Looks like the response will exceed the "5" threshold
In addition to turbine stuff I'm still flying an OS91 d/f Enforcer just to pull folks' chains and plan to build another. The ByroBlaster stuff just works better at our rarified altitude.
Then there's electric ... oh, shoot, I don't have any (yet).
Nah, d/f isn't dead and there's obviously a lot of grass roots "support" for it. I think most guys continue to enjoy d/f stuff at their local fields.
