Help! it's all bass ackwards....

Newbie frustrations - I have a Trex 450 w/Spektrum S75 servos, AR6100 receiver and a DX6i radio. I have ESC plugged into Ch. 1 Throttle; Aile (top left front servo) plugged into Ch. 2 Aile; Elev (Rear "external" servo) plugged into Ch. 3 Elev.; Gyro (Align Head Lock) plugged into Ch. 4 Rudd, and Rudder/tail servo plugged into Gyro. Gyro yellow wire in Ch.5 Gear; Ch.6 Aux has the lower right front servo plugged into it (Pitch).

Ok, I spool up and tail rotor ok, but Blade Pitch is controlled by the DX6i right stick Elevator up and down (swash plate moves straight up and down main shaft), and Left stick up and down effects throttle but ALSO Elevation (nose up or down). It seems that left and right stick are reversed as is roll function on right stick. The only servo that is reversed in DX6i program is the Pitch (bottom front servo) as per manual.

What am I doing wrong here???

Much thanks!!!!

Sounds like you've got a Mode 1 radio there but for the odd interactions between controls. Did you select the proper swash type when you did the initial model config in the Tx? You want to choose 3 servo 120 degree..

This is what I found on the web.

Function - Port
Gyro = Throttle
Aileron = Aileron
Throttle = Elevator
Rudder = Rudder
Elevator = Gear
Pitch = Aux 1
Aux 2 = Aux 2
Govenor = Aux 3

That's for a Futaba radio with a Spektrum RF module installed. The original poster has a DX6i...

[starpower4u]

yes. I'm set-up for 120 swash. Mode 1 is it? Huumm, the manual gives no indication on changing Modes, but it does mention Mode 2 is used for Airplanes and then in Heli program it shows the controls as right stick being Aileron/Elevator and left stick is Throttle/Rudder. this is Mode 2 also. Any more ideas???

With much appreciation...

Check your Swash Mix and make sure individually that your servos are performing correctly (check N / R). I was in the same position as you a couple of days ago and then a friend sent over the Finless Videos on CD for me. You should have a look at the CCPM ones.

Quick servo/CCPM setup "tutorial":

1st step. Get the servos moving in the same direction when working the left stick forward(up) and back(down) Doesn't matter if they're going the wrong direction, just so they're all moving the same direction. temporarily slip a control horn on each servo. If you've got the head on and hooked up, that's fine. Just make sure you've got the horns hooked up so they're parallel to the boom with both sticks in the center.

Now, enter the servo reversing menu on your radio. Move the left stick up and down. Either all 3 servos will be moving in the same direction, or 1 will be moving opposite of the other 2. Simply reverse the direction of the oddball servo's channel so all the control horns move up or down together. Once they do, you're done with reversing on the head.

Now, we need to get the servos moving in the right direction. Enter the Swash menu on your radio. Move the left stick full forward (up). All three servos (and the swashplate if hooked up) should move up. If they go down, simply change the value in the PIT mix to its opposite. i.e if it's currently +60, change it to -60 and vice versa.

Do the same for ELE and AIL in the swash menu, but use the right stick. Right stick up, the swash should tilt forward - rear servo up, both front servos down. If it's backwards, switch the value in the ELE field. Now to AIL. Stick right/left, swash should tilt right/left respectively.

Once you've got all the servos and functions moving the right way, you're good to set up the head.

If you haven't seen 'em, the CCPM1 and CCPM2 vids HERE (http://www.helifreak.com/showthread.php?t=11373) will be of great help..

Skiddz you da man!! That was it - the swash mix and servo reverse were both wrong. The manual and others on the forum all said the same: Ail -65%, Ele +65% and Pit +65%, mine is working correctly now at -65%, +65%, -65%. On servo reverse again manual and most said all Normal except for Pitch to be Reverse. I'm good to go now at all Norm except for Ele and Pitch both are Reversed. Same servo's and mounting orienation as manual suggests, I suppose that the "newer" DX6i radio is different from the DX6 that I suspect the manual was written for. I did go over all of the the Finless vid's but I somehow got this wrong.

Thanks again to all of you that tried to lend a hand!!

Yeah, don't get all hung up on other people's numbers. Your machines WILL be different. I have 3 450s and none of 'em are set up the same in the radio. Identical pitch ranges and curves, but the reversing and swash values are all a little different.

Amazing how simple it is once you understand the hows and whys of reversing and Swash values, huh? :)

Glad ya got it sorted out, now finish setting it up and post some pics of it flying!!
