Hi guys im just about done with Goblin 500 build, however i have ran into quite a problem. So i am running an ar7200, a talon , and a mini Hercules BEC, that is set at 8.4Volts, along with a full st of BK digital servos.

So i got everything wired up and plugged in the battery for the fist time. All the cyclic servos seem fine. However when i give input to the rudder i get nothing then all of the sudden FULL and then the servo appears to shut off? This i really sad, I really hope i didn't get a bad one, I would love any help thanks so much in advance

Cyclic servo frequency BK
ok figured it out, i had not set the tail servo pulse length and frequency now its good, however the cyclic servos have a frequency of 333, and the beastx only lets you go up to 200hz, without programming it through a computer... can I just run them at 200???

Yes, you will be fine. Run at 200 with no problem.

iKon, because I am connected to my heli, are you?

Thanks!, one more quick question, for the life of me i can not get the cyclic servos to operate correct. I have the pitch moving correctly all servos are working together, but aeleron and elevator are a mess... I have tried reversing the channels, didn't do anything, are the servos supposed to go in specific slots in the RX... I thought with eccpm setup doesn't matter, thanks

Yes, they do go into certain channels since the Beast X takes care of the ECCPM mixing. Check your manual to see where they should go. I don't have a manual with me so I can't check for you, sorry.

I figured it out the two aileron servos go in with aux 1 or the ael channel, the one that DOES matter is elevator, that one needs to the the servo in the front or the back
