I sure as heck hope not. We already have warning labels up the wazoo everywhere we turn. We don't need anymore. What we need is some SIMPLE COMMON SENSE.

I think it's every RCer's god given right to go outside the manufacturer's recommendations. More power to you (literally) for having fun YOUR way. However, do expect possible failure and don't blame the manufacturer if it happens.

BTW, the X-1 with which Chuck Yeager broke the sound barrier was designed by the manufacturer, Bell, specifically to go beyond Mach 1. There was NO warning label on that aircraft for Chuck to go against.

By contrast, in 1963, Chuck Yeager crashed a Lockheed NF-104A Starfighter while trying to set a new altitude record. The aircraft exceeded the AOA limit of that jet at 104,000ft and fell in a flat spin to 11,000 feet. He badly burned his face, but AFAIK he did NOT go *****ing to Lockheed about not putting a warning label on the F-104's dash.

Chuck had common sense.
