Wow, they've really raised the weight limit since I was flying models!

Also, the thermal fliers regularly exceed the 400 feet, don't they? Not
likely an issue for the dynamic soarers, I suppose. Personally, I've
never even seen a model while I've been flying, except waaay down there
on a slope soaring hill.

The FAA has this to say with regards to model aviation:

This document is 28 years old. Does the FAA know what's going on now?
