20 mph

[murph12]

I was informed by Traxxas that the Summit will only do 20 mph in high gear on 7-cells. I know its not built for speed, but I was at least hoping it would go around 25 for some good bashing. Low gear it does around 8.

[bud009m]

id b happy with that. can always regear it.

[MR. Clean]

well, its probably geared for torque, hence an all terain monster truck ( ) but if its too slow, vxl it.

[Greatscott]

Perfect for a rock racer!

[need4speed]

sounds about right, i will definately be getting one of these

[Garbage_Man]

Does anyone recall the stock emaxx speed are they comparable?

[tedo]

This truck is not built for speed. It is built for low gearing. Perfect trail truck, winter basher and mud-bogger. If you are looking for speed get another truck / car.

The emaxx was around 24-30mph depending on batteries.

[Garbage_Man]

So we're close though in speed. So with good batts and better electronics it could be a decent competitor I assume. Not that you need 60mph but a decent 40-45 is respected.

Not sure if you could hit 40-45 with the gearing ratio in the stock Summit. I could be wrong. You could change the ratios, add a nice brushless system, but then you might as well get the new bl revo. IMO, the Summit is not a speed demon, rather a basher with gobbs of torque.

I have my bl race revo for speed and the track. Give me a Summit so I can drive it on all the mountain bike trails (and off trail) and slushy parking lots this winter.

[vxlrocket]

if memory serves me right... maxamps has a lipo combo that claims 40+mph with dual 3S....that's about as fast as a nitro buggy.

i think the summit is gonna be awsome. i'm gonna get it and drop a neu 1521 or 1527 in it with a 10S esc or an MGM.

[SnoopMaxx]

My Rock racer VXL will hit 21mph
And my old E-Maxx can reach 28mph

Yea, they have a "guarantee 40mph" but it's not duel 3s, its duel 2s.

[The Oracle]

I think its a good idea on traxxas' part- limit the rpms with gearing, so the diffs will be spared any harsh locking/unlocking attempts at speed. Like has been said before, if one wants a speed machine (35mph+), then jsut buy the Erevo and jack up the suspension, then lower it again as you realise that tall trucks dont do well at high speeds and in the corners. As for dropping some un-goddly 1521 or 1527 in it with 10s lipo, all I can say to that is LOL. Dont be silly....

[Roc]

The traxxas guy in this video: http://uk.youtube.com/watch?v=jG5x3wW41kw says 25mph.. don't know whos right, but hope that helps.

[zoomzoomkid4]

if you put in a 4.5 hv-maxx then when you are crawling the sensors will make it nice and smooth also in 2nd gear it could do some decent speeds 30-35 maybe.

[REDlineRYNO]

is it possible to put in the dual motor plate that comes on the emaxx and run two motors in it, im thinking about doing that

[RustlerRacer16]

You would want to put the dual motor plate that comes with the E-Revo. What two motors would you use? Two Titans? Why?

[REDlineRYNO]

well ill have to see how it performs outta the box, but im planning on making mine a mudder with huge imex tires (shouldnt be a prob cuz the stockers are gigantic) and another motor would just make it more fun with the extra power

[REDlineRYNO]

the part number for that plate is #5690 on buytraxxas.com correct?

[zumiez]

well, its probably geared for torque, hence an all terain monster truck ( ) but if its too slow, vxl it.

that is a really bad idea, the vxl may be fast but there is no torque and it wouldnt work, thats why traxxas didn't make the brushless e-revo vxl, the made it the mamba monster max, so get the monster max if you do go brushless. it has a high cost but it is worth it... look at the e-maxx's on you tube who have it.

[markster]

Kershaw twin 775's

[tomiko8]

The traxxas guy in this video: http://uk.youtube.com/watch?v=jG5x3wW41kw says 25mph.. don't know whos right, but hope that helps.

I like how in that video he says you can lock the diffs without stopping...?

[bashFiend]

well its a 1/8 truck i believe why couldnt you but a mamba monster in it...or something brushless to make it quicker in race mode...i understand you would have to program the esc accordinly for either high or low end but....who knows i myself am getting one and will try out all the different engines..and gear setups...and if it go 20 so be it i will classify it as a rock racer....

[VXL Beast]

I would do a single 700-HO from Kershaw. Now that would be some torque. :P

[noll1]

Is this like a Titan motor that needs to be rebuilt every so often?

[schofield]

how do you rebuild a Titan motor?

[noll1]

I thought the Titan motor was brushed and required replacing the brushes afer so may hours of run time. This is a brushed can in the Summit correct?

[FireWire79]

Correct. You can usually buy a rebuild kit for most brushed motors. As for the Kershaw 700-HO, it should be near the same as the 775 that Traxxas is putting out. Can't say for certain, as the specs for the motor aren't out yet. But when they come out we can get a more specific answer for that.

And I still don't know why you would want to put a brushless system in this truck. It is designed to get wet and dirty. Brushless motors don't like the mud and crud, it is bad for them. I plan on getting the Summit so muddy and nasty every time I take it out that it won't even be funny. Then, I'm going to take the hose to it and rinse it off. Too easy, this is what I have always wanted, climb, go fast, and waterproof.

Used to be you could only get one or another feature, but the Summit gives you both options. I'm so happy. /cry

[Greatscott]

The way I see it, if you want speed, get the E-Maxx, E-Revo, or the BL E-Revo. If you want to crawl over stuff in a non-technical kind of way, get the Summit.
Thinking about it, Traxxas could have just called this guy the "S-Revo"...

JMHO...

[The Oracle]

Amen.

People are indeed looking at htis thing all wrong- its not a racer, it wont handle worth a cack at any kind of speed. BL is pointless unless you put a crawler system into it, like a fat little 1000kv outrunner and MM esc on 3-4s lipo (sensored would be better, so maybe a novak goat thing or whatever).

You could use a pair of motors, but unless they are 700 cans or larger, its pointless as the single motor is equal to a pair of titans pretty much.

Its a trail truck basically, an MT based non-scale realistic trail truck- treat it as such.

[schofield]

titans are a closed can motor and can not be rebuilt

[HobbyLover]

Duel Kershaw 700-HO would be fun!!

[noll1]

ok maybe Im not understanding something. Someone help me out here. My understanding is that brushed motors burn through their brushes very quickly, I assume this is a brushed motor and I also assume that after 10 or 15 runs the brushes would need to be replaced, just like the titans, is that a correct statement or will the entire motor need to be replaced? I cant see spending 500 -600 bucks on a truck that needs the entire motor replaced withing the first month. Anyone

[noll1]

i called and asked and was told that if broken in correctly the motor and last anywhere from 6 months to a year or more,. if the truck is driven in water they said no motor can take running under water for long periods of time so it will fail quicker. So basically your looking at a truck that will need the motor replaced withing 18 months, and being a sealed can there is no way to replace the brushes. The 18 months is a guesstimate and how you run your truck is the BIG factor. I think Ill pass if thats the case unless the new motor is 20 bucks or something.

[FireWire79]

http://banebots.com/pc/MOTOR-BRUSH/M2-RS775-144

Just an option for a descent replacement for really cheap. Even if you burn out a motor every two or three months, for 10 bucks, menh, no biggie. Its about the same size as the stock motor and should be OK with the voltages that will be getting put through it. Even better, it can be run up to 20v so you know it can handle what we need it for. The only issue that I can see is that it only has two mounting holes on the motor, so it maybe a little awkward to get it lined up on the motor plate, which may need to be "adjusted".

Oh, btw, it is a 5mm pinion, I don't know what the stock one is, but you may have to pick up some new pinions from your favorite brushless supplier.

One more thing. The Titan motors were really good to me. And I was really bad to them. I don't know what people are doing to theirs, but I was running my 3905 E-Maxx totally submerged in muddy trail water all the time, going from reverse to forward to do wheelies on my little 6 cell NiMh, and just generally terrorizing them, and they lasted me over 6 months. So that should give you an idea of how tough they are.

[noll1]

cool and thanks for the input

[HobbyGuy321]

The dewalt motors are by far the best motors out there. http://www.robotcombat.com/products/BP396505-20.html Mine has lasted 53 runs in my e-revo and 2 years of use in a drill, and it is still going strong. Best of all, when the brushes do finally go bad they can be replaced for $3.00 a set. It has never broke 105 degrees. I have not run it in extreme heat yet, but it stayed nice and cool in 70 degree weather so it should be fine.

To mount it all you need to do is drill out the stock mounting plate slightly. Here is my review on the motor. http://monster.traxxas.com/showthrea...ghlight=dewalt

and here is a video
http://www.youtube.com/watch?v=8f7-xGArS7s

I have tested many brushed motors including the kershaw designs 700HO, and the dewalt motor is by far the best brushed motor available.

[aramid]

I think Ill pass if thats the case unless the new motor is 20 bucks or something.

$25-30 is probably about right. The 550 Titans in current Traxxas vehicles are $20, although people generally replace them with a rebuildable modified motor instead of another sealed-can. I suspect the larger 775 motor will cost a bit more, but it's still cheaper than the dual-550 setup in the current 4WD vehicles. And no doubt the market will show up with a few higher-powered replacement motors, if you'd rather not use another Titan.

[FireWire79]

Hey HobbyGuy321, do you think it would be a better idea to use the 14.4v version of the motor?

Just a little more capable of handling the voltages delivered by us. Also do you know if there is a way to get the motor without the pinion on it?

As your the original poster of the E-Revo with that, do you have any issues with it yet? Looks like it will be a great drop in for the Summit when it arrives and I may just go ahead and order one now so that when my Summit gets here I can drop it in.

Oh, one more thing. Never mind, you got the old style one, I am looking to get the new style one that is flush and may have holes for mounting.

[boomerrw]

And I still don't know why you would want to put a brushless system in this truck. It is designed to get wet and dirty. Brushless motors don't like the mud and crud, it is bad for them. I plan on getting the Summit so muddy and nasty every time I take it out that it out

A brushless motor doesnt mind water, mud, and crud.

It doesnt sound like there would be a problem running a mamba monster in water besides the fact that the fan is definately not water proof. The castle esc electronics are supposed to have a protective coating
