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?

Eric,

The document is current. Read the following regarding current
developments in UAVs and current model practice (same as 1981):

I repeat, AMA is not "law", just a lobbying group and insurer. I have
no idea from where the 55 pound limit comes.

DS, slope and thermal planes can all easily exceed 400' but FAA
recommends against such activities.

What is your concern with today's modeling practices?
