I don't know much about the 2.4 band yet. But Im doing all of the recearch I can on this system.. I do not intend to know everything. I can tell you I know nothing other than how to bind the tx and rx and do all of the set ups on my planes. I like it I do!! But I also love the old 72MHz equipment.. I never had any trouble from the 72 band untill they put the implants in my neck..If it hadnt been for that I would still own alot of 72 systems.. That part I posted about 2.4 being illegle in Japan.. I was told this fron my cousin that also flys model planes.. He is on tore now.. But he was In Japan He told me Futaba 2.4 was not allowed for rc use there.. I don't have a clue if it is or isnt.. Either way it has to work for all of us here in the us.. I wonder if we are trying to use to many systems at once? Could this be what is causing conflict? Should they try to limmit how many people fly at once. Again I have no clue. So I will just wing it see what turns up. All of us are pilots of some sort.. We all have our likes and dislikes.. But we are all in this together.. And I love you all like brothers/sisters. moms and dads.. We will get through this one way or another I'm sure..
