I thought you were using flexible pushrods.
You are using straight pushrods.
This will work better:

That plane is long gone! Can't share any more pictures.
Refer to my thread to see if any of those pictures help you.

No!
You'll just have to move the battery a little forwards. Since you have a 1500 which is much heavier, you should be fine. Infact, the servos at the tail will help you balance.

They should be as recommended by Flitetest.
Share picture of your pushrods, servo placement and control horns please.

The recommended throws are half an inch. One side is a bit more than half inch.

You can either trim your servos to correct your problem or re adjust the servo arm.

Put hook Velcro beneath the power pod (full length)
And the loop Velcro on the battery. You can move the battery to attain CG then.
Your throws should be according to FT. If they are, then fine.
Are you getting equal deflections both side with that servo placement? If yes, then they are okay. I hope the control horns are installed correctly..... With the pushrod over the joint.

Show me the side view along with the control horn.
In my opinion, the force vector is not straight. So one direction won't be getting full throw.
