The 2.4 operating frequency will be discussed at the next FRA meeting. There are potential safety issues to be worked out. ( These do not concern the frequency its self at the moment )
At the UK champs 2.4 users were allowed to keep their transmitters as there was only a few of them. A robot did have an out of control problem when useing 2.4. This is being investigated as to the cause.

Regarding weights etc, the FRA have had no proposals from the RFL to discuss.
We have offered the RFL a meeting to chew over things but so far have not replied to our mail.
