Zero Gyro Angle Problem

[Macgregor the Hammer]

Shipmates-

I've run into a snag with getting a zero gyro. I've been racking my brain trying to come up with a reason. I think all the problems started with adding the 454_EasyAOB_FotRSU + Manual Range and Mast Height mod. I deactivated them and still the same problem.

Here's my step by step:

Determine target speed with stop watch/distance.
Enter speed into TDC.
Determine AoB using Gutted's gyro angle offset chart.
Enter AoB
Set range manually, around 1250 yds.
I Do not use the position keeper!

When I verify my setup on the attack map, my torpedo track runs out ~500 yds. and takes an 80° dogleg toward the target. :doh:

I'm wondering if I mucked up my install somehow. The zero gyro method has been my 'bread and butter' tonnage method. :hmmm:

If anyone has some idea, please let me know. I'm getting really frustrated!
:k_confused:

Well I figured out where my problem is. The last couple times I have set up a 90° attack, I have used the target lock on the periscope. I completely forgot that the lock function sends the current bearing to the TDC. :doh: :doh: :oops:

Still learning...
