I just bought a goblin 380 using the AR7200BX mks hv93 cyclic and mks hv 9780 on the tail. I'm wondering if someone could help me with the cyclic servo frequency, the tail servo frequency and pulse rate.

Thank you.

Thank you. I ended up figuring that out. But the beastx doesn't allow for a 333hz frequency. Will 200 be ok? Or do I need to go get the USB programming link.

Not sure, never had that problem. I wonder if a firmware update would fix that?

Set them for 200 and fly. Less is ok, higher is not.

what he said...just did some research and discovered the same thing. From beastx wiki
"Also it must be said that not all servos can be used at maximum frequency even if so it is told on the servo's data sheet. Depending on air temperature, voltage level and heli size it is possible that servos can not be driven at their limit."

Thank you all for your help. I got the heli together and some of the programing and wiring done. Still have to set up geometry then buy packs while helidirect still has their sale lol.
