Ok today I decided to do some work. So I figured out the most I coud move the 2lb weight was 1.5" so just had to use a 2x3 to make a block spacer, fortunately I had 2 bolts that were long enough.

So after installing it I reassembled the plane to check the CG and it's still behind the back of CG by 1/4". So I had a 3lb weight and with that it goes to the middle point of the CG.

So I need to decide If I'm going with the 3lb or stay with the 2lb. It flew ok with the 2lb just needed some down trim and now it will need less
