Tech Notes
Servo Ratings with BEC Enabled:
Drives up to 7 analog or 6 digital standard-sized servos with the BEC on any recommended input voltage. This also includes up to 7 standard analog or 5 standard digital and 1 retract servo, perfect for Hangar 9 60-sized warbird conversions.
Some servo combinations we have tested in various models include:
- 6 JR 537 (JRPS537) analog standard servos—Hangar 9 Ultra Stick 40 ARF
- 5 JR DS811 (JRPS811)/JR DS821 (JRPS821) digital standard servos—Seagull Harrier 46 3D
- 4 JR DS811 (JRPS811)/JR DS821 (JRPS821) digital standard servos and 1 JR 791 (JRPS791) retract servo—Hangar 9 60-sized warbirds
- 5 JR DS811 (JRPS811)/JR DS821 (JRPS821) digital standard servos and 1 JR 791 (JRPS791) retract servo—Hangar 9 Spitfire 60
- 4 JR SPORT MN48 (JSP20040) analog mini servos— E-flite Diamante 25e ARF
- 4 JR DS3421 (JRPSDS3421) digital mini servos—E-flite Eratix 3D 25e ARF
- 7 JR MC35 (JSP20030) analog micro servos and 1 JR RT88 (JSP20080) retract servo—25-sized warbird
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, mini and 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 7 analog standard servos, more than 6 digital standard 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 or a receiver pack and switch using the following items to ensure trouble-free operation:
1. JR 1650mAh 4.8V Ni-MH receiver battery (JRPB5000),
or similar
2. JR Switch Harness (JRPA003), or similar
Important Product Bulletin
Programming Menu 7 Instructions Correction
Some instructions sheets included with these ESCs had some incorrect information under Programming Menu 7, #2, a & b. The corrected instructions are listed below. We inadvertantly listed as 8kHz PWM Frequency instead of Normal Mode in 'a' and 16kHz PWM Frequency instead of Heli Mode in 'b'.
Programming Menu 7 – Operating Mode
The default setting is set to Normal (airplane) Mode, which is limited to a start-up rate of 0.25 or 1 second. Alternatively, the Heli Mode can be selected which reduces the start-up rate to 5-seconds for the first start-up and any start-up after the motor/ESC has been stopped for more than 5 seconds. This helps to prevent damaging the motor, gears or any other components from an abrupt start-up when none of the parts are moving. Any time the motor/ESC has been stopped for less than 5 seconds in Heli Mode, the start-up will be immediate. This allows power to be applied immediately, such as when aborting an auto-rotation attempt or for any other reason, to help prevent a crash. Remember, you must wait more than 5 seconds after stopping the motor/ESC in order for the 5 second start-up to occur again.
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 7 times, indicating you are now in Menu 7.
2. Move the throttle stick to full throttle (>1.7ms) position to make changes to the Operating Mode programming.
a. To select Normal Mode – You will hear 1 short beep. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the next selection.
b. To select Heli Mode – You will hear 2 short beeps. Move the throttle stick to center (between 1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave in full throttle for 5 seconds to advance to the first selection again.
