Thanks Gyrobob for posting your mod.I like the idea of the Husban HIO7d battery and just bought a few from Amazon and will give you update when they arrive.Keep those mods coming.
"Fly like a butterfly sting like a Syma" http://syma107.com
I replaced the latest failed motor with a used one.
I removed the landing gear, the camera, the camera door, and used only about 8 of the screws to reassemble it.
I used a smaller battery,.. the battery that fits the smaller Hubsan H107d.
What a difference!!
-- You can tell the motors are just idling along with much less noise.
-- Even with the smaller battery the thing stays airborne for about 8 minutes.
-- It seems more stable too, but that is a somewhat subjective assessment.
Now, we'll see if the motors stop failing so often since they seem to be under less strain. They are not even warm at the end of a flight,.. they seem to be around room temperature.
I might try removing the prop guards to get rid of even more weight, but I worry about crunching a prop now and again.

Reason asked if using stock battery is I tried a few crazy things this week. First I flew the X5C and crashed it into the ground and left motors running for awhile one prop buried into the ground not spinning, motor was ok. Next I tried with bigger battery 700mah still ok.However I then started to add grams of weight still using the bigger battery, what I noticed was the motors were getting much hotter after 5 mins of flying, so then took it to the bones no camera or prop guards still with bigger battery, longer fly time motors a lot cooler..
So the idea came to me there must be a way of testing a brushed motor to the amount of weight and energy it gets to burn out..now do not ask me how to test that, no bloody idea, but the morale of the story is, I presume more weight is the problem not the amount of times one flies the basic X5.. does that make any sense or am I kidding myself?
I agree with your weight vs longevity concept. I think I'll try what you suggested,... taking off the camera, the battery door, the prop guards, and landing gear. I think I'll drill a lot of holes in the housings around the motors as well, increasing the amount of cooling air.
I think a larger battery would be counterproductive for two reasons:
-- more weight
-- no increase in performance because motor power depends on voltage, not battery amp-hours (wattage). This is true assuming the stock battery is strong enough to maintain rated voltage. If the stock battery is simply too small because of poor initial electrical design, then a larger battery of the same voltage would help,... but if the stock battery is adequate, a larger battery of the same voltage won't add more power. In fact, the overall drone performance might even be worse because of the additional weight.
Since I have two other drones now with better FPV performance than the x5c (with the syma FPV kit), I can use those drones for FPV and video work, and use this lightened x5c for just flying around, practicing my non-headless-mode chops.

Hi Gyrobob,
Think Redfive is trying to give his best ideas to the forum and is trying to help all.
I agree Syma needs to upgrade motors and keep the price low..if you look at video below you can see the competition in the market place, even tho the USA is bringing out laws, this hobby is not going away.
Also thank you for info "I have improved the situation somewhat, though. I don't have to split the body anymore to replace the motors. I leave the solder joints in the middle of the wires sticking outside the body, so to replace the motors, all I have to do is unsolder the broken motor, slip it out, slip in the new one, and resolder."
Stay cool, I do love my X5C and have done mods on them, however not very successful. Just one thought are you still using the stock battery?

Yes I did mean allowing the machine and batteries to cool. If flying the things to destruction is your thing then fine but if you were to buy 2 or three machines you can still do the amount of flying you have done without regular changing of motors
Cute comment. Silly, but cute nonetheless.
'flying them to destruction' Not quite. Why would I want to fly them to destruction? This thread is about just the opposite, eh?,... not destroying them so they can be enjoyed. I surmise you just jumped into the middle of the conversation without understanding what is going on. Read some of the posts and maybe you can make some meaningful comments.
"Buy 2 (sic) or three machines" Another cute/silly comment. Maybe I should buy 31 of them and just fly a different one every day of the month.

The 15 minute rule applies to letting batteries cool down for 15 minutes before recharging think Redfive is saying if flying so much let motors cool down for awhile, hence have two quads, guess that is what he meansSo what is it, batteries or motors? I never put a warm battery on a charger.
I did mention a few posts ago: "Maybe if I only fly for 3 minutes at a time, and let the thing rest for 3 minutes in between each flight, the cheap little motors might last longer. What a pain that would be!! If so, it is a shame they couldn't have built in a little more quality into the motors."
Is three minutes all the flight your x5 gets? I get five to six minutes and most of the comments I've read by others on flight duration refer to an average five minutes.
I agree the limited flight duration can be annoying but, as someone else has noted, the alternative is a $400 - $500 version.
It gets around 5 minutes before the LEDs start flashing. I was theorizing that if I only flew 3 minutes at a time, with a 3 minute cool down period between each 3 minutes of flight, maybe the fragile little motors might last a bit longer.
Instead of spending $600 to get a drone with adequate motors, it would seem Syma could spend another few bucks on motors and still keep the cost reasonable.
I have improved the situation somewhat, though. I don't have to split the body anymore to replace the motors. I leave the solder joints in the middle of the wires sticking outside the body, so to replace the motors, all I have to do is unsolder the broken motor, slip it out, slip in the new one, and resolder.
Now all I need is a source for a bulk order for motors.
-- Banggood has the motors for $1.89. I could just order eight of each motor,... that ought to last me for a while. $30.24 for 16 motors.
-- Amazon has them for $6.46 in sets of four. $1.62 each. $25.92 for 16. Even cheaper.
-- I wonder how long it would take to burn out 16 of these motors?
-- At these prices, it is obvious how "heavy-duty" they are, eh?

Wow 7 motors, I have two X5C quads and myself and friends fly them for the last 6 months never had to replace a motor yet,but I do not do fpv with them, motors cannot take the extra weight.The FPV system is designed specifically for the x5c. The "extra weight" is less than 1/2 ounce. I doubt that tiny bit makes any difference.
I am beginning to suspect the motors overheat and self-destruct if you don't let them cool down.-- Sometimes I will fly four batteries in a row,... fly for 5 minutes, put in fresh battery, fly for 5 minutes, put in fresh battery, fly for 5 minutes, put in fresh battery, fly for 5 minutes, put in fresh battery.

-- On the other hand, this thing IS just a toy, so maybe I shouldn't expect it to last very long.
They are brushed motors and can overheat, reason not brushless motors is because the weight would be too much and then of course the price goes up then you look at spending $300- $500 for a bigger quad like a dji phantom..just give them a cool off period after 2nd flight

I would suggest obeying the 15 minute rule and if you really need to fly that much buy a spare one and alternate them as you fly.

Is this thing a SYMA x5 with a different label?
http://rover.ebay.com/rover/4/.....Ccrd%3DcrdOr
It certainly looks like an adaptation of the x5. In the comparison photos there's no question that the "VS" transmitter is an x5. The body of the quad looks identical to the x5 so it's unlikely that the motor size is any different. So it's likely that SymaFreak's assessment of your burnout problem, overheating, is right on. I fly my x5's a lot, rarely more than one battery duration, and they just keep on ticking.
I recently had one stuck up in a tree for two weeks during two heavy rainstorms. I had given up on it but a hurricane knocked it down (about 40 feet). I thought for sure it was done for, but to my absolute amazement when I dried it off and changed the battery it took off and flew as good as day one. And I even managed to get the same battery charged up and working again.
Syma's S-107 and x5c are toys -- but amazing toys which to me are worth a lot more than I paid for them.

Ditto.
The only time I've had to replace a motor was a defective one right after the first flight with my first x5. Since then I've flown countless times, only a few times with multiple battery swaps, and I've never had to replace another motor. So I tend to agree with your assessment.

I am getting really fast at replacing x5c motors.
Since I have had mine, I have replaced motors 7 times so far. I can get the thing popped apart, unsolder the bad motor, solder in a new one, and re-assemble it all in 28 minutes.
Not too bad, eh?
I think the next time I have to replace a motor, I am going to leave some of each pair of wires to each motor on the outside of the body. That way I won't have to take out a zillion microscopic screws in order to get to the wires. I'll just leave it assembled, clip the wires to the bad motor, remove the bad motor, slip in the new one, and solder it up.
At this rate, this toy drone will have cost me as much as a real drone pretty soon, not counting the many hours of labor devoted to motor replacement.
