What is a BEC? Do you need one for your servo?

RC has come so far in 4 years. I just picked up the Traxxas BEC kit for my TRX4. Glad I watched this video. I still enjoy your videos to this day. Cheers

Best RC channel, period. Francis you Rock Bro!

Awesomely useful and informative channel you've created. Congrats and thank you. Videos like yours really help with expanding ones comfort zone by reducing the fear and uncertainty of learning while doing. 😁👍

I should've seen this before I stuck in a new servo. I blew up the xl5-hv ESC and had a runaway with the TRX6. Good news is that the TRX6 now has a QR pro 2300 kv and it transforms this rig entirely.

So is the castle BEC capable of having a voltage for the receiver and different voltage for the servo? Or does the voltage for both need to be the same? So if my receiver takes 7.4v and my servo takes 6, I need an additional BEC to just power one.

You make a lot of useful videos, thanks mate!

If I change my motor and esc to brushless would I also need to change my steering servo or could I run the stock brushed servo on my brushless esc?

I heard that the bec from the e-revo fits better on a trx4, if u dont run stock esc and engine...?👍

Hello from malaysia... thanks for make a good video..verry helpfull...for newbies like me..ty

Is that a lead weight on the front of your frame?

Hi Francis.... I knew I had seen you before :-) MTBR of course ... you are doing great there too ;-)

Hey. I am thinking of getting the trx4 kit, the 1 thing that I don't understand I'd the Bec, the castle your reviewing in this video seems to complicated (needing IBM laptop ,or £50 dongle!!), the part at the end of this video is quite vague ,about the traxxas 2260 Bec, you said you were going to do a video on it but i can't find it ,hmm. Anyway can the 2260 replace the castle and is it less complicated?. Love your vids btw. I've learnt a lot ( apart from Bec lol)

So are there any esc that I can buy these days that will give the servo a lot more power? When I get a new esc will I have to change anything else out so it will work right? Sorry for all the questions but I am new to the crawler rc world and I just got a redcat gen 8 and the servo is trash on it lol but I really don’t want to have to try and wire up a bec cuz I don’t know how to. I have also heard that when people put stronger servos on the gen 8 it breaks something on the suspension so if any of you rc guys see this can you please help me out by answering these questions it would be much appreciated

Can the Traxxas BEC fit the Traxxas Stampede 4x4?

Hello, I enjoy and learn from your videos. My question is do you think you have to take into account amp draw from various servos? Say you put this tra2262 into various Traxxas vehicles and put various high torque servos like a Savox in. Do you just focus on correct voltage or do you think theres servos that can draw too much amperage for it. I'm trying to upgrade my E Revo and Summit trucks steering and wondering if I can use the 2262. Can you run 2 servos on 6v? Thanks

Putting a reefs 555 in my gladiator would you recommend a bec? I’m using 3s with he hobbywing esc and a Holmes hobby 27t motor

So I installed a 20kg steering servo on my trx4 sport without the bec and had no issues. Then I installed the traxxas bec and now I’m having glitching issues where throttle and steering independently and or simultaneously cut out. It was like there was transmitter interference, I got up to retrieve the truck and each time it would carry on like no big deal. From 5ft away I’d turn the wheels one direction, let off, and the wheels would stay pointing that direction then correct themselves 5 seconds later and go back to normal. When it’s working correctly, it doesn’t seem that much better than the factory steering servo. It’s better but idk if it’s worth the inconsistent headache. BEC to channel 2, plugged that to BEC, then the 2 prong over to the ESC. Seems pretty cut and dry, idk how I could mess it up if I did 🤷🏼‍♂️

Good info!

HELLO Francis … I need a BEC with multiple different voltage outputs because I need to power 6v, 8v and 11v at the same time and still have a clean setup. I’m looking at the HOBBYWING 10A BEC with 6v/7.4v/8v “Adjustable” but it’s with a jumper… I’m waiting for replies on if you MUST use the jumper and choose only one voltage or if I can use the terminals individually to power 2 or 3 different accessories with different voltage values at the same time. Do you know more about that BEC? Can you recommend me a BEC that will do what I need? Thanks plz reply😎

I purchased a 20kg steering servo like the one you installed in the Bronco in a previous video. I can't find any current draw info for this servo, Will I need a external BEC ? It says in the specs that it produces 20kg of torque at 6 volts.
