RE: Will changing paddle angle affect windy day performance?
The only tradeoff I can see going FBL vs. FB is the setup. While I dont own a FBL (unless you count the mcpx...but its already setup out of the box)...Ive done some reading on it. And I think the learning curve to setting it up is more steep than regular gyro. Thats just me.
I do however agree 1000% on going to a 500. Bigger, slower, flies smoother for the most part. And best of all...not all that more expensive to fix a crash comparing to the 450.
