When the 6-meter band actually opens that area is packed. I sure 
wouldn't want a $5,000 plus model controlled on those frequencies.  I 
doubt even most of  today's hams are aware of their existence. Only 
those of us from the "old days" when that was highly popular.  Even then 
there were problems, probably more so than today when digital is  about 
the only mode used. 

Wayyy back...in the 60's or maybe earlier, a friend who was a ham and RC 
modeler lost a small plane when a station came on about a mile away and 
the plane failed to respond.  He found the wings outside a greenhouse.  
The rest was inside.

I can't imagine any ham in their right mind using any section of six as 
the risk is just too great. I wouldn't even use a learners model in 
there.  They might get away with it for years but sooner or later, some 
one some where will come on with the inevitable result....  At least 
today's *good* RC gear is much less prone to interference than the stuff 
we used to use.
