E-flite's brushless ESC includes improved BEC capability and programmable voltage cutoff. Programming options such as auto-select E-flite's brushless ESC includes improved BEC capability and programmable voltage cutoff. Programming options such as auto-select cutoff voltage that automatically recognizes LiPo batteries or a Ni-Cd/Ni-MH programmable feature, programmable braking, thermal overloadprotection, advanced software and gold bullet connectors are also included.
Servo Rating Chart
* It is always best to use a fully charged battery pack in order to ensure proper cutoff voltage is selected. Once a battery pack has been partially discharged and unplugged from the ESC, reconnecting it before fully recharging the pack could result in the incorrect voltage cutoff being selected, possibly causing damage to the pack.

** When using economy class sub-micro servos, it is best to reduce the number of servos by one due to the higher average and peak current draw commonly associated with these servos. Also, be sure to position the ESC for maximum airflow since cooling can significantly aid in the performance of the BEC.
If you wish to disable the BEC (required if you’re using more than 10 cells) from the connector, you must first remove the red receiver wire and then insulate it properly to prevent shorting. When the BEC is disabled, you must use a four or five cell receiver pack to power your receiver and servos.
