My friend and I have a 100% perfect product that keeps all ice and frost from ever being able to form on the wings or horiz stab, regardless of how long it stays outside and how bad the weather. G5 would cost approximately $10,000 to purchase and a Lear 55 would cost approximately $3,000. 50% of those costs if you just want to protect the wings and then deice the tail only if needed.
But start-up costs will require about $250,000 for the manufacturing set-up fee's and some special "stuff". I have an investor considering it.
It will take about 20 minutes to set up on a G5 and about 10 minutes on a Lear 55...after the crew has parked the plane. Same time to prepare it for flight.
No STC required or FAA involvement of any kind.
We should have a prototype ready for next winter for a Lear 55 and Challenger 600. It can also keep anything from forming on the aircraft from the cabon door forward all the way to the nose.
Never having to deice wings or tails again should have some interest with aircraft owners.
