Default I can't figure out how to get correct pitch direction?

I've got my BeastX initially set up. For the life of me I can't figure out how to get pitch to go in the right direction.

When I give it positive stick on the transmitter I get negative pitch on the heli.

All servo movements are in the right direction. Everything is great but this one important part!

Please someone.

Did you toggle servo reverse on the pitch channel?

Are you talking about on the beast or the transmitter?

If I change just the pitch reversing on the transmitter that will only effect the pitch servo right?

I'm used to ccpm adjustments on the transmitter, this is confusing

I had the same problem. I tried all of the settings available in the MB and tried all of the combination's with reversing servos in the TX, nothing worked even though servo 2 and 3 were plugged in per the 120 degree diagram. I switched servo 2 & 3 wires at the MB and was then able to get everything moving correctly.

I hope this helps.

All 3 cyclic servos move in unison when I give positive and collective pitch. They just do it backwards from the transmitter.

Your welcome, I was desperate to go fly today.
It may also help that this is my 4th FBL controller.....
I may be addicted!

Your getting me all excited about flying with the Beast.

Sorry, should have ben more clear, I meant on the transmitter. Your transmitter should be in 1 servo mode, so changing servo reverse on your transmitter actually does not effect a single servo when using the BeastX. Instead it's effecting the pitch *channel* data that is being sent to the BeastX. BeastX then translates this in to the proper movements for all 3 servos.

this would have been the easier solution then switching the servos leads.

I wish it would have been, but that didn't work either. Had to switch the servo leads.

Guys you shouldn't ever need to swap the aileron plugs. You can take a correctly setup heli, switch the plugs, and with a different combination of reversing get back to the exact same setup.

In your case, with all 3 servos moving in the same direction, but collective reversed... all you had to do was reverse the pitch channel(channel 6 for JR/Spektrum) in your radio and the collective would have gone in the correct direction

It's written right in the manual.

With that said... there's nothing wrong with reversing the plugs if you find it easier to figure out.

I'm glade it's working for you now. Can't wait to see your maiden flight today.
