HDX 300 reversed pitch

[kyoung4587]

I am building a HDX300V3 and have everything working well except that when I give high throttle I get negative blade pitch swash up and when I put throttle to zero I get positive blade pitch swash down. I followed videos and can't figure out how I got it backwords. Please Help.

I am going to assume that every other function with the swash is working in the proper directions. Not sure what radio you are using but reverse the numbers in the swash menu
If you have a lets say positive 65 then go to a negative 65 everything should be cool

Ijust watched finless video for the 300 the video labelled servo install and setup explains this in detail

I would think you need to switch the servo reversing on all 3 servos. Its a bit dangerous but you can spin up the rotor on the bench (make sure its tied down or held down) and move the cyclic to make sure the rotor disk is moving in the correct direction. If its not then just switch the servo reversing. If it is then make the change in your swash mixing.

I just went threw all of this with my Honey Bee King v2. I had a DX6 and waiting on a DX7, plus I am using eCCPM. If you have mechanical CCPM it may be different and just need servo reversing. But in my TX setup I had CCPM1= +50 CCPM2= +50 CCPM3= +65 and had what you are describing. My fix was to change to CCPM1= +50 (aileron) CCPM2=
+50 (elevator) CCPM3= -65 (pitch). Hope this helps...

You dont want to do the servo reversing, rather you want to reverse the CCPM mixing for pitch in your radio. IE if it is say at 50% now, reverse it to say -50% for the pitch mix. Then the stick will do what it is supposed to do.

edit: So I just noticed that TheWheelieKing just said the same thing.
