Hi Bonjour,
Thanks to take few minutes to fill in the questions for the making of the unit. I will do multiple groups purchased to reduce cost of parts. I can't spend 6hrs to build for free on 20 version, so by reducing the version option available and making bigger batch at one time, that will help to bring a collision avoidance system to all canadian pilot at a very low cost. Below you will find info on the unit and can also see a faq over jfairplane.com . Send the link to your friend pilot and aircraft owner. If everybody get it, everyone will be at safety at a price of an ... hamburger flight !
