The full potential of the 850R can be exploited!

Reedy's highly anticipated Blackbox 850R Competition 1:8 ESC is now available to racers worldwide!

Track-tested and competition proven, Reedy's Blackbox 850R is a versatile and powerful ESC capable of winning at the highest levels of competition. A wide range of precision adjustability, excellent throttle and brake feel, and durable high-quality hardware make the Blackbox 850R perfectly suited for 1:8 Buggy and Truggy applications.

The 850R comes pre-programmed with settings that are suitable for most applications and track conditions. But by utilizing the Blackbox PROgrammer2, the full potential of the 850R can be exploited. In addition to working as an ESC programmer, it functions as a battery monitor and USB firmware update device.

The following functions can be modified and saved using the Blackbox PROgrammer2:

Overall brake strength, frequency, drag brake, initial brake, and punch can be fine-tuned to the perfect brake performance and feel.

Drive frequency, punch control, and dead band adjustability make the ideal setup possible regardless of the type of motor selected and vehicle being raced.

Motor Power
Timing adjustability can be useful on larger tracks or where a slight increase in power and top speed can help experienced racers reduce lap times.

Miscellaneous Control
Select between Forward/Brake or Forward/Brake/Reverse mode and adjust the BEC output voltage depending on the type of servo used and desired servo speed. Adjust the desired low voltage cutoff or disable it completely. The temperature at which the ESC cuts motor power due to overheating can also be adjusted or disabled. Reversing the rotation of the motor is also possible.

The Blackbox Programmer2 that was included with our ESC is compatible with the standard firmware installed in your 850R ESC. If you have purchased your Programmer2 separately, please confirm that firmware version EE460140 is installed.
