Manual for VLV F3A ESC

Attention!!

Thank you for using our product. Any Improper operation may cause personal injury or damage to the product and related equipment. This high power system for RC model can be dangerous, we strongly recommend reading the user manual carefully and completely. We will not assume any responsibility for any losses caused by unauthorized modifications to our product. We have the right to change the design, appearance, performance, and usage requirements of the product unannounced.

Rated continual current and burst current are for good heat dissipation. Please mount the ESC behind the air intake (2-5cm).

Please Remove propellers when you do all the ESC set up on your transmitter.  

Main features

● ARM 32-bit Cortex MCU.

● Plug and play for all F3A electrical power systems: motor, single drive, and contra drive.

● Famous brand MOSFET with high performance and low ESR, design for large current.

● Small size, lightweight.

● Regenerative braking, causing very fast motor retardation.

● Arming alarm. The ESC will start beeping if the main batteries are armed and the throttle

signal has been zero for more than 10 seconds.

Transmitter set up

1.     1.     ATV set up. For safety reasons, the input pulse width of this ESC is fixed to 1040us ~1960us, you may need to change the ATV for the throttle (motor) channel, for Futaba, you also need to reverse this channel. Check the normal operation below. PLEASE – REMOVE THE PROPELLERS!!!! Check all connections according to connect diagram, check your Transmitter, make sure your throttle stick is in the low throttle position, then connect the main battery pack, you will hear power-up music (step1). After the power-up music, you will hear one low beep, indicating the throttle signal is detected (step2). Then you will hear a high beep, indicating zero throttles is detected (step 3). If you cannot hear the high beep, increase ATV in the throttle channel on both sides until you hear the high beep, then add another 5% just for safety. After you hear the high beep, the ESC is ready, add throttle your motor will run. Check the direction of your motor, swap 2 motor wires if you need to change the motor direction.

2.      Throttle curves set up. This ESC needs to set at least 2 different throttle curves to suit a normal F3A sequence. (RPM only an example for contra props set up, if you use a single-props motor, you may need a different RPM setting)

·      One curve for normal flight, keep 1500~2000RPM when throttle stick full back (about ¼ of throttle, this point will set your downline speed), 3000~3300RPM when throttle stick in the middle (this point will set your cruise speed for level flight).

·      One curve for landing and spin, keep 100~300RPM when throttle stick full back (keep props spin but no thrust), 3000~3300RPM when throttle stick in the middle (this point will set your cruise speed for level flight).

·      Set a motor kill switch, keep output pulse width less than 1000us when you flick the switch.

·      Set Failsafe for throttle, keep output pulse width less than 1000us when lost signal.

More tips for this ESC

·      Always keep throttle during F3A sequence fly, move your throttle stick smoothly to control your model speed, only go full back throttle on the vertical downline.

·      Set your downline mix Master as throttle stick position, not throttle output, so your downline mix will work well even you have ¼ throttle output minimal in normal fly condition.

·      Because of the powerful brake of this ESC, you need to keep throttle during the landing approach, use the stick continually to control your model speed, only go full back stick when your model touches the ground. If you cut the throttle when your model is still in the air, your model will stall immediately.
