I must ad,
It was very easy for me to get thru the learning curve w/ the eclipse and it will shift positive or negative. Thats what sold me on this one. I'm a Futaba guy (7C) who went to a 8103 that I sold on ebay to end up with this radio that controls every reciever I own...even a Parkzone piper cub. The manual and the internet will get a guy thru anything with a little patience. I'll also add that tonight I found it necisary to bump my end points back to all 100% settings to keep good cyclic and with a little luck I'll be inverted over the wifes kitchen table tomarrow night.
