Hey guys, I got most of my problems fixed except for one. My right stick is FUBAR? When I push right or left my swash plate tilts up and down, when I push up or down on the stick I get left or right on the swash plate? I have tried both swash settings, 90 and 120.......... What do I need to do now, any advise? Its a blade 400 with a dx6i

The crystal ball is cloudy so we can't see what helicopter and radio you have...

I'm not being mean or anything, I'm saying this in the nicest way.

Take 2 seconds and think about it...

also, what heli/receiver/radio?

Oh wow! I wish my transmitter said "Touch Your Dreams!"

have you unpluged any thing from the receiver? maybe you pluged every thing back in wrong? or you need to reverse the servo settings in the radio

I'd call the suport number they will talk you thru it

Typical RC car guy converting over to helis.
Instead of giving complete details or thinking about the problem, it is easier to ask away.
It's not that we don't want to help, it is just that we expect you to be able think about things yourself so you can learn by your mistakes.

The blade 400 uses 120 degree ccpm.

The way I set up all my 120 ccpm is in this order, regardless of heli make works every time and take 10 mins to set up.

First find the elvator servo, on the blade it is the servo in the front of the helicopter that connects to that bellcrank between the frames. It is the only servo of the three that will not move when you use aileron control (left and right) with the cyclic stick.

Now plug only the elevator servo in (don't worry about the other two at this point, you'll get to them one by one). The easy way to work it is as follows: little bit confusing, I even confused myself right now and had to pull out the radio and take a look real quick to refresh my memory.

Simple way I remember it is:
If the cyclic for the elevator is correct(on the blade meaning the servo pushes the swash up when you pull back on the cyclic stick), but the collective is reversed, then you have to reverse the swash mix first (so if at +50%, reverse to -50%) and then you need to reverse the servo.

Is the collective for the elevator is correct(meaning goes up and down in conjunction with up and down for collective) but the cyclic is reversed, then you have to reverse the ATV for the servo first and then reverse the swash %.

If both the collective and the cyclic are reversed at the same time, simply reverse the ATV on the servo.

To summarize:
1: Cyclic Correct - Collective Reversed = First Reverse swash mix %(-or+) THEN reverse ATV.

2: Collective Correct - Cyclic Reversed = First Reverse ATV THEN Reverse swash mix %

3: Cyclic Reversed - Collective Reversed = Reverse ATV

Do the same for both other servos using the same principles by adjusting them using the ATV's and swash mix.

PM me if you have any questions and I'd be happy to help out any further.

Let's see...a Blade 400 with a DX6i.

CCPM swashplate. Set the DX6i swash menu to select three servo, 120 degree CCPM.

The servo that controls the front ball on the swashplate plugs into the Receiver's ELEVATOR channel.

Of the two remaining servos, one plugs into the AILERON channel, the other plugs into Aux 1 -- channel 6.

-----

Move the stick side to side. The two servos controlling the rear of the swash (aileron and pitch channels) need to move in opposite directions...one goes up, the other goes down. If they both move in the same direction -- go to your servo REVERSE meny and reverse one of them, it doesn't matter which one. Don' worry if left and right seem to be backwards at this point.

Push the stick forward and backward. The two servos in the rear must move in the same direction -- both UP or both DOWN. The one servo in the front must move OPPOSITE direction. If the two in the rear go UP, the one in the front must go down. If this doesn't happen, go back to your reversing menu and REVERSE the ELEVATOR channel. Again, don't worry if the swash tilts the wrong way at this point.

-----

Move the stick to the left. The left side of the swash must tilt DOWN. If it tilts UP, go to your DX6i SWASH MIX menu, and change the sign of the number associated with the AILERON function. If the number is +65, make it -65....

Move the stick forward (toward the top of the TX case). The front of the swash must tilt DOWN. If it doesn't, go to the SWASH MIX menu and change the sign of the number associated with the ELEVATOR function. If it's -65, make it +65.

Move the collective pitch/throttle stick UP. The leading edge of the MR blades must move UP. If they don't, go back to that SWASH MIX menu and change the sign of the number associated with PITCH. If it's +65, make it -65.

The servos are all now moving correctly with respect to each other, and with respect to the sticks. Finish your setup and go test fly to fine tune.

Thanks guys, rather than making someones problems worse you offer support rather then a negitive post, Thanks again.

BTW - in a CCPM setup, you don't mess with the individual endpoint adjustments (ATV) for the aileron, elevator, and pitch channel UNLESS the swashplate does not stay level as it moves from full down position to full up position. Those individual ATVs would be used to correct for a servo that either travels too much or too little when compared with the other two servos driving the swashplate.

It's quite often something you just leave set at 100% and never have to touch.
