Roger

[prographics]

The plans are not clear on how to attach the hinge bearing to the rudder.
The plans call for "1-hinge bearing, 2-10-24x27mm bolts, 2-10-24 nylock nuts, & 4-wood screws" I am using the Aurora MM-5 bearing, does the bearing attach straight to the wood spar using a anchor nut or is there a metal plate held in place by the wood screws?

Roger

Hi Roger

Daniel has sent pictures about his modification in fuselage structure in rear seat, named "tube de torsion", he did'nt see this in your project and would like that you see it.

Thanks to him.

[prographics]

Thanks for the pictures. I was thinking about putting the master cylinders
on the rear brake pedals and that helped me make up my mind. Sorry for the late response I was in China for a couple of weeks for work.

The seat mount and modified tubing at the rear stick are not a change in the plans but only how he did his, correct?

Hello Roger,
Very very beautiful construction. I appreciate(estimate), I was a part wood of the cp 751b n°47.

galerie/thumbnails.php?album=33

I saw that you made owed the aeromodelling!

I had to stop the construction of n°47. But I decided to make him in version 1/3.

galerie/thumbnails.php?album=71

Could be exchanged our emails? I am everything your works closely

I cross(spend) by a software translator.

Still bravo Roger.

Friendly. Alexandre
