I have read in the other post/reviews that these can be nose heavy out of the box. I have thought a little about moving the reciever back towards the tail in order to move the cg. And I don't know what a wing bay is so I am not sure if I can remove it D. I do appreciate the suggestions. I think maybe tonight I will check the cg (I know I should have already done that) see where in the range it is and play with throw tommorow at the field.
