How to connect Hobbywin UBEC 10A

[wa1210ck]

So along with the SCX10 III and a Savox SW1212SG, I bought a Hobbywing 1080 ESC and Hobbywing UBEC 10A.

So, first question is do I really need the external UBEC? The 1080 says it can do 7.4v. The servo does some beefy torque at 7.4v. I was told I needed to get an external BEC but I think I can just program the ESC to push out 7.4v...

Second question is IF I need an external BEC, how would I connect the Hobbywing one? For reference I know to connect BEC leads to the battery (either separate or in parallel with existing) and then to the RX (or with an Y-adapter, to the servo then to the RX) but the Hobbywing one has two plugs that is required to plug to the RX. Now I have no more spots available on my RX. So does that mean I cannot use this particular BEC? <-- I have two additional slots I plan to use for lights and a winch so while I do currently have two more slots, I won't in the near future...

Thanks guys!

As for the need for BEC are you using 6.0V micro servos for either or both 2 speed / dig unit? If you are you'll want to set your BEC on the ESC to 6V. If you want to run the steering servo past 6.0V you will want the BEC.

As for your plug situation. You can always get your lights connected with either a battery accessory that you can plug a JST into getting power from standard batteries or you could us PowerShift Technologies setup where you plug your lights into the balance port on your battery. This allows for full 12V lighting and frees up a spot in your receiver.

That's right, I forgot about my micro servos...ok. BEC it is. So I'll set my ESC to 6.0v and then plug the extra two leads in to the RX to get the extra power to the servo.

Thanks!

BAM! Custom RX bypass with two plugs!

Sooooo, the Hobbywing BEC required its own power source and rather than using a separate battery, I decided to build something for myself...so the HB BEC has some tiny-ass wires that took some effort to solder some T-Plugs onto. But once I got that set up, I had to figure out how to get power to it...I'm running a crawler so more weight prob wouldn't be in my best interest so I decided I needed to run the plugs in parallel and soldered up some bullets with XT90 for my ESC and TPlugs for my BEC. Came out pretty good if I do say so myself. Just not the solder on the bullets...

Soldering is a must have skill with these! Nice work. "thumbsup"
