I've been in the hobby for a very long time. Most kit and plans builds show a very conservative CG location. To improve performance, in most cases the CG must be moved rearward. How do most of you do this? I cut a small hatch in the tail and add lead shot until I get the performance I want. Then I glue the hatch back in and recover. I've been debating adding a permanent hatch during the build to help do this rather than just cutting into the tail. Any ideas?

Adding weight is the last resort, relocation of servos and batteries is the first thing I'll try

Relocate the hardware, battery or servos or both.

I do the same with hardware. I run velcro strips and move the battery around.

I agree with everyone else....move stuff aft before adding weight...I have cut open the belly of an airplane glued in a platform and moved batteries further aft to keep from adding weight.

As a builder I get my planes finished and in the bones, I then use tape and just tape my gear to the outside of the plane while the plane is on the CG machine. I also add the control rods in there general location. Once the CG is achieved I hard mount everything. I like to make a long table type of gizmo over the CG with Velcro on the top so I can shift the battery back and forth to change the CG as needed/wanted. Sometimes lead is the only way to get the CG I want. I don't like adding useless dead weight but sometimes you just gotta do what you gotta do. I also keep a couple of Sub-C battery packs on hand just in case I need a bunch more battery weight.

Hi!
I do as Gray Beard. Move things untill the Cof G is perfect. Takes some time though.
Never add any weight if I can avoid it!
