Badger's Vaterra Twin Hammers 1.9 Rock Racer

[xkill]

I liked the way that the back of the chassi, that has the spare on, flexed away on impact, much better than being rigid and braking.

Thanks Badger to have the patience to reply to all of these questions.
It sure looks like a great RC.

what is the motor on that twinhammers in the video?

Your question is a little vague. You can't run 3s on the standard (stock) setup because the ESC does not support 3s.

Yeah it's impressive. And to think this isn't even the worse it's been through.

hi badger.
thanks for all the info.

can you maybe upload an unedited version of this vid? it could help me and others understand the speed and handling of this rig.
is it metric hardware?

I am working on the full video which will have plenty of full speed shots showing how well it handles.

It's all metric hardware.

I'm like the look of the power it has with that tekin roc motor in there,
Can't wait to see the full speed video

Thanks for all the comment to are answers it is very helpfull

So on average the run time is give or take 20 mins depending on driving style? My question in regards to that, is how long does it take to charge the stock battery after died?

I know a little noob question but I've been out of scene for awhile and know nothing about lipos.

Li-Pos really don't make a difference. Its mAh capacity of the battery and charge rate that determine how long it will take to charge the pack

From the specs...

• Dynamite® 2S 7.4V 2000mAh Li-Po Battery
• Dynamite 1.8-AMP AC Li-Po Wall Charger

It'll take about an hour with the included charger. Maybe a bit over depending on how many mAh you used.

With a better Li-Po capable charger you could charge at a higher amp rate (if the battery will support it) and reduce the time. I'm not sure what the C rating for charging is on the included battery. Maybe badger can answer that.

Most of the Dynamite packs I have seen are rated for 3C charging. Even at 1C on a good charger it should only take 20-30 minutes to charge 2000mah.

A 1C charge rate for a 2000mAh pack is 2A.

It will take about an hour for a charger running at 2A to put 2000mAh into a pack.

At 3C (6A charge rate) it will take about 20 minutes to put that same 2000mAh into the battery.

not sure if this has been asked or not but what gearing are you using with the roc motor?
Any chance the spur would be able to be switched to a 32p spur setup? have only been able to find a 22t 48p 5mm bore pinion lol I plan on using my 3300kv pro4. lol

[northkona]

Amain have a good selection of Robinson 48p 5mm pinions in stock.
Congrats to Randy Slawson 1st finisher 2013 KOH , pity its a live axle rig , there goes a Twammer build of his rig!

[SubyJeff]

so originally i couldn't decide between the twin hammers or the SCX10 jeep wrangler, so i got them both

shoot me a PM if you go out to niles this weekend! I only have one battery so far, the others are on order. and i have to read these threads about "fixing" the twin hammers servo, which is kinda confusing to me since i'm a nooby.

It has been asked, I'm using the stock gearing which works great with the ROC 412.

32p gearing IMO is not needed at all. Even with the awesome power the ROC 412 has and shifting gears at full throttle on 3s I have not had any issues with the 48p spur/pinion gears.

That's freaking awesome! I have two of the stock lipo's that I'm not going to use, you can have them. I'm trying to figure out where to take these on a night run tomorrow night with lights on the rigs. Let me know if your interested.

[razors 33]

I hope someone posts from vids of this unit doing some crawling

Hint hint lol

absolutely! just let me know

Do you think you can make it wider so it can fit more easily a 2.2 set of tires?

I have no idea and honestly don't care to find out because I never plan on running 2.2's. I think they are too big and will just add extra weight and rotating mass that will more then likely break shit.

More slow-mo please

[ESC]

well even though maybe just make it wider for estability?
