broke after a crash, main mast is not bent, but energy release through the frame. I do not want to disassemble the whole frame but fix it instead.

The frame is weak in places and needs some bracing when using the CCPM option to hold the servo tray from flexing.
These arrangements eliminate the play on the cyclic/collective controls and gives a more rigid frame.

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.
