Try 16t first, that would give you enough going out of corners.

I have 17t in my 6.5 Novak.

Default Lipo Batteries ????

I have a brand spankin new XXX-4 G+ on it's way (awesome eBay deal, BTW) and have a few questions about lipos. I am moving the MM/5700 over to the XXX from an SC10 which is going to the new SCT spec. I have a couple of 3250 CoreRC lipo packs that can be used in the XXX as well as the SC10. Are most of you running larger packs, say 5000mah in order to better balance the buggy, or will the 3250s be sufficient? I wouldn't mind a little more run time as well and the price on the SMC 5000 lipos looks good.

Also, what is the steering mod that most are using to get more throw from lock to lock? I glanced over almost every page of this thread and saw it mentioned several times, but never what was actually being done.

I have 4000Mah LiPo's for mine, and I need to add about 4oz of weight to the battery side to make it equal. I would rather have a larger battery and more run time, and less weight to add personally.

i think i pretty much broke the hardest to find part on the face of the earth.
(its not broken but its just seriously weakened to the point where a hard smack just rips the hinge pin right out. i can still drive the car its just that ive had it rip out and bend hinge pins if i take a big hit)

You and me both.... I wonder if you could just have someone that's good at mig/tig welding, just put a small amount of material there and just file it back?
just a thought.

Wow, that's very unfortunate. Any luck with aluminum welding/soldering to build it up a bit?

hi just thought i'd add my 2cents worth

I basicly learnt too drive in my xxx4G+ (never had an rc car till i bought this)
its fitted with a MM 5700

So for a novice it was like trying too steer a bullet once it was fired lol

So of course i quickly found just about every weak point on the car hahaha Ive fitted doubled shock towers front and rear, aluminium outer pivots (an just recently rear inners), aluminium front carriers and the front diff brace mod (using PC board)

After fitting these items and of course learning too drive better ive found the xxx4 G+ too be just as strong if not stronger than the other newer brands of cars. And just as fast if not faster in a club level.

Now my weak link on my car when i crash is my ball cups, i run the standard kit ones, i could upgrade them too the stronger rpm ones but i believe its good too have a cheap easy replacable item as the weak link in a crash rather than an arm etc

Default Well, it's here...

and very happy with the deal. Brand new roller with custom painted body. Just need to get the MM/5700, radio and servo installed. I'm assuming a 16/92 gearing would be a good place to start with this esc/motor set up.

any car has its fragile points . but once you learn how to drive smooth and flow with the track you break less and less

thanks for the idea

i got some steel putty compound and with my fingers i molded a small piece to patch up the cracked part around the edge.. it looks like it will hold pretty well maybe even stronger than it was before...we will see at the next race day

Thanks. It's spent its entire life as a shelf queen. I imagine it won't look like this for long, although I have a new body coming to do a simple paint job on and practice with. This one was professionally done and I can't see tearing it up right away (I spend a lot of time upside down and into the fence).
