Dualsky SUMMIT 30X 6V SBEC ESC
Description
The new Dualsky SUMMIT 30X 6V SBEC ESC is the latest 30A speed control from this excellent manufacturer. This version has a metal heatsink to improve the heat transfer and current capacity. This speed control works flawlessly with all brushless motors, not just Dualsky motors.The speed control is supplied with the brake ON, so no programming is required for glider use. Solder the brushless motor wires directly to the three PCB lands. Swap any two wires to reverse the direction.Like many high performance speed controls this Dualsky ESC uses BLHeli-32 firmare. This makes it very efficient and thus small. However it also means that a PC and an Aurdino Nano or a USB LINK for Dualsky Summit and Lite ESCs is reqired to program it, if required.Due to supply issues the ESC has been loaded with a development version of the firmware and needs a special version of the the programmer called BLHeliSuite32Test. Please download the .zip file from here, unzip it and run BLHeliSuite32Test.exe to configure the speed control. Telemetry is supported using the KIS 24A protocol and is output to a blue wire next to the RC plug. The data output includes:
Temperature - degrees C
Voltage - V
Rotation speed - electrical RPM - divide by motor poles/2 to convert to mechanical RPM.

Nice little ECU especially small for 30amp.
I’ve actually had 3 of these. One for me and the others two were fitted to models I’ve built for other people. They work really well and the 6 volt output is a good compromise if you are using HV servos. I did find one problem. If you are using a 2 cell setup, I found the motor would not start reliably. I discussed this with Neil and he suggested that the minimum voltage be reprogrammed to 2.7 volts per cell. I sent the units back to him and he adjusted them accordingly and now that problem has gone away. They were returned promptly. The issue did not occur when using 3 cells.
I haven’t tried the telemetry yet but will will see how that goes. They appear very well made.
