We now have inventory, and will be listing, a low profile replacement heat sink accessory for the Havoc 1S and Havoc 2S for use in single cell racing. It is the existing HS with the cooling fins milled down.
We are also working on a less bulky TransCap module that can replace the module that is furnished with the controller; this new module will be for use with high wind spec motors only. The existing 2S TC module is optimized for low wind motors.
