Mr. Gray Beard it sounds like you are into giant scale. How would you put that many on board a 60 size plane? I don't want to take a chance on burning out the reciever.
Try Gene. I just gave up what I thought of as giant scale and got rid of my big planes. I have stuck with 60 size for years and years and just like them better. I just finished a 1/4 scale though and it has a bunch of room.
I use the packs to CG the plane. I put the plane on the CG machine and tape the packs and servos on the outside of the plane to get the CG. Then I hard mount everything inside the fuse in that location.
The plane I just finished is the 1/4 scale and I had to mount servos and one battery in a set spot. That only leaves me with two battery packs to get the CG with. Depending on the CG will also tell me what size packs to use. AAA, AA or Sub-C. Your only talking two packs. There are two sides of the fuse. Mounting can be Velcro straps, a box they slide into, fiber ties. Let your thought process begin.
