Spirit System

Hello all together,
I flew yesterday with my TRex 550X (Spirit Pro, Setup mostly default settings).
Wind speed was approximately 25 km/h.
After or while a climb with full pitch I wanted to make a rudderturn to right side, but the heli did not or only very slowly react to the input. Left rudderturn was o.k.
I tried then rudderturns in both directions in normal pitch positions and all was o.k.

Is this “weakness” of right rudder a normal behavior because of the torque of mainrotor or have I to change my setup?
Thank´s in advance for every hint and with best regards

Hello,

this could happen, if the head speed is too low / rudder efficiency is too low.
If it is mechanical issue, you can only increase the RPM or use a longer tail blades.
If it is configuration related, then you can increase Pirouette Consistency by 10 - 20 points to make it better.

It depends on what RPM you are flying?

Hello Tomas,

thank You very much for the quick reply.
Align offers für this Heli tail blades with 90 mm and 95 mm. I ´m the 95´s.
Head Speed RPM was 2000 rounds in Spirit Governor Mode.
I think, I will try to increase Pirouette Consistency and will give a feedback then

With best regards

You can try to increase to 2200 - 2300 RPM. This should be optimal headpseed for this helicopter.
For 3D they are using even 2500.

O.k, thank You.

I will try this too.
