This Combo composed of the Justock 3650SD G2.1 21.5T engine and the new Justock G3S 60A XR10 ESC is the perfect combination for Stock competitions.
The ESC fixed timing, often required in races. So get ready for a fair and successful race. Thanks to the new programming possibilities compared to its predecessor, it is now also possible to determine the direction of rotation of the motor and set the BEC voltage to a certain value.

ESC features

Even more parameters available than the regular Justock G3 controller
(intelligent fan, freewheel, throttle initial force)
RPM limit up to 88,000 RPM instead of just 25,000 or 33,500 RPM
Perfect for competition thanks to the rev limits and Zero Timing
Freely selectable motor rotation direction (clockwise or counterclockwise)
Adjustable BEC voltage (6V or 7.4V)
Robust aluminum housing for ideal heat dissipation
Integrated capacitors as a space-saving solution compared to external capacitors
Various protection functions against reverse polarity, overheating, fail-safe and more
Possibility of firmware updates to always be up to date

Engine Features
Heat resistant magnet and double insulated windings
Precision bearings
Simple appearance and good heat dissipation
Linear and smooth control
Rebuildable design
