Running out of nose up trim

[Flamin_Squirrel]

Anyone else running out of nose up trim, especially when landing?

[Hueyman]

Same here, probably like in real life ... ?

[AndyJWest]

Yup, same problem.

[NineLine]

I think the D-9 was well known for limited in air trim options...

[Flamin_Squirrel]

Maybe. Doesn't seem right that you'd build a trim system that doesn't have enough range of motion to function during a critical phase of flight though. Especially something German!

I think its because most of the trim was done on the ground though... so maybe you are seeing a limitation from that, although I hadnt noticed it myself.

How steep is your approach path with full flaps? The final flap setting at 58˚ could mean the aircraft requires a rather steep approach angle, perhaps doesn't need that much up trim there.

 

Sorry, haven't been able to test myself yet.

I wonder if the same was true for Antons. Maybe lack of nose up trim is Dora specific, due to different engine and longer nose. After all Dora wasn't designed from scratch.

Gentlemen, you make me wondering... even with default settings full stick aft stalls the planes both in clean and landing configuration.

 

If you maintain recommended 220 kph at final, the plane flares to three point attitude easily.

[Flamin_Squirrel]

Not sure what you're saying there Yo-Yo. I can land the thing at 220kph no problem, I just have to keep constant back pressure on as there's no more trim.

exactly...

Ok, I understand.

[Flamin_Squirrel]

Ok, I understand.

 

Ah, good!

 

I also find I need back pressure on takeoff, even at the specified speeds.

 

Perhaps the trim is offset or something? Hopefully it'll be looked into, even if it turns out I'm talking rubbish :music_whistling:

That is odd. "Let her fly herself off the runway" ... at first I did make the mistake that I applied back pressure (tail wheel lock) a tad bit too long. She jumps into the air, stalls and crashes ... Now, after this lesson learned, when I recenter the stick at ~ 150-170 kph she lifts off so gently you barely notice. No stick input required at all. (but flaps in T/O position, ofc)

I gather some variants of the BAE Hawk are a little bit like this IRL :)

I'm not really having much trouble with Up Trim, but is there really No Trim for Rudder or Horizontal Trim? I ask as I am setting up my Warthog and can not find key commands for these functions. I read the flight manual and it doesn't refer to these functions either.

A little confused, but lovin it :D

Nope. The Fw 190 (like the Bf 109) had no rudder or aileron trim.

[javelina1]

wondering why? the German's declared, we don't need that??? ;) :lol: :)

[Spasticatedtoad]

Wow! Thanks for the info

I too find it a little weird. Considering how advanced this plane was for its time, I would have assumed Aileron and Rudder Trim would be a given. :joystick:

[NineLine]

Most of the trim was done on the ground, no controls for the pilot beyond what we have now.

Exactly!!!

also known as stabilizers for German planes not trim.

the wlole surface moved up or down!!!

[Foul Ole Ron]

Rudder trim being absent always seemed a strange design decision to me. It was something that test pilots who flew captured versions always commented on about the 109 and 190.
