The question I have is where did the OP get this plane? Was it pre-built? If so, what does the builder have to say about it?

If not, well, if the OP built it, what did he/she use for instructions?

I would imagine that the instructions would spell out where to put the CG on that plane as well as to suggest where servos, batteries, and all other weighty components may go.

I also must join the posters that suggest that this may be a bit of an over extension of enthusiasm for RC flying. This is not a beginners plane. I would suggest that he/she put the plane aside and get something a bit less intimidating to fly and to build up the experience needed to fly that CAP232.
