HobbyStar 155A ESC, 8A SBEC

SKU: 361-21-155

Availability: In stock




HobbyStar aircraft ESC's are top-of the line, full-featured ESC's at a competitive price.  Constructed using only the highest-quality components and are encased in a beautifully machined heatsink housing to help keep operating temperatures in check.  The integrated switch-mode BEC allows you to power your servos and receiver without the added complexity and weight of a separate BEC.  Specifically designed for higher-current applications to eliminate the possibility of unwanted shutdowns they are capable of supporting simultaneous multiple current loads as found in large scale airplanes and CCPM equipped large-scale 3D helis.  Includes mounting bracket for clean, sturdy installation that still permits ESC to be removed if necessary.

Will this ESC handle the HiVoltage lipo batterys the ones that are rated to 4.35 volts per cell?
Yes, but HV cells are generally only used in cars and this is an aircraft ESC.

Can this ESC handle an 8s battery?
No, these are rated to a maximum of 6S.

Hey John will this esc handle the Hobbystar 4274 motor? I have a slightly less powerful motor that I would use with it if it could handle the 4274
No, these are for aircraft only and will not work at all for a car.
