I am willing to bet you right here and now that as soon as it sees a real MT sized brushless system the truck will fail imdiately. The drive angles are too steep, the gears are too low meaning too much torque to the gimmicky lockers and the ride height is too tall paired with the soft suspension meaning it will roll at any speeds above 15 or so MPH. So your telling me the E-Maxx has no steering servo problems? Your telling me it isn't a pain in the ass having to set them every time you take a big jump? And then adjusting the shifting and locker servos is gonna be great fun. So I'm foolishly asking you to answer questions you foolishly think you know. I'm stating facts about the machine, your saying that it looks cool on the video. On papaer this truck is terrible. Kids who like the looks and want lights will enjoy it.

Tempted- I was once young and headstrong myself. I would argue a point till no end. The fault with that logic is that you close your mind to the facts, and the argument becomes about winning, rather than coming to an amicable conclusion about the original question. If 20mph is too slow for you, I suggest not buying a traxxas summit. And, you got me, a highly trained racing greyhound can acheive 45mph, I too can google. I don't recall the exact numbers of the 775 motor, but traxxas states that the 775 has more torque than the two 550's, and they aren't in to false advertising, and you can see the same statement at kershaw designs about the very similar 820 sized motor conversion. There is a lot more to crawling than just torque. I explained in my earlier post that articulation plays a huge part in crawling, making the summit, with the phenomenal revo suspension, a much more capable crawler than any maxx truck. Apparently your reading comprehension leaves a little to be desired. About your bet: the gears have been proven. The shafts are even stronger than the well proven 3.3 shafts. Although race trucks don't sit at the same stance as a summit, that is simply ride height. While racing a truck will see full compression and full droop, going through the complete articulation of the suspension, so the steep angles you keep referring to have already been experienced and handled by traxxas slider shafts. And, back to the gearing, it's been proven. Of course a monster truck setup for crawling will roll if you try to carve a turn at 15-20 mph. No surprise there. Any experienced r/c'er knows to back off before turning to keep her on all fours. Stick around, I could teach you alot. I don't have any servo problems with my e-maxxes. If I did I would upgrade the part that is repeatedly failing, as simply repairing it and hoping for a different outcome is, by definition, insanity. Adjusting shifting servos is actually quite easy, not for you it seems, but it is a very simple procedure. Furthermore, the servos come preset, so why are you so worried about adjusting them? In fact, shifting servos are the easiest of servos to set as they only have two positions and don't need to be centered. You are not saying facts about the machine. You assume the drive line angle is too steep and will fail. You assume the gears will strip. All assumption and no fact. I don't say it looked cool on the video, I say that on the video it actually crawled over rocks that I don't think any of my maxxes could have. Thats fact. You say on paper the truck looks terrible. Maybe you should ask your mom for the big box of crayons with the sharpener on the back, so when you draw trucks on paper they won't look so terrible. If you want to talk crap about anything, upcoming or present, take it elsewhere. Nobody here likes negativity,and bashing on something just because you don't like it isn't tolerated, which is the real reason I wasted the time it took to write this response. If you have constructive criticism about something that may be sub-par, then by all means, share, but if all you want to do is say that sux, tell your mom as she tucks you in. If you don't have anything nice to say, don't say anything at all.

Sounds to me like your getting quite defensive. I'm thinking you need to spend a little less time trying to come up with big words and quizitive remarks and look at the truck as a whole, rather than just arguing to be argumentative which you are so clearly doing. Your wasting your time and mine by trying to negate my logic and insert your own. Revo suspension is great in a RACE TRUCK. Maybe you should ask your mommy to read you a copy of RC Action to explain why independant suspension sucks when you try to crawl with it while she is tucking you in. Oh and those gears you talk about, explain how you know they are strong? Because I know that large tires, low gearing and plastic parts equal breakage. If you are scared that I might hurt someones feelings about a truck then maybe its you who shouldn't be posting on a forum; what do you think a forum is all about? I, too, took english class and can phrase anything into a much more complicated argument than it should be. Tell ya what, get you a Summit, throw a brushless system of your choice on it and video the first run. If I'm wrong, I admit my mistake. My bet is that you won't post the video of your driveline exploding once those tires bind and the brushless motor puts the torque to ALL THE PLASTIC DRIVELINE COMPONENTS. You seem to be hell bent on a sub-par truck when you admit it does nothing well. I've shreaded more Maxx diffs than you can count with a "weak" dual VXL truck. The torque kills the soft plastic cups. If you think these cups are going to hold up to even more torque, larger tires and more weight maybe you should spend some time online. Oh and by the way, I didn't have to google dog speeds. I seem to be able to remember things without having to do a search every time a question may arise. I won't argue with you since it is so apparent you only intend to argue. You don't seem to be going anywhere other than trying to prove me wrong. Chill out, sit in your rocking chair and watch the sunset. I don't argue for arguments sake. I try to prove my point and get out, but it seems others like to try and disprove my comments. Lets not let this get out of hand.
The answer is no. And yes, mine is faster.
