RE: dose any one have a plan of the sonic 500
I found my Sonic Instruction book, its 8ppgs, I can scan for you if you are interested.
There are some side views of the airfoil, but nothing big enough to make a template from unless you can resize the photos.
Also, these are instructions from the sonic arc that was out roughly 8-10 years ago, not sure if it is the same as the current sonic, although they look the same.
