Some remarq about the original Frame: This is what a roswell look like when you first buy it. After some pratice, you will rapidly notice that the main frame (for me a big piece of shit) break easily in many places. That's because it was designed for flying indoor. After gluing together the parts, I decided to replace it with something stronger.

Pictures are like thousand words, so if you need more explanation, feel free to contact me...

First Idea : redo the frame in the same material.

OwnshitFrame.jpg My first attempt : using the same material as the original frame ("carton plume"). It is really cheap, lightner than CFK but I decide it was not the way to go.

Second idea : use gfk and add glue in some place to improve the original frame
not tested.

thrird Idea : do a new one with aluminium tube (instead of CFK, wich is really too expensive)

side.jpg yeah i am using small rope and CA glue, it is as strong as carbon	kitchenAir1.JPG it is light and strong, maybe a little too heavy	Kitchenair2.jpg
electronic.jpg The electronic circuit is mounted on top	general.jpg final look of the roswell	below.jpg I still have some problem to mount battery in it
generalbelow.jpg Symetric mounting as required by the original frame	side2.jpg Do not forget to cut 2 tennistable ball (ping pong) for protecting the motor connections.

Total cost :

• Aluminium pipes : 12 FF
• Epoxy glue (90 seconds) : 35 FF
• Kitchen Aerator : 25 FF

4th idea, build a bigger roswell based on the small one.

On order to reuse the computer board, i will use new transistor (same reference as the original, it is only for protecting the board) and dissipator. The circuit board is using too small printed circuit. So I prefer to make an external power circuit.
