Update: I was able to pull the wheel apart, access the spring, and stretch it to my liking. If you go little by little, reinstalling it after each attempt, you can soften it up without going too far. Mine has no center feel when all the way loose and a good amount of center feel when tightened up. Thanks for all that replied. I now love my futaba, and for the first time this weekend, forgot that I had a new radio while practicing. The entire process took less than an hour. I contacted futaba directly and was told there were no replacement springs available. My good buddy contacted a futaba tech and he could have helped me out if I was unsuccessful. Most radio springs are similar, so if you are afraid to stretch it, you can always try installing a different one.
