i must admit i had lots of problems with interference on 40mhz.
all of my electronics is suppressed both when i was on 40mhz and 2.4ghz,
even though i could remove all the suppressors etc as they dont affect me
i dont wont to cause problems for others, well apart from the odd oota !
I think newly designed robots built with 2.4 will not fit suppression as they will
not have any controll problems, not realising they are creating problems for
40mhz users.
