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...

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.

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


yeah those are big tires!

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.

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

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.

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.....

[RideIcon]

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....

[suicideneil]

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

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...

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

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.
