The tiger Moth, a rudder trim issue ?

[Athos1660]

Like in real life, the in-game Tiger Moth has neither aileron trim, nor rudder trim.

However, it seems it is not even in trim with rudder when at cruising speeds which is expected (whatever the mode : easy, normal or realistic). Whatever the speed is (even low such as 55 mph), it rotates counterclockwise.

 

 

 

 

btw I don’t get the same result with other planes (D.520, Spitfire...) : they are in trim with rudder at cruising speeds.

 

Does anyone have the same result with the Tiger Moth ?

.. or is it a plane with which you constantly have to compensate for engine torque using ailerons (whatever the rpm) ?

Hello Athos1660, I see the same thing, the Tiger Moth in CloD does have a slight tendency to roll to the left at the cruise airspeed and rpm settings you mentioned. Altitude has some effect on how noticeable this is. We saw a similar, but considerably worse, issue with the Gladiator several years ago. You may find it useful to review the discussion of that situation here: https://forum.il2sturmovik.com/topic/68556-stong-roll-when-flying-a-gloster-gladiator/

1) Thank you so much for your reply and these explanations. Great to know this ! 🙂

 

2) Unfortunately I tried the Tiger Moth at high altitude (above 12000 ft) at level flight and got the same result as at lower altitudes, whatever the rpm : it rolls counterclockwise. Did I miss something ?

 

At 80 mph, 1900 rpm :

 

At 60 mph, 1450 rpm :

 

At 87 mph, 2250 rpm :

 

3) I also tried the Gladiator. Indeed it got the same tendency to roll, it clockwise.

 

More precisely, I found that, at 2000 ft :

- the Gladiator is balanced for 1340 rpm and 110 mph (which is very low as the flashcard says for cruising : 170 mph, 2200 rpm),

- it rolls counterclockwise at < 1340 rpm,

- it rolls clockwise at >1340 rpm,

 

... unlike the Tiger Moth that always rolls counterclockwise, whatever the rpm.

 

Poor fixed pitch prop planes 🙂

The Tiger Moth 1940

Altitude : 11 800 ft.

2475 rpm.

Still rolling counterclockwise.

No, it always rolls left (CCW) for me as well, at cruise conditions.  I only mentioned altitude because in the limited testing I did, it seemed the tendency to roll left was stronger at higher altitude.
