Dear Mr. Stewart,
The system shown on the Richard and Judy show invented by Trevor Bayliss, would not pass any of the BSI Kite marking crtiteria (PAS 1188) The FPA advised Channel 4 of all the facts, however to date we have received no response to our enquiries to ascertain the validity of this untried or untested system. If you require a homebased system we suggest you look at the FPA members list and select a kite marked product, or a properly engineered solution .
