More minor addition:
The servo bracket (CR0703) for the gun elevation servo (CP0290) was locked on the bottom of the inner side of the front armour (CR0403).

It is made by steel, yet is free on the bottom. During the bench testing, with servo was working, it shows some minor strains under a torque generated by the servo. No much but observable.
So I drilled 3 holes on the chassis, 1 hole on the CR0703, and lock in another angular bracket (white one) that connect the CR0703 and chassis. I believe that will eliminate the minor strains at all.

I always used the hardwares available from shop. So the work looks not pretty. But I believe it will work well.
