From the rules page.
Please note that from January 1st 2010, 40MHz will no longer be permitted for use in feather weight and above. The only permissible radio frequencies will be 459MHz and 2.4GHz for these classes.
i have had issues with BR6000 and the dx6 binding and the robot not going to failsafe on my featherweights.
What would be the best setup for hellbent as i dont feel confident with the setup i have for the FW.
