I just finished putting together my GP Easy Sport 40 with an OS .46 AX and a Top Flite 10x6 wood prop. It's the first ARF for me and I followed the directions exacly. I have the battery as far back as possible and the receiver just in front of the batt.

It looks as though I will need to add 4.5 oz of weight to the tail to get it to balance slightly nose heavy. Is this an insane amount of weight to add? Also, where is the best place to add this? Top or bottom of fuse? Site of horizontal stab? All suggestions and insight are greatly appreciated.
