So I got myself a alias. Love it soo fun to fly. So I went out and got another one. Boy its fun flying 2 of them at same time. With 2 people of course. My first alias I'm still waiting on replacement motors from traxxas latrax. So I went out and bought 6634 pack of 4 motors. I have gone threw 3 of them already in last 4 hours. Noticing that when I land alias or if it comes down and hits the bottom on the floor is the weak spot. (Rubber feet hitting concrete or asphalt) I was doing the 5 flip and last one hit the ground right where rubber feet are and bam front left motor went out. Replaced and had a similar incident happen again only bam back left motor hit and instantly stopped spinning. One motor feels like its real tight when spinning. Other mother free spins by hand but nothing when power to it. Hopefully traxxas can fix this because I know have 2 alias down for motors and I gotta order more and not about to go pay another 38$ for motors. Please fix traxxas.

I share your sympathy, love the Alias but it does need motor upgrades fast, after 3 burnt motors I took the time to have a look inside and found that the "brushes" are indeed the weakest link. I haven't hit the concrete while landing hard or crashed into something else but after several flips and 'aggressive' turns and can only assume that whenever auto-leveling from a aerobatics the Alias draws a bit too much current which burns the tiny tiny 'brushes' in the motor..
crappy iPhone pic but clearly visible the left side still intact , the right only has 1 of 3 contacts left..
O yea I can see it real good. well I hope traxxas figure out to strengthen the motor brushes. I should check my old ones and see. Thanks for pic and info

Shhhh you guys better stop talking about this. The mods don't like this topic lol... They will probably lock this thread... But don't worry, I'm sure the guys at Traxxas hq are already on the phone with China telling them to beef up the next batch of motors... And to their credit I think Traxxas has been pretty good with the folks who have had motors go out do far.. Myself included.. although its been 15 days since I spoke with Traxxas and my motor has yet to arrive. I hope it's at least on its way..
I agree it could be hard landings that contribute to motor failure.. My advice is don't land on concrete. Only land on grass. Or even better.. I just fly mine down to just above my height (within arms reach), get it in a stable hover, then just grab it from below with two fingers... Then once I've got it kill the throttle. No shock at all this way..
I agree they definitely have taken care of me in sending out replacements for this slash and qr-1. I have been doing that recently. Flying it back to my hand. I like talks of a return back to transmitter function later on down the road. Mainly a camera would be awesome. But yes much better having it fall in hand. Most of time it happens when I do the 5 flips and last one always pulls it down a bit and tends to just touch n hit ground before the pull goes up. One heck of a quad chopper traxxas. Major props for it and hope they nail the motors getting beefy. Fly on and have fun

this quad is so fantastic i could not imagine traxxas not taking care of the motor issue they did everything else perfect when they drew the little dude up i love it motor trouble or not..................
I have come down hard on the pads many, many times and I seriously doubt that has anything to do with motor failure. A sudden drop may expose a flaw that already exists in your motors, but I've done 30' drops onto solid concrete several times with no adverse effects. I have been through 3 of my original 4 motors, but I also carried around a camera and a DR-1 helicopter for several battery packs each and that definitely does stress the motors.

I'm tending to go along with theory of RobertE. There have been several owners with many flights with no failure. There have been several owners with premature failure, myself included. I only had 12 flights. It "seems" those that max out the abilities of the quad in FAST mode are the one with the short motor life. I fly it in wind, fly it fast, and have it do many flips with every charge. I didn't see any caution against this in the manual. I think it's those that fly it mildly in nearly now wind with the occational flip that are seeing prolonged motor life.
since I'm based in EU I can only rely on the help of the LHS to get the motor replaced, I've sent the first 2 motors for warranty replacement so wasn't able to check those, I can only assume there is a reasonable limit on the number of motors I can sent in for replacement.
Let's hope for a quick resolution from our friends @ Traxxas
I'll do everything in my power to help out anyone and everyone involved in the hobby. After all; none of us would be here if no one helped us.
I concur with your viewpoint on bashing also. It does nothing but hurt and annoy everyone involved.
Could a Traxxas employee confirm the motors are out shipping? I was told on the phone a week and a half ago that they were starting to ship them out? I have yet to receive. I'm really looking forward to using my one Christmas present again LOL! Thanks!

I may have made a mistake joining here I have a hard time with forums that do not allow their members to pass along things that can improve the quality time with the product they purchased and also rule quoting gestapo mods. I have already read the rules I do that before I join any forum but I have also found that good mods have allowed moderate bending of the rules from time to time being a Ex mod from many RC forums. I find that is not the case here, more's the pity.

Speaking of.. I'm about due for another alias flight. Off I go.
About the moderators and forum... Its always been this way when using a forum that is biased or owned by the company whose service or product is the purpose of the forum.. This one is not that bad... Although I don't understand why they object to people posting places to get good deals on TRAXXAS products... I guess they don't want to tick off their dealers who charge higher prices??
Anyway all in all this forum and the mods are pretty ok.... I used to be on a Sea-Doo forum that I later found out was owned by a crooked guy named Glen Perry who also owned a big online Sea-Doo parts store and also was a Sea-Doo dealer. Anytime anybody posted anything even remotely negative about his shop (PPG)-which was a joke btw- he would come on and blast them or delete their post and block their account... I also used to be on a Corvette forum and I once posted on there about a rude and unprofessional cop who pulled me over for passing him... Little did I know the whole forum was run by a bunch of retired cops who don't believe in the 1st amendment lol... They banned me.. I had to make a new account and spoof my IP address lol...
If you have to insert spaces or symbols in a word because the language filter blocks it, you should not be using that word here. Please be careful.

Its no secret that there is a design flaw., whenever it lands .... ever., It touches down onto the rubber plugs that are directly in contact with the motors., In less your into the habit of flying into street signs. So ( I realize this is heresy) I bored the rubber plug hole to Lego size and replaced it. Which, it wasn't far off to begin with. It fits perfect with my kids Lego missile part. They wt the same as the black plugs 0.3g untrimmed now @ 1ich long, the Lego buttons wt less than 0.1gm and fit into the space like they were made for it. This makes the footing flush, and not directly in contact with the wires and motor cap. Its marginal at best, but I hope it disperses the impacts along the arms more and less on those High-output motors. Willing to try anything at this point to disperse that force along the arms & not the motor assemble. Once the new motors are here its, tack them in place and give it a go.
A design flaw should be more apparent than the failures we are seeing. I'm flying the whatsis off mine and not landing all that easily and I have not have a problem.

Does anybody remember the terrible crash of the United Airlines DC-10 in Sioux City, Iowa back in 1989?
A bad motor was the cause of that crash, but it was not a design flaw.. It was a defect in manufacturing.. More specifically there was a defect in the raw material (titanium in this case) that was used to make the fan disc for 1 of the motors:
"National Transportation Safety Board officials were on scene within hours of the accident. The rear section of the aircraft containing the number two engine was intact. Because of this, investigators were easily able to see inside engine number 2. As the investigation unfolded, it became apparent that the entire fan disk and blade assembly from engine number 2, a component approximately 8 feet (2.4 m) in diameter and made of titanium alloy, was missing from the accident scene. Despite an extensive search in the weeks following the crash, the missing disk and blade assembly could not be located. Realizing that that disk potentially held the key to understanding the reasons for the engine failure, the engine's manufacturer, General Electric, offered a $50,000 reward to whoever located the disk, and $1,000 for each fan blade. On October 10, 1989, three months after the crash, Janice Sorenson, a farmer harvesting corn near Alta, Iowa, felt resistance on her combine, and after getting out to investigate, discovered most of the fan disk with a number of blades still attached partially buried in her cornfield. The rest of the fan disk and most of the additional blades were located later in the harvest.
Examination of the fan disk did indeed solve the mystery. Investigators discovered an impurity and fatigue crack in the disk, and traced this defect all the way back to the initial ingot formation in 1971. Titanium when melted reacts with air which creates impurities; to prevent this, the ingot which would become the fan disk was formed using a "double vacuum" process: the raw materials were melted together in a vacuum, allowed to cool and solidify, then melted in a vacuum once more. Interestingly, this disk was from the last batch manufactured from material using the double-melt process. GE had changed to an improved triple-vacuum process in January 1972 because of their investigation into failing rotating titanium engine parts. Afterwards, the ingot was shaped into a billet, a sausage-like form about 16 inches in diameter, and tested using ultrasound to look for defects. Defects were located and the ingot was further processed to remove them. However, some contamination remained.
The contamination caused what is known as a hard alpha inclusion, a brittle part of the metal, which cracked during forging and then fell out during final machining. This formed a cavity with microscopic cracks at the edges. For the next 18 years, the crack grew slightly each time the engine was powered up and brought to operating temperature. Eventually the crack grew large enough to cause structural failure of the disk."
Maybe we can ask the NTSB to investigate the Alias motor failures? Thinking about something like this where lives were lost really helps you put something like motor failure on your quadcopter into perspective. 111 people were killed in this Crash in Iowa, but thankfully, and thanks to the skills, leadership, and training of Captain Al Haynes, the rest of the crew, and prompt response of the first responders, 185 people survived..
i just picked up my second alias. the first one was great but only last about 15 flights before the front right and left rear motors died! i spent 40$ replaced all 4 motors and now after about 5 flights the same two motors died again! so i figured it was a lemon and purchased another one because it is a very fun quad to fly. i have 10 flights on this one and the same two motors are dead!
i was unaware of any warranty on this issue! i had just come to the conclussion that while it was a great idea it needed some work from traxxas! so i opted for another brand quad.
how do i start the warranty process you all talk about?
i am new to the traxxas line of stuff so i am willing to give it one more shot!

I've sent the motors to my LHS but it has been quiet for too long , Alias is too much fun to collect dust, it want's to fly :-) and with the current x-change rates the replacement kits are getting close to USD58 on this side of the ocean :-(
Yes they are an authorised dealer, hopefully they will come through and send the replacements.. , I would however prefer a direct contact with Traxxas support somewhere in EU. Wishfull thinking I know :-)
