||Just an awesome all-around truck. If I could have just one RC, I think this would be it. I don't do rock crawling really, but I love the exo-skeleton, LED light set, sticky tires, and plush, long-travel suspension. The light set actually makes it realistic to be able to run this at night.
The Hi-Lo shift servo stripped when I tried to loosen the allen screw holding the horn on. But Traxxas already has another one on the way to me. If it strips again, I'll bite the bullet and buy a decent servo.
Out of the box, the rear suspension is too soft. Plan on dialing in a lot of preload, or replacing the stock double-yellow-dot shock springs in the back with double-orange instead. Then, not so much preload will be needed to keep it from squatting all the time.
The cantelevers for the suspension run on ball bearings.
The battery trays are a pretty good design. They could make it a BIT easier to get to them, so the truck body wouldn't have to come off to change batts.
The TQi transmitter that comes with this truck is great. I like the ability to adjust the trigger travel to 70/30, so that more precision is gained in the forward direction. I've ALWAYS liked that about Traxxas transmitters. It takes only 4AAs. (finally) It's nice and light, and is shaped well to fit the hand. Too bad the programming is so cumbersome, with only two buttons and one bi-color LED... After trying for an hour, I could NOT set the reverse end point to 50%, when I had the trigger set to 70/30. Very irritating. I wish they'd just raise the price by $10 and include a proper display. If so, I'd get rid of my Futaba radio.
The truck comes with a full set of good quality tools. For example, the aluminum turnbuckle wrench is blue anodized, and well polished. The Summit uses special big lug nuts, and it has a custom T-handle lug wrenc that is included. Two of the three included allen keys are also T-handles, but the one short end can also be used for breaking loose tough screws.
A full instruction manual is not included, and this really sucks. They make us go online and download it. The cheater card no longer is included with the Tx, and it is really needed to program this radio on the fly, unless you have the iPod dock option.
I took this bashing in the snow last week, and it does really well in up to about 3" of loose snow. After that, it's so heavy, it digs itself in. The suspension arms and turnbuckles are big and thick.
The truck is not fast, 21 mph on the stock 7c packs. Bu it doesn't FEEL slow, unless you drive it right after something that is a lot faster. Acclerate too hard, and it squats. Brake hard and it dives forward. Corner hard and it leans way over. With suspension this soft, so it can crawl, it cannot really be run high speed.
There's no need to run out right away and upgrade to 2s LiPos, but they do help acceleration. Top speed is the same as on 7c NiMH. The included brushed motor is pretty nice quality. Take some time to break it in properly by taking it out of the gearbox and running it on low voltage for a while, to form the brushes to the commutator. It is fan cooled, and the truck makes a nice turbine sound as it cruises around. (unless you over-tighten the diff, then it just whines around ) The Titan 775 motor feels perfectly adequate. But when mine burns out, I may try an aftermarket motor; I hear the DeWalt 820 drill motor fits this. I won't go brushless unless I can find a complete waterproof one. (as opposed to the Castle Mamba system that comes with the E-Revo Brushless Edition)
The Summit doesn't jump that well, it seems to want to stay nose-up. I found it odd that no battery chargers were included. I expected at least a couple of the new, automatic 7c wall wart chargers. They're humble and slow, but they work well. Plan on another $50 for a charger on top of the purchase price of the truck.
I'm glad I bought this, despite the cheap gear shift servo. I'd buy it again in a second.
