What do you guys think?

Looks good, IMO. I wonder why they took it off, maybe a huge design flaw that had been overseen perhaps?

that looks really cool, is that a motor in the middle a single outrunner or at closer glance it looks like 2 inrunners side by side. Either way I want it

It does sound very good. I'm disappointed with the quality of losi stuff though. I want a crawler but I'm not to sure I would be jumping at a losi one too quickly.

The front and rear dig is cool...

Take a look a the new Venom Creeper coming out. It has some really nice features.

Remote Lockable Diffs and more.

They probably found melamine in it.

Me likey.. I wonder if venom stole traxxas' idea for remote lockable diffs or vice versa.

don't know about the losi, the venom creeper looks cool, so does venoms 1/8 bike

RCCA was supposed to get the first release on friday, but losi kinda screwed that up.

Looks like a sensored inrunner in there to me.

I'm sure you would know better than I, but my thoughts were the same. That pic is just so damn small, it's hard to discern a sensor harness.

Well, I can tell it isn't a brushed motor, and I know that losi wouldn't half ass it and put an outrunner in a fancy can. Can't compete with sensorless really. Didn't sound sensorless in the vid either.

Good thing I am working on a sensored motor that would be lighter and most likely have more power too :D 1000kv inrunners that we normally have too much resistance to make power on 2 or 3 cell lipo.

Yeah, almost willing to bet it is a 21.5 xceleron

I like the truck. Super low CG. I would want 4ws though. And who need remote lockable diffs? Waste of money in a crawler. You want the diffs locked all the time when crawling.

4ws isn't allowed for competition, though, which I'm sure is Losi's target crowd.

...And since you can't have 4ws, being able to unlock the diffs can help you make tighter turns when necessary/possible on the comp courses. It's definitely not a waste of money if you like to win competitions. :-)

You aren't going to gain turning ability on the rocks by unlocking the diff. It will allow you to turn tighter on asphault but how often are they actually making U-turns on a flat surface.

It's a 17.5 turn

look at that 1st pic ..well 2nd in this thread in the original post, look close, there are 2 motors, maybe thats their el delay


maybe not I am cross eyed

Looks like just one, and on RCZone they showed a pic of the mechanical dig. No need for that if it were two motors. I like the worm gears in the axles, mega center clearance.

Looks cool. Probably more money than I feel like spending on something that goes slower than 50 MPH :tongue:

I take it you don't frequent R/C Crawler competitions. It doesn't need to be a flat surface due to the crawler's ability to keep its tires in contact with uneven surfaces. Extremely tight turns are a part of every course I've been on in the three years I've been competing, which is another reason why dig is so valued among us.

Unlocking the diffs won't help in every situation, but there are more than enough to make it a highly valued option as well.

There are many more reasons to have remote lockable diffs than just turning. It gives you many advantages for getting over rough terrain that full time locked diffs cannot offer. Maybe you should spend some time on www.rccrawler.com doing research. Venom did their research on this one and have scored big time.

+1

Here's a quote from Jason on RCCrawler.com, who is one of the pioneers of R/C crawling and knows more about it than I'll ever hope to.

"...the locking diffs will for sure make a huge impact on the rc crawler world, mark my words. The stuff that unlocking your diffs allows you to do is unreal."

He was referring to the Summit, but the point remains the same.

{the silence is deafening}....

Looks alright, and being Bl makes it even cooler. I like the idea of worm gear drives in the axles- thats only something I've seen on custom build rigs before.

Unlocking diffs are awesome. I have one in the front of my 1:1 Jeep (to the left). A locked front end wants to push FORWARD, not turn, due to the tires grabbing at the same speed. An unlocked diff allows the tires to turn at different speeds while the rear tires are locked (DIG) which makes for one hell of a sharp turn. It practically, and in some cases actually does, turn the rig around on a dime.

This is great news. Specially for what I got coming. Mr. johnrobholmes did you get my last message?

Yeah, thats obvious. Any street driven truck will need to be able to unlock to turn. The most successful crawlers(1/1) are locked front and rear. Unlocking them causes traction loss and tire spin, neither of which you want when your crawling. How many guys out there are crawling with open diffs? Thats a serious question. Anyone crawl with open diffs?

So are you trying to say you have more experience and crawling know how than Jason? I really think you need to speak from experience rather than arrogance. When you start winning national crawling competitions I will pay attention to your opinion on crawlers.

I think that you're not understanding what gtxracer meant by "unlocking diffs". He means that he can lock or unlock them depending on the situation. Your statement makes it sound like you think he has them unlocked all the time.

No-one crawls with open diffs all the time because locked diffs are absolutely necessary most of the time.

However, some of the time the ability to remotely unlock one or both diffs would be a huge advantage.

When I start seeing comp crawlers winning with selectable lockers, I may buy into the idea. I think its an okay idea on a basher that sees slow off-roading and on-road speed runs but a crawler is going to want all tires pulling all the time. We'll see, I could be wrong.

Tempted - How many crawlers, RC or 1:1, have you had? Just wondering.

I think you'd be surprised how that feature comes into play. Drive a locked rig and a rig with selectable lockers. You'll see.

Being able to remotely unlock the diffs is a cool idea, that is for sure

My only issue with the losi setup is that the worm drive axles will not allow the free wheel function that most dig setups allow. It is nice when making a steep crawl, or going up a rock that has an indent at the bottom. Not having drive to the rear wheels can help the truck not experience the rear axle trying to "drive under" the truck. However it is important in this situation to let the axle freewheel, as any resistance may cause issues with the front axle pulling the truck up and over. Only way I can see to do this would be to have a slightly slower ratio gear that could be selected to drive the rear wheels slower than the front. No "drive under" that way, and the rear wheels would still turn, helping the front wheels out. Not sure what kind of setup that would require...complex to say the least. Could be done with a clod/worm axle hybrid that had 2 motors and escs. Have some sort of radio mix that had a bunch of expo on the rear esc throttle to drive the motor slower... I really want to make some worm axles with outrunners mounted directly to the worm... Ultra low cg and a very narrow chassis, with super drag brakes and no driveshafts, plus only 2 gears. Its in my head, just need to make it!

The Worm axles will give great drag brake, and having selectable front and rear engagement is a cool feature. I only play crawl, so no reverse points for me. Should be a big hit with the comp crowd, and most likely much cheaper than the kyosho...

A guy in Oregon makes worm drive with outrunners on them, a worm drive clod of sorts. They are $400 for a set of axles, but super nice full metal.


Open diffs really help in some situations. Locked diffs are really only needed when a wheel lifts off the ground. If all wheels maintain traction then turning is much tighter with at least a front open diff. Just like having dig, a selectable diff is very useful and makes the rig more maneuverable. If I had to choose one option, I would go for dig first probably. But if I had the choice I would take a remote front diff locker and front dig too. Now we are talking about 4 channel radios.


Losi really hit a home run with this one, it looks pretty dang awesome all around.

Two 1/1 crawlers FTR. My all purpose truck that I used as a crawler was a Detroit locked 14 bolt rear and full spooled Dana 44HD front. Almost every single time I went off-road I locked the front hubs for a completely locked front end. And every time I crawled I locked the diffs. Bar none. I went places I could never go with an open front diff and I never had to unlock my front to get somewhere. I crawled with people who had open diffs and had to winch them out half the time. If you are making a U-turn on asphault then sure, unlock a diff. Otherwise its a feature that will never be used on a true comp crawler.

Sure it will. Sounds like you haven't competed before. Gates are set up so tight that you have to turn 180's between them sometimes. Let us say there is a gate facing downhill, with the next gate set up so that you must turn a 180 in a 4 foot circle and go back up the same way you came. An unlocked rig could do this pretty easy without a reverse, a locked rig could not. A rig with front dig won't have any advantage, as the dig will just make the front end slide further downhill.


Big difference between crawling and competing. You can reverse with no penalty when just crawling.

Thats true. Like I mentioned, if you have to do a U-Turn on asphault then sure it would work. If your turning on dirt, or any other loose surface, the inside tire will spin. By blipping the throttle you can usually pick the inside wheel up and turn on a dime. Just my experience.

They are called ROCK crawlers for a reason, :lol:

Wow looks really nice.:yes:
