Sorry to hear of your loss(es) andizzle. Even if you could pinpoint the actual issue you will always have that doubt in the back of your mind as to the radios reliability. IMHO You are making the right choice to replace it if for no other reason than peace of mind.
A couple of questions
Did the plane have an optical kill switch of any type? If so, Which one?
What batteries were you using?
What servos were you using?
Was this the first flight of the day or how many flights had it done before that on the day?
The reason I am asking is that a buddy of mine has had a similar experience as yours and is doing some research. It seems all may not be perfect in the A9 world.
I had a similar problem as you experienced (not with a Hitec - another of the "top 3" brands) and to this day, I can not consider using that particular radio. I also changed to the mighty Futaba and have not had the slightest issue since.
no there was no optical kill switch of any kind, i pretty much got it ready to fly from a friend
i cant remember the brand name batteries off the top of my head but everything was6 volt.i do know my ignition was a 2500 mah, my rudder was a 2500mah, and everything else was on a 4200mah battery. everything was charged up overnight and i did a extensive preflight (being a real pilot its just a habit and added insurance) checked every batteries voltage with and without a load. i made sure the reciever and antenna was well away from batteries and switches. all my servos are also hitec servos
my outlook is maybe hitec has outsourced work to save money and the quality control just isnt there anymore. all i know is im done with there radios
