Tech Notes

Servo Ratings with BEC Enabled:

Drives up to 5 analog or 4 digital sub-micro-sized servos with the BEC on any recommended input voltage.
Some servo combinations we have tested in various models include:

• 1 analog standard servo, 1 digital sub-micro servo, 2 analog sub-micro servos—E-flite Apprentice 15e RTF
• 2 ParkZone (PKZ1081) analog sub-micro servos and 2 ParkZone (PKZ1090) digital metal gear sub-micro servos—ParkZone T-28 Trojan RTF & F4U Corsair RTF

Some other brands and models of servos may have significantly higher current draw. Digital servos and binding servos of any kind typically have higher current draw. As a general rule, micro and sub-micro servos draw less current which may affect your servo usage as shown in the examples above. We recommend the use of a Hangar 9 Servo and Receiver Current Meter (HAN172), installed between the throttle lead of the ESC and receiver, to confirm current draw of the actual servos used. Also, always
be sure to position the ESC for maximum airflow since cooling can significantly aid in the performance of the BEC.

Before first use, please refer to “Servo Ratings with BEC Enabled” notes for BEC usage guidelines. You must follow these guidelines for safe operation. If you are using more than 5 analog sub-micro-sized servos, more than 4 digital sub-micro-sized servos, or servos with higher current draw than the BEC can deliver, you will need to disable the BEC. If you wish to disable the BEC, you must remove the red receiver wire lead and connector from the receiver lead housing, and then insulate it properly to prevent shorting. When operating with the BEC disabled, E-flite recommends the use of a separate, high-power, external BEC (like the Ultimate BEC), or receiver pack and switch using the following items to ensure trouble-free operation:

1. JR 1100mAh 4.8V Ni-MH receiver battery (JRPB4240),
or similar
2. JR Switch Harness (JRPA003), or similar
