Thats what I would do. I run robot servos in my trucks, they can handle higher voltages than the dig servo can. I wire the bec to the steering servo at what ever voltage I want, then use the esc's bec to run the rx, and dig servo. Works very well. Sorry to ruin this thread with some actual tech..... carry on. | |

And how do I wire it? In series or parallel with the engine? Wait, I just confused myself even more... damn it! And I'm even more confused cuz I don't know which X to click? Quote:
Wait, who the fawk are you to ban people from BECs... nevermind. I should kiss up before you ban me and have the BEC police come and confiscate it from my crawler. My crawler worked just fine with the stock RTR electronics. As I started upgrading stuff, better servo, dig with second servo, etc. I started having glitching problems, so I got a BEC, and the glitching is gone. The OP is sort of right. But only sort of. Here's the correct answer: A BEC allows your RC (insert whatever truck or whatever) to direct up to 5 (or 10 with the pro) amps of current from your batteries to your auxillary components, without using the internal BEC on your ESC. If your existing components aren't receiving enough current, then you SHOULD get a BEC to prevent having to replace expensive components later when the magic smoke escapes, and you'll likely have an overall better experience with your rig. How do you know you need more current? Well, when your auxillary components start "glitching" or "cutting out" then they are likely not receiving enough current. Also, when you start to notice your crawler having issues like that, and you order a BEC, send trucknuts a PM and tell him that he was right. If you have a BEC, and it works, send him a PM and tell him how much you appreciate his Tech thread about how much we need one. He needs the attention so make sure you send those PMs often. | ||

Thats what I thought, I wasn't sure if that would give me better performance since I would be giving a dedicated internal 5 amps to the 2 micro's and the external 10 amps to the steering rather than all 3 servo's sharing external 10 amps...... Am I off base with this? Thanks. |

I used to run everything with the bec, till I got the losi. The available amp draw was eating the dig servos up real quick. Once I isolated the bec to the servo and ran the dig off of the weaker bec in the esc the dig servos no longer burn up. | |

| That's how I have mine, bec - steering servo, isolated from ESC, which supplies power to the rx then to the dig servo. dig servo has no issues at all.

Well it's actually for a crappy tp mg946r thats maybe 220oz(intentions to upgrade soon) My dig servo is a hitec hs225mg thats about 65oz and the remote diff lock in a micro venom servo that can't be much more than 9g all off a Rooster crawler. |

And trust me, spending money on a good servo is totally worth it. I went through 4 TP's before I called it quits and bit the bullet on a big Hi-tec. Don't know why I waited so long. | |
