Esc? Receiver? Transmitter? Regulator? Maybe one of their infamous soldering connections. I tried with no luck to diagnose the problem, but I had invested in a watt meter and instead of the standby current of .06-.08 amps, battery elimination circuit was pulling .40 -.50 amps, so it appeared one of my servos had locked/seized or whatever the term is. I bought 2 36's though so I bring out my back up. I get the blades up tp speed and it starts acting crazy. Different receiver and transmitter, and with no crash, no heat build up, etc., 2 36's go down in a matter of minutes. At first I thought the transmitter or receiver had gone bad, but I checked them for heat build up regularly and they never even got warm. I was going to ask the forum for a diagnosis, but after a few weeks on the shelf, I took them down and found that one aileron servo and one rudder servo were locked/seized. Once I unplugged them, the rest of the systems functioned normally with no more heat build up. Within a few seconds of plugging the servos back in, (I guess it's the voltage regulator or esc) whatever chip it is got very hot. I noticed a few people mounted their receivers on the side with the covers off to cope with heat build up. I found that there are 2 cutouts in the reciever to dissipate the heat, but Walkera put the adhesive strip to fix the receiver box to the copter, right over these holes, thereby defeating there intended purpose of venting heat.
