Hello, I have built a hexacopter with a DJI Naza controller. It's got a DJI Hexacopter frame but with the following setup DJI Naza + GPS Hobbywing Pentium ESC Turnigy Propdrive 35-30 1100 KV (very strong) 10x5 props which i've balanced a bit. The problem i have, although it flies excellent in manual mode, i cannot use the attitude mode, it climbs and drops and climbs and drops... and not a small amount either, atleast 2 - 3 meters. I have tried a bunch of gain settings,but i'm not sure the gain is the problem. I got me a program card for the ESC's , but i dont know if timing or break on off will make a difference? Anyone with experience in this? Thanks!
