Which ESC to match KDE3510 715kv motor

Guys, I am looking for some educated advice. I use KDE 3510XF 715kv motors on my hexa, these run on 4S max. Now I have a problem to select a proper non-KDE ESC that actually works well also with Pixhawk. Currently I have Hobbywing Xrotor 40A ESC and this one is not reliable, recently I experienced a crash caused by this ESC. One of the ESCs suddenly set max power signal to the motor and this cause an unstable situation because Pixhawk was not able to stabilise the copter and the copter made a flip when I raised the throttle because it was falling down fast… Now the result is that one of the ESCs is giving a bad signal to motor, maybe a recalibration would help but I don’t want to experience the same problem again. So I will rather buy a new better ESCs… The question is which one ? I don’t want to spend a lot of money for original KDE ESCs so I’m looking for some solid alternative. The Hobbywing Xrotor PRO 40A looks better http://www.hobbywing.com/goods.php?id=400&filter_attr=6481.6496
