RE: GY240 or GY401 for my Caliber 30
I've bought a GY401 for my Caliber and it works very well with a standard futaba servo but I'm sure it'll work much better with a digital one. For light wind conditions, the standard servo seems fine for anything you do but when windy and hovering in a crosswind, it struggles a bit as it's not that quick. I bought the GY401 as I'm going to upgrade to a digital servo in the future. The remote sensitivity control and HH to standard mode switching is so useful. I no longer have to take off the body and adjust sensitivity pots with a screwdriver. I hope that all helps
