Hi all I am a rookie at the whole FBL system setup, but setting up the AR7200BX wasn't so bad....except when I was done...my tail servo is sloooooow, and not going to its end points...only moves a bit each way....I discovered though that in my radio I had the gyro settings at 50/50, so I upped the 0 setting to 65...low and behold flick flick quick went the tail pitch back and forth.....but, it seems to be in rate mode now where the servo stays where you put it and won't return till you move the stick back...how do I get it to HH mode?

Also my cyclic servos are still slooooooow, and don't seem to be close to their end points....I figure it has to be a setting somewhere...I'm using a DX6i, it's an Align 500 DFC Pro with a Castle 75a ESC DS515 servos cyclic, and DS525 tail....

Cyclic servos slow is normal. Your not in control of the cyclic servos anymore. Your just asking the FBL unit to move the heli. Only during the setup modes can you see the full travel of the servos.

As for your tail, look at page 22 and 23 of your manual again. purple is rate mode, blue is HH. Depending on the radio 0% gain my be 0 in the radio or 50. I believe your radio is 50 = 0. That means 65 is equal to 35 but one is rate and the other HH. I thought above 50 was HH but you might have the channel reversed so just trust the color.

Tighten it tell it loosens then back it off a quarter

Did You Set Servo Info??
With the beast X, you need to set the frequency and centering or pulse of the servos being used.
you can get this information from the beast X website. Look under downloads and then look for servoliste.
Your servos should not be plugged in to the Beast X until this info is set.
Hope this helps you out.

Yes I set up servos 515's 525 to blue and blinking blue as per manual.
The servos were slow, and only traveled what looked to me like a small amount in setup also on the cyclic s.
I have to be missing something here....I did see in my radio that my DR/EXPO was set 100/28 0, and 100/INH on 1. could this be a factor?
Doing the set up everything was fairly easy blade pitched to 6 degees,
and got 12+ but only 10- on the pitch ranges....
My tail setting seems to be on rate mode also because the tail when given input slides over, and stays there until I move it back....my light is blue also...I think that is HH mode??

Uh oh...yes my servos were plugged in when I did this step....what should I do unplug and go back through this step? or do I have to re do the whole thing again? :-(...

NO! The reason for unplugging and doing the setup once then plunging them in and doing it again is to set the freq and pulse before you plug in. If you've messed up and did it with them plugged in then the damage is done. Most likely you've done no damage though. The real danger is that when you power up if the pulse is off the servos could slam over to the extremes and hold there until they fry.

Clear all your expo and sup-trims. Make sure your pitch is set from 0 to 100 with no expo. Then go through the setup again. When you get to "G" you should be able to get full travel and the servos should move quickly. Make sure you go to 50% pitch and set you servo arms center. If you don't see full travel then your issue is probably in "L".

If "L" was set all weird then do the setup a third time to re-check the 6 degree setting in step "J".

Just to clarify, in step "L" you are telling the FBL unit how far it can move the cyclic before binding so you will go to full pitch and push cyclic forward and use the rudder to make it bind and then back it off just a bit. Then pull it back, then left, then right... Then go min pitch on and on.

When you done you should be able to slam the sticks in any direction or make circles at any pitch with no binding. However you should see extreme angels on the swash.

Hope that's all clear.

Yes sir! I got her working, I went back redid it all and low and behold full cyclic throws on all servos! I don't know where I missed something but evidently I did...she reads out 0 pitch, 6, and 12+/12- pitch! I did reset all settings also before re doing it, so maybe something in there was the cause...spooled it up but haven't done a test hover...winds blowing pretty good down here right now....
Thank you!
