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...
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)
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.
