Hello everyone. I have a question about changing out my steering servos to a higher torque or possibly just adding BEC's to help regulate the voltage going to them to insure i always have the correct power going to them all times. I'm kind of new to the RC thing i guess ynou could say. So my real question is here, do you need (1) BEC for each servo since most BEC's i'm seeing online are rated for 6v or so?

Thanks, Jason

1 bec will work fine for all the servos in the summit.. but the built in bec on the evx2(I assume is in your summit) puts out 6v @ 2.5amps (standard servo voltage is 4.8v-6.0v)so you should be fine unless your having some kinda glitching when your steering at full throttle. If you are having glitching some thing like a Glitch Buster Capacitor might help

The dual servos that come stock in the summit should be strong enough, but they are plastic gears... To upgrade them is a good choice. Make sure to upgrade to metal gear servos that have a combined strength more then 250 oz.-in, so basically make sure that each servo has over 125 oz.-in and a Transit time faster then 0.17 sec/60° @6.0v (that is the combined stock servo strength and speed in the summit) also make sure that both servos are the exact same as each other and also get traxxas part #5344X Servo saver spring, heavy duty (for use with metal-gear servos)

I don't think if you up grade servo's you will need a bec. I would upgrade the servos FIRST. Then if your having a problem MAYBE some thing like a bec or glitch buster but I highly doubt you will need anything like that.

I hope this helps for the price and specs these seem like a good buy, but it never hurts to ask around..

One of these has more torque than the 2 stock servos combined in the summit and is even faster. so you could just get away with just one of these servos...

I somewhat understand what you are telling me here. Like i said i'm new to all this so it's all a learning experiance to me. I have done some reading on the BEC and thought it was a good idea. I guess the crawler guys like them to make sure they maintain full power to their steering servos. I was thinking also about upgrading to maybe a Hitec high torque servo. I just wasn't sure if my reciever could handle it and if i did that would i need a BEC. I'm lost when it comes to all this.

I dont think for just bashing around you would need a bec. What hitec servo or servos are you planning on upgrading to?

Probably talking about the hitec hs-645mg which is a proven awesome servo but a little slow. I also will be trying the savox here soon for my Savage. Bec should not be needed as stated above.

this here is what i'm looking at now. The Hitec hs-7950th

With that servo only one is needed. I use Hitech only and they are really good servos and the customer service is one of the best. Go with the one you want. Do the single steering mod and your set.

So here's now my next question. If i want to go brushless do i need to do any gear changes? I've been looking into it and i see several people talk about the Tekin RX8 combo motor and ESC. Will it work perfectly or would i need to do some modifications. I'm not really a speed person, but it's nice to know i have it and can use it if needed. Also if anyone knows about that combo is that Tekin motor just as powerfull if not more than the Titan 775?

Yea, any large scale brushless combo would be much stronger than the Titan 775. Tekin RX8, Castle Mamba Monster Maxx, HPI Blur/Tork, Xerun 150A 2000kv combo, or if your on a tight budget the Xerun 80A 2200kv would be a nice upgrade. But I ditched the dual 2075's in my Revo Brushless Edition and grabbed up a JR z9000t (digital, 330oz/in) and it was a worthy upgrade. Faster more responsive steering and more torque. Just make shure you get above 250oz/in..
But brushless is well worth the money. No motor replacement and from what ive seen the 775 isnt the cheapest stock motor out there. Longer run times as well.

Thanks, but what I'm most concerned about is if I go brushless do I need to change the gearing at all or will it just bolt right on and be ready to go?

Stock gearing works great. With the brushless motor and 4s (2x 2s 5000mah) lipo power, the top speed in high gear is very impressive. The torque in low is what I would call tree stump puller strong. The sensored setup is the way to go. No cogging issues at crawling speeds and it is super smooth throughout the RPM range.

Greetings,
I am new with the brushless set up, appreciate if you guys can help me out....
When you guys mentioned about power to run the E-Revo or the Summit did you guys mean the ESC need to be more than 80A and a motor of 2200kv.

Can I do with an 80A ESC with the vxl 3s motor which is at 3500kv?

Can I run an E-Revo on a vxl 3s waterproof esc & motor...thanks

Same Summit as mine. Well it was white anyhow. So i guess that answers my question. I think i'll be doing the Tekin RX8 setup then.

Thanks, Jason

The VXL system is to small for the Summit. It would run it, but not very fast and it would have a short life in there. The Xerun 80A would be just fine. I run it in my Maxx with a 2200kv and Ive ran the ESC in my Revo before now. You'll need something bigger motor wise. The VXL motor is only a 3650(36mm wide X 50mm long) You'll need something with a 5mm shaft a linger can. Somwthing like 3665, 3674, 44"" and so on.
Heres a few buget motors that would do the trick

If I were to use the normal 80A ESC, how do I waterproof it...will the electric motor & battery connector gets short circuited...when run thru mud n water...

Planning to run my E-Revo on 40series Moab tires, what wld be the correct gearing configuration and battery set up..

Another thing about brushless motor that bothers me...what is sensored n non sensored motor...where does it applies...thanks guys, really appreciate the info.
