Hey guys, i'm fairly new to heli's and I have a brand new kyosho caliber 30 coming and to get a peek at the build proccess of the ARF, I downloaded the manual from the kyosho site... for some reason the entire setup is for transmitter mode 1, I am in USA so I want to set up my heli as mode 2 (I bought a mode 2 transmitter)... I was wondering if the manual for both US and Japan/Europe have the setup only written for mode 1? If so, what is the basic difference between mode 1 and 2, is it in the servo/rx configuration,? or is it simply a transmitter difference?

Thanks!
