Re: Topband: Drones for antenna installation?

[David G4FTC <g4ftc@hotmail.com>]

The one thing that scares me with the tennis ball launcher is the risk of the 
plastic air reservoir exploding - probably not a problem with new pipe but as 
the pipe ages I would expect the pipe to become brittle and that brittleness 
may not be easy to detect until it is pressurised.

The sling-shots do have the problem of the rubber tubes perishing - but a 
visual check will easily detect this.
