Hi Randy,

I have a strange intermittent problem with my Tekin RX8 speed controller. Occasionally (usually after a lot of high speeds) the controller seems to crash or something. It often happens whilst I am full on the throttle, which is not a good time to lose control of your car. When this happens, all power to the servo and radio receiver is cut/lost. Also, all the lights flash rapidly on the rx8 speed controller. It will remain like this for about 20 or 30 seconds, and then come back to life. If I start driving straight away, it will often cut out again within the next 5-30 seconds or so. But usually if I leave it for a few minutes, it will be fine for good after that.

Someone from Tekin told me that the rx8 speed controllers flash all the lights when they lose connectivity between the esc and radio. So, this is obvious because all power to the radio has been cut. The question is why? Can you think of anything in the esc that would cause it to stop powering the radio?

At first, I thought it might be the thermal cutout, since I was racing it at a track and the esc fan had lost a few blades, but I've now replaced the fan, and it still does this cutout, even when the esc is running cool.

I've got a lipo battery tester/meter on the battery testing for any dead cells, and there are none on the battery, they are all good. When the esc seems to lose power to the radio like this, the lipo battery meter doesn't show any problems with the battery.

Oh, by the way the radio is a Spektrum DX2S with an SR33001 receiver, which also has a thermal probe going to the motor which tells me on the transmitter the motor temperature. It is about 2 months old.

Any ideas as to what might be going on?

Any ideas on some tests I could do?

Thanks.
