Greetings all,
My son and I are nearly finished with a Dura Plane Dura Stik 40 and are trying to correct the CG. It says to balance it at 3-3/8" from the LE by moving the battery(ours is a 4.8v, 600mh) back and forth on the nose. When I place the battery all the way to the front of the fuse, I still have to add 7 oz. to the front to balance it!!! Yikes!

I'm using a OS Max .40 FP engine and I'm using 3" wheels instead of the recommended 2.5".

Is this ok to add this much to the nose?

I appreciate any comments or ideas.
