If you moved it to aid getting correct CG without adding "dead lead" (or to reduce useless ballast) then you are doing exactly the right thing.
I commonly trim some foam to get the battery where I want it or to fit a larger battery. I'd much rather carry a larger battery than useless ballast.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

Good point FH, but I am doing it for three reasons. One, I hate the velcro straps, they were too far forward for me as I moved my servos to the rear bay and got rid of the tail weights. Two, the rats nest of wires always had to be moved in order to strap the battery. I think if I put in a foam battery bay I can route the wire thru the foam thus making any constant shuffling of wire almost unnecessary. Three, getting the weight in a more vertical plane will make the models vertical CG more centered. Less pendulum being down low. Might effect the roll rate and aileron throws. Right now, the rates seem kind of mushy, but that may just be my expo setting. I figure it is worth a try to make loading the battery easier.Don't just fly--WREAK HAVOC!!!

moving cg vertically changes the axis of the roll and how much you have to work to hold straight knife edge.
distribution of the weight side-side or up-down affects roll rate (how crisply it can do 4 or 8 point rolls). More weight out toward the tips means its harder to start rolling and to stop rolling. The closer the heavy stuff is to the CG the sharper your points and corners will be when trying precision maneuvers.
Some planes this matters more than others. Scale bombers never were meant for precision aerobatics.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

Flew mine this morning after having it hang from the ceiling all winter. It reminded me of how wonderful this thing looks in the air. Greased every landing. I can't say that about most of my other planes.
I must admit, however, that those big, fat wheels are somewhat goofy looking. May have to mod them up later with skinnier ones.

Broken props??
Admittedly not all my landings are textbook, but I have been going thru a few props. between flexible cowlings/motor mounts and lowering a wing on landing.
I have even shorten prop diameter by 1 inch with limited success. Unless it's a soft landing the cantilever nacelles flex the wing and dip down enough to hit blades.
Anyone else experiencing this have a recommendation?

PS. You can try some stronger MAS props but if you drive them under power into the ground, you'll either still break them or break something in the motor mount or nacelle.
