Blade 400 drifting left with DX6i in Phoenix

[robm]

Hi,

I couple of days ago I setup my blade 400 with my Spektrum DX6i in Phoenix. When I lift up the helicopter it's drifting slowly to the left without touching the Aileron/Elevator stick. I tried several changed but without success.

The setup was done according to the thread: http://www.rcheliaddict.co.uk/451228-post12.html. I skipped the Fine Tuning Section.

Here is my DX6i setup:

SETUP LIST:
* MODEL TYPE: HELI
* REVERSE: THRO - N AILE - n
ELEV - N RUDD - N
GYRO - N PITC - N
* SWASH TYPE: 1 SERVO90
* THRO CUT: POSITION - INH
* D/R COMBI: D/R SW1 RUDD

ADJUST LIST:
* D/R EXPO: AILE 0 100% INH
ELEV 0 100% INH
RUDD 0 100% INH
* TRAVEL ADJ: THRO 100% AILE 100%
ELEV 100% RUDD 100%
GYRO 100% PITC 100%
* SUB TRIM: THRO 0 AILE 0
ELEV 0 RUDD <- 9
GYRO 0 PITC 0
* GYRO: RATE SW-GYRO
0: 0.0%
1: 100.0%
* THRO CUR: NORM POS L, 2, 3, 4, H: 0 25.0% 50.0% 75.0% 100.0%
STUNT POS L, 2, 3, 4, H: 100% 100.0% 100.0% 100.0% 100.0%
HOLD 0.0%
* PITC CUR: NORM POS L, 2, 3, 4, H: 0 25.0% 50.0% 75.0% 100.0%
STUNT POS L, 2, 3, 4, H: 0 25.0% 50.0% 75.0% 100.0%
HOLD 0.0%
* SWASH MIX: INHIBIT
* MIX1: INH
* MIX2: INH
* REVO MIX: INH

All switches of the DX6i are set to position 0.

My Phoenix setup: see attachments

Any help would be appreciated.

Best regards and a happy new year.

You haven't mentioned it above but you have trimmed it haven't you. You will get drift one way and to the helis left is normal, just add a little right trim.

every heli drifts to the left on mine so i just put a few clicks of right trim on...

All mine tend to do it, but I leave my heli's sometimes with no trim, as it seems to help with my stick inputs and reading what the heli is doing, notch the wind up, trim slightly out just like my heli set up, all slightly out Haha

I just set the "SUB TRIM: AILE -> 2" and the heli is more stable.

Thanks for your help.

To hover you need to tilt the heli to the right to balance the force from the tail rotor. When you take off the heli is level and will move to the left until tilted.

The left drift is caused by the tail rotor pushing the entire helicopter to the left. It's a side effect of the tail rotor counteracting the torque from the main blades and is called "translating tendency".

Don't trim out out if you plan to do anything other than hovering! If you do trim it out, you'll make flying other maneuvers more difficult.

Just get used to it; knowing that you have to apply a little bit of right aileron as you spool up (to prevent tipover) and in the hover is part of the art of heli flying.
