Default Brushless and Lipo for XXX-CR

I'm thinking about getting a XXX-CR and need some recommendations for brushless and lipo batteries.

I was thinking about Novak gtb 6.5 do you recommend something else?

Which lipo should I get? 35C at least?

I want to race 2wd mod.

I use a Trakpower 4900 2S lipo in my XXX-CR. Fits perfect if you reroute the esc wire. The trakpowers are a very good dependable pack to use.

So many different combinations for the buggy.

If running a mod in the buggy, I have thoroughly enjoyed the L series brushless motors that novak came out with. That would be the only way I would attempt to go down to a 6.5 is with an L series motor. If your using a R motor stick with 8.5 or 7.5 based on the C rating of your battery.

As far as batteries go, I just picked up the new Team Orion Lipos that are 3800 with a 30C rating. Plenty of power and makes 17.5's and 13.5's extremely punchy. They are priced fairly well and have solid cases which makes handling and care a dream. The battery casing has slots cut out the bottom to mimic cells so that you can run weight plates on the bottom if need be. Id say if your running club racing dont bother with the weight plates. You can adjust and adapt your setup for a softer suspension and it will handle similar to a car with the added weight.

Hope that helps

I would only run a 6.5 on a really big track or if you're a pro driver. stick with an 8.5 and you'll be plenty fast and more controlled

When you discover that you have way too much motor (6.5, 7.5 even 8.5), unless you are a pro, don't forget you can dial down your endpoint adjustment and your punch control and it will become driveable.
Dial back up to suit your ability.
I've got a 5.5 in my 4wd and it was stupid fast but with it dialed down to about 75% it is just about sane.

Indoor track 10.5-8.5

outdoor track 8.5-7.5

The esc your gonna get mixed reviews.... sphere comp, Losi excelerion, tekin.

The new SMC 5200 24c lipo is a steal at 84.95. If you wanna spend more the SMC 5000 28c is about 119.99.

for mod offroad you don't need a high C battery. they're nice to have in case you want to use it for something else but case in point, last year running mod truck with an 8.5 motor I used both a losi 5000mah 20C pack and their 4400 30C pack. I was more consistant with the 20C pack compared to the 30C pack so my overall times were better but it was easier to pull wheelies with the 30C pack

so 6.5 would be an overkill for 2wd buggy?
what if i turn down the throttle? would there be any disadavantages? are 6.5 brushless motors heavier than 8.5?

Just know this, 6.5 is gonna be really, really fast.
How is your throttle control?
I get away with a turned down epa with the 5.5 motor but that is on a 4w drive that seems to handle really good.
Not sure what your results would be with 6.5 in a 2wd.
I personally chose an 8.5 for my 2wd because when I try mod again I want to have a chance to control it.
I'm running 13.5 geared really high right now and it feels like a mild but strong mod motor. I considered a 10.5 for mod but a deal came up on an 8.5 so I jumped on it but haven't tried it.

I run a 5.5 BL/Lipo on my T4, I turned down the EPA on the radio, and it handles it fine. It's like running an 8.5 BL on the truck.

If you have EPA adjustability on your radio, get the 6.5 and turn it down, once you start getting more control, you turn it up a little at a time

As for packs, having a 20C or 30C really isn't going to matter much, cause your motor is going to be fast, no matter which C rating you use, I would recommend a higher capacity (MAH) pack, since you're going to be running a Mod Buggy, If you were running 10.5 BL -- 17.5 BL, then I would recommend the 30C 3800 Orion Lipo. As for the Mod Motors, 8.5 and below, use the Trakpower 4900 20C lipo, they work great.

That`s a bit vague . Some places have big indoor tracks . Many at my indoor track run 7.5 -6.5 and a few run 5.5 .

I suggest going to your track and ask around what the other buggy drivers are running . They will give you the best answer as none of us have been to your track . Driving style plays a big role as well , if you are a smooth driver you can run a faster motor . Personally , I like the 6.5 because I started with turning it down in my radio and the better I got on the track I would turn it up and so on . I like having the extra power in case I need/want it . As for lipos , there are many great brands , stick with a popular one and you will be fine . I run Orion lipos now and think they are great . 30 C has a lot more punch then a 20 C , which I prefer 30 and can`t wait to try the Maxamps 35 C packs . But to each his own .

Yes. 6.5 is too much for any track, just about any driver. They all weigh about the same. Get a 10.5. If you're new to 2wd mod, you'll find that it's fast enough for just about any condition that you'll encounter with your 2wd. Unless you have a 125+ft straightaway, there's no need for anything more, it'll just cause you to make mistakes. WIth lipo, the car can be run a couple of ounces lighter (you'll probably want to add weight regardless) so you can gear really tall. A 10.5 has a bunch of torque so it'll still have tons of punch.
