After several years of development, the new Tribunus Series ESC's have arrived! This new generation of ESC is just what you need for your 700 to 800 size Electric Helicopter, or large scale electric airplane. Following the incredible success of the Tribunus 14-cell 200-amp ESC, Scorpion has now released the new 14-cell 300 amp model! This is just what you need for your power hungry F3S Speed Class helicopters, or other larger applications requiring a larger 300 amp speed controller. While this new ESC is designed to operate on 14 Li-Po cells, it can also be safely operated on 16 cells without voiding the warranty!

With the new Tribunus series ESC's, programming has never been easier. These speed controllers can be programmed 3 different ways:

        1) With the USB V-Link II interface cable using a PC computer
        2) With an Android based phone or tablet using an OTG cable
        3) With the Mikado V-Control Radio.

The 14S-300A model features a built-in SBEC circuit that is adjustable form 5.1 to 8.3 volts, and is rated for 10 amps of continuous current with peaks of up to 30 amps! The heatsink on the top of the ESC is pre-drilled with M3 holes to fit a 40mm cooling fan. In addition to soft-start capability, the ESC features an excellent built-in internal governor, and also supports an external governor.

"Mr. High Voltage" Bobby Watts, with demo flights by Kyle Stacy.
