If it's under powered, then replace the engine with that larger OS 50. That will certainly move that CG forward. Removing the screws is a possibility, but make sure you glue in the tail feathers so that they are nice and square with the fuselage and in alignment with the wing.

I just pulled the 50 out to put in a new profile 3D plane. I just want to try and keep this skyraider flying with what engines I have laying around..
My only options, other than the LA .46 are a thunder tiger pro .36 and an evolution .60 ( which is to big )
I wonder if the newer Pro. 36 would have more power than the older LA .46 ???? Now that would be an option....
