Turnigy Trackstar 150A GenII ESC

[Lizard]

Wanted to share some pics and infos about the Turnigy Trackstar 150A Gen2 ESC I recently bought.

The plan is to run the ESC in my XO-1 powering the Turnigy XK5682-900KV motor.

Generally, the ESC seems to be okay from a build quality perspective as far as I can see.

What's not so nice is, that the two PCBs are not soldered to each other, they are using pin-connectors. Not sure if that matters only in theory, but I guess this could be a source for problems, especially with offroad usage.

From a cooling perspective it's not too good IMHO. The FETs on the upper side have heatsinks that are soldered to the PCB, but there is air between the FET case and the heatsinks, so the heat has to travel through the PCB and then to the heatsinks. The lower FETs don't have any heatsinks at all, they rely on the PCB cooling path. On top of the heatsinks there is a thermally conductive pad which is needed to compensate for the difference in height of the heatsinks. On top of that, there is the orange heatsink.

The heatsink is screwed on from the underside which causes the PCB to warp a little from the pressure.

But that is actually a good thing if you want to improve cooling yourself, since everything can be removed. On Mamba Monsters for example, the Heatsink is glued to the FETs, impossible to remove.
