Bec and gyro setup

Do I need to power this up with 12s? Thanks guys. Tony Administrator Staff member. If you are going to use the gov in the Castle, you don't need the rpm sensor wire. I don't know if you can put power through the bind port or not. Best thing to do there is to connect power to the receiver and see if you have power between the center and bottom pins on that plug. If you do, then you can run power there. If not, I would not risk it. I'm sure the dual leads is for current capacity.

I will bet if you use a continuity tester, the red and black wires on those two leads coming out of the BEC will be connected.

If they are, then you can get away with running one as long as you are not pulling too many amps. Set the BEC up first, you need power to set up the ESC when you calibrate the throttle and you are likely going to have to use sticks on the Tx for the rest unless you can use the Castle link on that ESC. To use one battery, just make a jumper for one of the plugs to connect the two pins. Just make sure which one is positive and which one is negative.

If you connect it up backwards, the magic smoke comes out. Cool , that solves one problem by providing me with an extra slot and removing my bind plug concern. Yes it is for current capacity your right according the manual they are to split for that purpose.

Going to use the Castle link for both. Here is the worry Tony. These are the things I stare at, check and double check.. Im a wood guy prefer a router or table saw to a soldering iron So straight plug in black to red , no issue. In order to set up with only one battery,am I building a 2 connectors down to 1 connector jumper for the battery end of this diagram? Respecting the connection on the ESC side two plugs I would then need to link the 2 black wires together on the battery side and the 2 red wires from each connector similarly together resulting in only one connector that my 6s battery would plug into correct?

Sorry Tony, but for the electronics you dont need to dummy it down, but rather stupid it down LOL No magic smoke In that diagram, if that is how you have it wired, you will need to keep the top battery right where it is but you will delete the bottom battery.

Instead, replace the battery with a connector that just jumps the red and black wires together. If you run the wires like that, you will see that the top batteries positive is now going all the way to the ESC rather than into another battery. I'm not at my desk right now, but tomorrow I can do a diagram to show you what I mean if text is not your thing.

I know I have a hard time reading something and understanding it. I like to see it. So if you need that, I will make it tomorrow. Yes please Tony.. I would appreciate the drawing. If you look at the photo of my wires you'll see that it's a copy paste of the manual diagram provided it is just inverted as the red wire in their diagram comes off the left side of the esc and mine is on the right I will see what I can get done in the morning.

These names will be used interchangeably throughout this article. In an electric model, the motor LiPo battery pack is typically between 7. In this case it would drop the 7. Pay close attention to the specs on your unit to be certain it will work with the desired setup and voltage input level. The difference between these two types of voltage regulators is dictated by the method used to provide the end result.

Switching Method. The switching method can be explained in a simplified way by saying the BEC unit acts like a high speed switch constanly turning off and on in order to provide a steady and accurate output voltage.

This method is very efficient and will also be very accurate with varying levels of input voltages. You will find the current and voltage specification in your manual received with the unit. A switching BEC is also found in many stand alone units. Linear Method. They may be similar to 3 amps at 5. What is often not explained is how this actually works in terms of those provided specs.

A Linear BEC works by turning the excess voltage in to heat. So what does that mean? Well, if you plug in a 7. Now what if it were a 3 cell LiPo? The linear BEC must remove about 5. As you increase in cell count, the linear BEC must work harder to remove the unwanted extra voltage.

It is a nice cheap, simple solution that works very well at low voltages like 2S lithium and 6 cell NiCd packs. If you are flying a 2S lithium aircraft, stick with the internal linear BEC on your speed control because it will be cheaper.

Since the external switching BEC will work efficiently at higher voltages you will immediately notice your speed control running cooler. You will be able to run more and more powerful servos.

You will be guaranteeing reliable power to your receiver and servos. If you have ever suddenly lost power to your receiver in flight, then an external switching BEC may be the answer to your problems. Are there any other reasons to get an external BEC? Some of the new Spektrum receivers draw significantly more current than a normal receiver, and are particularly sensitive to voltage fluctuations. An external switching BEC can help ensure your new receiver gets reliably powered.

Our switching BECs also allow you to have a choice of output voltage - 5 volts or 6 volts. I'm not using a speed control. Can I still use the BEC to give me a steady voltage? By all means! Dimension Engineering BECs maintain all their specifications without a speed control attached. One of the great things about an external switching BEC is that it allows you to choose your voltage output.

Running at 5V gives you standard servo response. Running at 6V means more power will be delivered to your servos, so you will get more speed and torque. Running at 5V or 6V will depend on what you are flying, and how you personally like to fly.

A simple parkflyer that isn't doing any complicated maneuvers will probably feel best at 5V. If you are doing complicated 3D aerobatics with sharp turns, you will probably appreciate the response 6V gives you. Helicopter flyers especially like the response 6V gives them on a tail servo.

If you decide you want to run at 6V, make sure your servos can handle it. Most servos can, but some really tiny ones like the Hitec HS will burn up at 6V. How will a switching BEC affect my flight time? Actually, it will barely make a difference to your flight time. Compared to your main motor, your receiver and servos barely draw much power at all.

Nothing really noticeable.
