Adding weights elegantly
Nose heavy isnt as bad of a problem because you can add a heavy hub or put the weights behind the firewall. For the tail, it gets harder. Sometimes you can drop the weights down the fuse, untill it balances out, and then dribble some epoxy down there. What works really well is peeling up a seam of the covering so that you can seal it down again without a patch. You just do that, and cut a hold in the wood and drop your weights in.
