6. CONCLUSIONS :

The person that send me an E-mail on the 25th of september 2008 with a solution
for connecting a Graupner to an EVO-12, please contact me again; your E-mail was accidently deleted by my anti-spam filter

Far from pretending to have found appropriate solutions to the problem of compatibility for buddy box systems, I hope however that these few notes, resulting from my experiences, could be useful to you in order to help beginners of your RC-club, this without too much expenses for instructor or pupil.

I also hope to obtain supplementary information from visitors of this website over the world, in order to complete it and to satisfy your needs.

Greetings from Brussels and good flights,

     Olivier


Hereunder an overview table with compatibility between brands and types really tested by readers or by me.
