Didn't look that big in the video! Wow thats a lot bigger!

I've got a pre-order in on one right now, but I'm not sure if I will follow through with it and actually buy one.

They don't advertise it as a crawler, just an extreme conditions monster truck. Those tires don't look like they'd be too bad, and I definitely like the wheels. The brushed motor will keep things smooth and cheap, you can get a sensored BL crawler setup if you wanted more power but that'll cost you. The 4 channel radio is nice, other than the switch for the diffs (looks like a cheap RadioShack switch to me). I'm definitely worried about durability. The new shafts should hold up better than the old ones, but you're putting a lot of stress on them with a setup like that. The remote-locking diffs is really the defining point of these things though. This is the only RTR that I know of that comes with them and it will help a lot when the going gets rough. Too bad they insist on keeping their diff design, go with a 1/8th style diff (6-8 spiders including outputs, tough plastic, big screws, etc.). I sold my Revo because there were too many weaknesses, weak diffs were the biggest issue for me. Those battery bays are also too small to be running a big lipo...the more I think about it the more I think I should cancel my order :bad:

Wow, that thing is going to be huge

Based in the tire comparison that looks to be accurate. The Summit tires are stated to be 7 inch which is 1 inch more than the talons.

The summit tires look like the Tmaxx 3.3 tires, they are about the same size. I think the pic is close enough to see that its really bigger

I like the comparison shot. The tmaxx tires are 6.3". If these are 7" then they are truley bigger. I have wanted to build something this big for a while. I will probably be getting one.

Anyone check out the new driveshafts on this thing. They looks nice. Dual CVD style joints. Claiming to be stronger than the older revo style shafts. Looks like a worthy upgrade for the revo when they become available.

That was the first thing I asked about. :lol:

I was worried that they may be longer than the standard driveshafts bacause it looks that the summit is using the LT rockers and i didnt see them stretching out in the pics. But a TRX employee said that they are interchangable with the e-revo series. Also that the new brushless e-revo will have them.

I like it. I like it a lot. (Had to, sorry. :smile:)

Lots of people are saying that the Revo platform won't work well for a crawler. The way I see it, you would think a chassis with independent suspension would be more capable since the diffs aren't in the way (As they are with solid axles). Those locking diffs only add to the capabilities. It does look like it would benefit from a longer wheelbase due to the larger tires. I think I'll be buying one at some point. :yes:

Having done some crawling with different vehicles in RL, I can speak with a little (very limited) experience on independent suspension vs. solid axle. I've only personally crawled in a SA 1980 Jeep cj-7 (lifted, 33" tires, custom leaf springs), and a few older Jeeps. When one wheel gets in the air the solid axle actually forces the other wheel on the ground & holds traction. You don't need to work the brakes in strange ways, just a slight drag break, and you keep on moving. (well, the second time it happens to you that's what happens. The first time you about piss your pants, and screw it up, then someone pulls you out with a winch, and you fix the body work. ahem)

The few times I saw someone with IS suspension out there, if they got a wheel in the air the other had trouble maintaining torque, they'd use traction control and jimmy with their throttle & break trying to double pedal the hell out of it and work through the same spots. (lots of winches involved, and usually some wood planking to help them drive out)

I think the idea's cool for the summit, but it isn't a crawler (and traxxas hasn't said it is, really). If I hadn't bought an e-revo in june, I'd be signing up for a summit now. It does have some amazing suspension travel, but what differentiates it from a crawler is what would happen when you reach past the limits of that travel, and notice the video never shows that (one wheel totally in the air, slow crawl speed, with any sort of precision). Still fun? yeah, I think it would be as a basher.

Just watched a video on the main page of rccaraction.com. They interviewed a Traxxas employee about the Summit and said it should be available in hobby shops in December.

I just had the best idea ever IMO. What do you think if some took a summit, and made a e slayer out of it? now, I understand there different lengths and all but seriously. locking diffs, lights, you know, the works. Stuffed in a scale package = awesome!:gasp:

Q. Why is everyone saying the summit is 'big' compared to the Erevo? It is an Erevo, with the suspension jacked up- its no wider or longer. The tall shell makes it look larger, but its still got the same chassis and suspension parts as the Erevo. Stick a Clod or TXT-1 side by side with it, then try & tell me the Summit is big....

I'm not saying the Summit is "big" compared to the E-REVO. Their the same size, but a Slayer is not the same size as the E-REVO, it's a whole inch shorter. you do the math.

traxxas employee said that "suspension arms are longer"

If you are referring to the same info i saw, he was referring to the extended wheel base arms, which are currently an option for the Revo.

I am curious though if the arms are going to be different. The bulkheads have likely changed to fit the new diff, so they must have had to re-engineer that interface also. Maybe these new bulkheads will make it easier to fit the 1/8 diff's in it now....Linc, get ready.....

Que?

What has the slayer got to do with anything? The slayer has a completely different chassis to the nitro revos, so yeah, its going to be a different size ofcourse.

Its just that comparsion picture that lots of people are cooing over:

if you jack up the Erevo and add P2 rockers, it looks pretty much identical; it just looks bigger due to the larger shell and big tyres. If I jacked up my Gmaxx, it would be even bigger than both of those still... thats all I ment by its not actually 'bigger'. Its all an illusion....

I was under the impression you were replying to my other post:

The only reason the summit looks "big" in the picture is due to the use of the long travel rockers and installing the pushrods on the innermost holes on the arms. P2 rockers are 90mm while the LT rockers are 120mm. I have both rockers on hand for comparison.

Plus of course, the bigger tires used on the summit.

No worries Modding_out. A proper scale trail truck like the Tamiya F350 type machines you see would be very nice- the summit shell isnt to my taste, but something along those lines would work well with the correct wheels and tyres.

I'd rather buy a Tamiya Land Cruiser CR-01 for $242 instead of this e-revo clone.

Hmmmmm, I think I remember my wife telling me to go ahead and buy the Land cruiser when we went to the hobby shop last weekend. I wish the value of the Japanese Yen drops against the dollar so I can get it cheaper:lol:.

Comparing body post, i think is the same separation or thereabouts.

yeah those are big tires!:lol:

My thoughts exactly. The new diff looks a bit wider and the diff case must be a bit bigger to fit the diff and the actuator arm in there, which appears to be bearing supported. Those bearing would most likely be the 8mm od bearings, and will take up some space. I will most likely pick up the summit (as long as the price is ok) and see if the lst diff cases will fit in there. That would make it easy, lst diffs are chaep on ebay and the bulks are about 6-8 bucks for a pair for the std revo (IIRC) so the summit ones will not be much different in price...

RPP has them listed for preorder at 479

Prices are looking reasonable.

Traxxas doesn't call the Summit a crawler, it is more of a wicked expensive tiny ATV.

It does look like traxxas put a 1/2 in offset into the summits rims (so it would be an inch wider) But I have aready done that to my e-revo. I just wish traxxas would put that 1/2 offset into all there rims b/c a truck thats 23inchs long needs to be wider than 16 inches

wow, that thing really does sit up high dont it!

i may get it in a year. Really depends how much money i have to throw around

If it came with the same 2.4ghz radio and the mmm and motor the brushless erevo had it would be an awesome basher!

if that were the case if it really did come with the MMM combo.....those tiny servos that lock the diffs would definitely be the first thing to go along with the locking mechanism....maybe they'll have the a-arms/drive shafts/wheels to transform the e-revo into summit specs.....

imo the summit is sooo cool! i am pretty sure this truck is going to sell like crazy. nice compromise, nice features, nice look, nice compatibility with already existing parts for the revo. all the talking about crawling is misleading imo. on the page it says it is an "extreme terrain monster truck". and yeah exactly thats what it is. i would prefer "all terrain truck". but i see the the appeal in the word "extreme". lool

nice christmas present.

I think that at 4s or 5s the steel lockers would probably do just fine, and just like a real rig you shouldn't be slamming the lockers in at anything more than a slow crawl....

Exactly, but I can see lots of little kids trying to lock the diffs at speed, which is where the issues will start...

True, but money isn't an object when a kid's dad buys them a Summit anyway...

You never know, traxxas may have an optidrive setup so that the locks cannot be accessed until the truck is not moving. The trans case has a provision to mount the optidrive sensor...

this would come inhandy as a center diff for bashers.... where your bottomed out on a rock, rear tires are down but fronts are in the air ballooning as you desperately try to get traction

i wonder if hardcore 2.2 crawlers can use this sort of system in their rigs?....i know they already have dig-setups or dig-setup ready transmission but this may be another option....i guess we won't know until we see the exact specs on these things.....

Crawlers can't take advantage of lockable diffs in the front and rear, because they are going too slow.
Putting this sort of thing in the center would allow it to be used as part of a dig setup that would require some tweaking.

dude i've got arb air activated lockers front and rear on my truck with over 900ftlbs of torque,

its not a kids toy, maybe a child that would flip that switch while driving shouldnt have that toy

I think it all just depends on how strong they make these lockers. 4wd on pavement is not ideal on a real rig, yet we do it all the time with our 4 wheel drive MT's. I dont think locking at full speed will be an issue and I hope they design it knowing people are going to do it.

Sure, I had a 600+hp twin turbo SBC in a lifted truck on 35s and no problems from the Detroits, but we are talking scale here. Imagine if your truck accelerated as fast as some of these MTs do. If you scale the speeds, acceleration and weight up to 1:1 they would obliterate our real trucks. That said, could our real diffs and driveline handle that kind of torture? The simple and correct answer is no. I don't believe these drivelines(Summit) will handle any more power than they already have, meaning brushless is out of the question. And I will bet that that two speed isn't going to hold up even to the 775 motor. The gearing is just too low. Unless its a metal geared tranny, I think they will fail. This truck as a whole is a failure on Traxxas' part, but with some real crawler upgrades could become a worthy truck.
