RE: X435 vs Y535
The art of prop balance is not that big a deal. You can save lots of $ doing it yourself. You may find it more rewarding doing it yourself. But if you don't have a Dremil and a prop balance. Then you may want to buy them already S&B Use a mask when you sand ,Belium is toxic. Why they still use it, I'm not sure. If you use Stainless steel.use a mask I have gotten a migraine sanding props. I do try to be in a well vented room. But I have been around a metal grinder many years. One bad pit stop you'll need to fix it yourself. Them props don't like sand and gravel.
