Hi MSH-Team,

I am new to FBL Systems as I have flown flybar helis only till now.

Now I got a Goblin 570 and right now setting it up.

 

My question is - how should I connect the BEC wires from ESC?

  1. Throttle signal wire and BEC (C)
    1. connect to Brain or
    2. connect to receiver
  2. 2nd BEC wire (B)
    1. connect to Brain in case (C) is connected to receiver?
    2. connect to receiver in case (C) is connected to Brain
    3. do not connect anywhere because of short circuit risk

 

Here the connections info of the ESC:

I hope you can help me - I do not want to create a short circuit and damage MY Brain 😉

 

Thanks in advance,

Stefan

It depends if you are using a receiver with serial output protocol on a single wire or a standard receiver and you are using the various PWM outputs of the various channels connected to the various inputs of Brain2, information that unfortunately you did not give us and that we can not even get without receiving the configuration file.

As with the HobbyWing ESCs (from which they derive), also with the Align ESCs it is convenient to unify the secondary connection of the BEC (B) with the RPM signal (A) by removing the contact from the plastic connector A and inserting the contact A in the free space of the connector B. This cable (B+A) should then be inserted into the "GOV" connector of Brain2 so you have the secondary power supply and RPMs connected to Brain2 which can be used even when you do not want to choose to use the Brain2 proactive governor but continue to use the ESC governor.

In on-board avionics, the power consumption of the servos is enormously higher compared to the almost insignificant power consumption of the receivers and the Brain2 fligh control unit. For this reason, it is always better to connect the BEC voltage output connectors near the servo connectors and then on the Brain2 connectors and never on the receiver, which does not require high supply currents.

If you are using the various PWM outputs of a standard receiver then your only option is to connect the C connector to the throttle channel output of the receiver. In this way the BEC current will be transferred to the servos via the various PWM channel cables, but you will never be able to use the proactive Brain2 governor (nor will you have many other functions such as Aux2 secondary output and Auto Level and/or rescue control via an Aux1 channel).
If, on the other hand, you use a single serial protocol output connected to the CH3 input as the receiver's output, then you can / must connect the C connector of your ESC to the CH1 connector of Brain2.

All this is already well documented by the eighty connection diagrams that are displayed in the Wizard's panel n°4 "Connections" depending on the type of unit connected via USB (or via Bluetooth) to the PC and depending on the communication protocol selected in the previous panel n°3 "Receiver Selection (Input)" of the Wizard.

@customercare So im using just 2 DSMX Spectrum Satellite Receivers, so would that mean that i would connect A and B together and then plug it into the GOV port on the FBL?

@customercare So I’m running an Align 550X with the Align RCE-BL100A Brushless ESC. I am wondering how can I make it so I can use the governor to set my head speeds. Because I am currently having issues with my tail floating to the right when I do a hard punch out. And I have tried all sorts of tuning with the PID gains in the Brain, and it seems to not work. 

If someone could help me with this, I would greatly appreciate it! 🙂
