What causes the TB-3 loss of direction change?
 

Was trying to rebuild some old missions and the TB-3 can't do course adjustments when looking through the bombsight anymore. Any idea what causes this and is there a work around until the next patch?

how do you make course adjustments in previouse version? as far i know there was no trimmer on TB-3 and i always make course dirrection shortly disable level stab give some rudder and switch on level stab again.. on TB-3 mostly make course adjustments by throttle by right or left motors.

Since the TB-3 had no trimmer, I have found the same work around as you to make fine adjustments using engine power. I normally set power to 90 or 95% depending on the model, and then select engine 1 or 2 to slightly change, or maintain, my course by increasing or lowering power by 5% on the selected engine. I also trim all the way up to try to maintain altitude as best as I can but that eliminates the possibility of using heavy bombloads and full fuel tanks.

refresh my memory, when on TB3 was Trimmers?
or no ...how do you make course adjustments before?

The TB-3 has a trimmer for the horizontal stabiliser.

in 4.13.4 i haven't it on TB3 ... or what i miss?

i just check three version of TB3 on 4.12.2 and 4.13.4 and don't find rudder or aileron trimmers ...

yes Altitude trimmer we got on TB3 like it was before ... but i don't remember rudder trimmer on TB3 with old variant of bombsight.

I used to use rudder trim while using level stabilizer,same as with il4 and pe-2/or-8,A20/B-25, I set keys ctrl z and ctrl x for rudder trim. Basically same procedure as in the training track and the opb 1 video you guys posted as bombsite tutorial.

This as well for opb 1

trimmers isn't part of OPB-1 ... ofcourse on Il4 SB2 Pe2 Pe8 you have trimmers and you can do that course adjustments.. TB3 haven't rudder trimmers in old version ... was just replaced old strange bomb sight to OPB-1 and all other part was stay the same ...
or you some how use trimmers on TB3 with old bombsight in 4.13.4?
