Chris Stubbs wrote in message I'n new to this newsgroup, my interest has
been sparked after comming across
this website http://www.prismz.com/helio/ they claim to sell plans to
build
your own chopper, does anyone know of similar sites?? Or have anyone
made
something similar?

Many of the designs that are offered on that site are not proven designs.
The fact that few people invest their time and money in them should tell you
something. Experimental helicopters are not toys. The results of poor
engineering have deadly results.
