Joining the Summit crew.

[Cameron]

Planning on picking up a new TQi equipped Summit tomorrow.
What do i need to know?
Is there anything that needs to be done out of the box as a much do upgrade?

I have heard some mixed reviews on the TQi radio for this guy. Whats that all about?

Blue, or Red, or Green, or Black... that's my first decision. Hopefully not a decision limited by available stock at the LHS. They have 4 on the shelf.

Im kinda Partial to the Black, hoping they have one available.



But the Blue is pretty darn sharp as well.

Lipo batteries. 5000mAh at least.

[MITCH316]

Summits look awesome and fun...have a blast.

[traxstar]

welcome to the summit nation enjoy your many journey's to come..

[Cameron]

Lipo batteries. 5000mAh at least.

I have a stack of assorted SPC lipos. like 5 matched pairs. too bad nothing over 6000mah.

[jamann]

Well all that's left to do is have some fun
Check out the FAQ at the top of the page well worth the read. Gives you a good overview of the truck.
Find some tough terrain and let it eat

I dont know if you have ever dealt with dual servos but I assume you will have to make an adjustment to they dont fight right out off the box. Only been a part of three unboxings but they all needed it.

[SwatKat]

@ stickychinsac: Is this issue that you have mentioned above a common one for Summits? And what are the symptoms I sould observe.. how do I notice that they are fighting each other? Thanks

[jamann]

When the truck is on.lift the front off the ground.If it is buzzing that is a sign the servos are fighting each other trying to center.it is pretty common,minor adjustment but important for the life of one or both servos

[SwatKat]

OK. Got it. Thanks a lot.

[Cameron]

Red it is, im a sucker for what they actually have in stock. I had a choice of Red, Red, and Red... lol



Tempted to maybe buy a new Black shell off Ebay. Or just get my guy to paint a clear one for me

Picked up the Roof light bar as well.

[revomaxx2223]

Red looks nice too.

[stickychinsac]

a lot of people easy off the chrome rims. imo it really sharpens up the look of the stock truck. cheap and easy

[pavmentsurfer]

Gotta do the light bar... its practically a must have. Hehe. Other than that, going lipo is the only other thing i feel is really "needed". The summit is one of the few traxxas vehicles thats pretty much perfect right out of the box. Make sure you break the motor in correctly, take your time and it will last years. Then, go dewalt.

I also much prefer a single high torque servo to the dual setup. So much simpler.

If you really have an itch to upgrade SOMETHING... take a look at the Tbone skid plate and A-arm guards. They really help the truck slide over obstacles and not get hung up on stuff... I love mine.

[jamann]

I second the tbone skids I just have the center skid and it makes a difference

[Cameron]

Those are nice! might have to look into those.

Man I haven't had a brushed anything in so long, there's still break in on them lol. Figured that tech would have caught up to itself by now and figured out how to eliminate that. How are the brushes on these? Problematic? 775 motor cheap enough to just replace if they go bad, or is it truly a case of run it till it's broke then go Dewalt, no questions ask.

** T-bone skids are on the way
Great now I'm modding my 6 hour old summit haha

[Mayberry Kid]

The 775 is a great motor. There are folks on this forum who have run it a long time with basic care. It suits the Summit fine for it's intended role. My son on the other hand wanted a little more speed, so I went with a 14.4 Dewalt. It's a simple and relatively cheap upgrade. You can run more pinion and definately be able to outrun the stock suspension setup(and still stay waterproof).

I can't leave anything alone anyway.

The Kid

[pavmentsurfer]

The 775 is really not deserving of the titan name. Its a WAY better motor than the 12t 550 motor. You DO need to break it in and keep it clean and lubed though, but if you take care of it, it will last a LONG time and give you outstanding power. Most people wear out the bushings on the pinion end before the brushes give up.

KSB ran his right into the ground before going dewalt and I know jakey is still running his original 775... these guys run ALOT... I only went with the dewalt because I'm a compulsive upgrader. Not because i needed to, but I DONT regret it.

Yes, I did though it was only 11 months that mine lasted. In it's defense, I had forgotten I had winter gearing in it (14/58!!!) This motor is definitely happier or stock gearing or one tooth less so I was waaay over-geared for ambient temperatures in the 80 and 90 degree Fahrenheit range. I won't even post what happened to the internals when the motor temps went upward of 220°F. It's embarrassing. Mea culpa.

To me the Dewalt is a very nice alternative, but you wouldn't have to but a gun to my head to make me install another Titan 775. It fits better in the mount, it already has motor wires soldered on, and capacitors to reduce radio interference are installed. Also, you don't have to cut off a funky-pitch pinion or cut/grind a flat spot in the shaft. If you are okay with doing all of that yourself or want to pay a total of $52 to have someone provide you with a motor already prepped (you still have to mod the motor mount) then go with the Dewalt. If you want to take an easier route, replace a worn-out Titan 775 with a properly broken-in Titan 775.

One thing I would also suggest - and pav has done this as well: replace the two male motor and two female ESC power connectors with 4mm bullets (I did this) or with one 5.5mm or larger bullets (pav did it this way, soldering two wires together into one bullet.) I believe some, like Jakey, have gone a step further and directly soldered the motor wires to the ESC or vice versa. Any of these will improve efficiency.

[Cameron]

Roof lights are installed, spending the night with the manual. Make sure i don't miss something glaringly obvious and break it first time out.
Would assume w/o reading the manual being at a stop is preferred for locking and unlocking the diffs and changing gears?

[ksb51rl]

Yes, but 5 mph or less is okay.

[Cameron]

are the interlocking crowns on the diff lock metal?

[jamann]

the locking part is, the reciever(diff cup) is not

[Cameron]

well at least there's metal in there lol.

I do have a question about running parallel batteries. so even though the EVX2 is wired in parallel (visually anyways) it isn't is it? 1 battery powers motor 1 powers everything else? Or how does that work. What jumper is needed to run parallel for redonkulous run times?

[ksb51rl]

The EVX-2 is wired in series internally. To run parallel you need to put a jumper on the non-BEC side and use a parallel adapter on the BEC side.

[Cameron]

got a link for the jumper? or are the a DIY deal?

[ksb51rl]

I've never seen a pre-fab jumper but all you need is a Traxxas female connector and a short length of 12 gauge or larger wire to go from one terminal to the other.

[Cameron]

Gotcha, that's kinda of what i was thinking after asking the question.

I have 2 tires that are VERY out of round/balance. Like A LOT. Assuming the bead is glued evenly (looks as so), this is a foam issue i would think? Chances of giving it a bomb out on the street and they work themselves even?

quick vid.


If im looking at the rim alone, they dont wobble.

[ksb51rl]

The old-timers will tell you that a good hot hairdryer will bring foams back into round, but I don't know if that would work inside the tire.

[Cameron]

Hmmm well new shoes were in the works eventually i suppose. Wasn't planning on them this soon.
I don't see the foam rebounding while inside the rubber as you mention either.

[ksb51rl]

Have you tried the run down the street idea?

[Cameron]

not yet no, i will definitely try that first. i only saw this tonight when i was just seeing how all the linkage is working etc.. drove it a bit and the left front is all over the place but the rim doesn't have any wobble to it at all. Its all in the tire.

_______________________

New question, what voltage is the EVX2's LVD set to and can it be changed?
Didnt see that on the add on to the manual that talks about the LVD version.

[ksb51rl]

Traxxas has never (AFAIK) disclosed the cutoff voltage for either stage of its LVD protection. No it cannot be changed on the EVX-2 or any other Traxxas-manufactured LVD-equipped ESC.

[Cameron]

Seems kinda shifty. I only run mine down to 3.4v as a habit. Well with all the MMM powered rigs at least.

Got some good running in at work today, finally found a truck that can go over the dreaded nemesis of a speed bump at work that has kicked every one of my vehicles over. Summit just absorbs it lol

A handful of passes up and down the parking lot didn't do anything to straighten out the foam on the front tire.

[ksb51rl]

@ tire: sorry.

@ LVD: my testing suggests that the Traxxas LVD is in the 3.4 to 3.5 volts per cell range.

[Cameron]

That's good, i was afraid of them setting it to 3.0 or 3.1 something really low.

I don't notice the wobble while crawling along anywhere, doesn't seem to effect it any different.
Ordered a set of 3.8 Trencher X on Desperados last night anyways. I have never been a guy to not have a few sets of tires for everything lol

[Cameron]

Ohh ahhh, found a set of LT rockers i dyed a while back because they were there. Installed them tonight.
Don't know if i will go ahead with a chassis dye or not.

[Cameron]

Still debating doing the chassis. i'll probably leave it as is. Lots of extra stuff going on with this chassis vs the ERBE-GT i did the chassis on.

[stickychinsac]

love the look of the black rockers

[Cameron]

Thanks

What is the go-to servo for the single upgrade? 7955tg?
