Hello Paul
First of all, it would be a miracle For such a young company like Hitec, to have sales revenue that rivals two of the most well known, respected R/C company's on the planet. Actually, I have been flying with Airtronics, Futaba and JR for longer than 20 years, and with very few radio related failures, however I have had some servo failures in the past, mainly stripped gear sets and in a couple of cases loss of power within a servo. In most cases I was still able to land the aircraft. With all that aside, its the type of failure in the Hitec that keeps me from using one them in one of my $2000.00 - $10,000.00 airplanes. In these posts that I read, and from an incident I personally witnessed just ten months ago,
they lock up, [

] in most cases, it would be nearly impossible to recover an airplane without destroying it when one of the surfaces are locked hard over.

Just my opinion.
