My experience from Hitec gear is mostly positive.
I had a Challenger 720 that I used extesivly. Experienced broken control lever wires after a while. It did not cause chrash though because I was lucky.
Had some problems with oxides in servo-reverse switches, cured with 5-56 and some switching back and forth.
The double -super reciever worked flawlessly, never even close to a tiny glitch as long as it was feeded with the right voltage.
Servos worked nice too. Oxides on potentiometer races never occoured.
I have a Flash 5X now wich I have operated for 23 hours without any problems so far. Reciever is of another brand so I have no experience with the current Hitec recivers.
I think Hitec is good value for money and the quality is good enough for most needs.
Cheers,
Ikaros
