4Syma X1 Quad Bind Process / Radio not working
By Amazon Customer
Hey fellow owners and potential owners!

Noticed others are having the same problem my buddies and I had when I first received the Syma X1 Quad, they should UPDATE THE INSTRUCTIONS ASAP

I had an issue with the radio transmitter not binding with the Syma X1 quad and there IS A EASY SOLUTION.
The instructions are lacking in this area and are responsible I'm sure with a lot of frustration and probably returns.
In between my friends and I we have over 6 of these to date, they all work with this procedure that I quickly wrote for another amazon user.

SYMA X1 QUAD - RADIO TRANSMITTER BIND PROCESS

IMPORTANT SOLUTION TO ALL OWNERS - RADIO NOT WORKING WITH THE SYMA X1 QUAD

1. CONNECT BATTERY TO QUAD, THE LED WILL FLASH SLOWLY
2. LED WILL BEGIN TO FLASH RAPIDLY,.... IMMEDIATELY TURN ON RADIO TRANSMITTER
3. LED IS SOLID, BIND PROCESS COMPLETE. READY TO FLY

After connecting the battery to the quad the led will begin to flash slowly. Have the radio ready because the led will soon begin to flash quickly looking for a radio signal. As soon as the led begins to flash quickly immediately turn on radio. The Syma Quad led on the board will then be a SOLID on indicating the bind process is complete. You are now ready to fly or crash your quad. You only have to do this bind process once. From now on you can turn the radio transmitter on first and then connect the battery to the quad.
** It's important to have the quad on a level surface once you connect the battery so the gyros know what is level, do this EVERY TIME **

4how to switch from mode 1 to mode 2
By Custom Communications
Excellent little machine. When I first turned it on and tried to fly, it flew sideways into the wall. Tried several times with the same result.

solution: First, make sure that transmitter is off. Place battery into unit and immediately place it on the floor or other level surface. Wait for unit to stop flashing rapidly and is flashing slow, THEN make sure that throttle is off and turn on the transmitter, unit will pair with a steady light and an audible beep.

Happy flying. Remember it is a 4 channel. I have yet to flip it, just not enough room where I fly indoors and I have yet to determine where the 'A' button is to change it from mode 1 to 2.

FOUND IT!! thankfully!!

Transmitter off
Hold right horizontal trim button to the right
Power on transmitter
release trim button
display now reads Mode 2

Myself... I am so much happier with the unit now that I found mode 2. I am used to flying coaxials in this mode and find it instinctive making the unit that much more fun to fly.

And yes, I have also flipped it without crashing. Make sure that you have plenty of room because after the flip, it will travel 8-10' in the direction of the flip.

After a few days, crashing it numerous times, still intact and would recommend this to flyers with experience flying coaxials first. Throttle is the most important control of all types of crafts.

happy flying!

5Tough and Great flying machine
By furnic
This is an incredible tough little flying machine and a great way to get in to the world of RC flying and quad copters.
I have purchased various indoor and outdoor RC flying toys and this is the first one that has made it intact after the first week.

First the toy, it comes with a decent 2.4ghz transmitter with a short rubber antenna which can't break unlike the old steel ones of years gone by. The flying instructions look quite complicated but who really reads a manual anyhow and the only way to learn is by practice and it does take a while.

The Quad comes fully assembled and once charged it is ready to fly. Charging time is about an hour and flight time is over 10 minutes. I think continuous fly time would be around 6 - 7 minutes but it will be a good few days until you can keep it in the air for over 1 minute.

We have crashed this endless times, landed in the tallest of trees, got tangled in branches, my garden is now littered with long poles made out of bamboo and pool cleaners to knock this out of 12 meter high trees and still it goes on flying.

It will take about 2 - 3 days until you get the hang of the controller (if you new to this) so if you can keep the temptation down, try and fly and hover just over head high to start off with.
Re the flying, it can do amazing things - it will hover in one spot, turn 360 degrees and circle, go forward and backwards (this takes a bit of time to master) it has a button to do front and side flips, everyone goes ahhhhhhhh when you do them.

The highest I have taken this up is around 33 meters (about a 100 feet), I don't think it will go much higher and the wind at that height gets a bit strong and I'm scared in may just fly away so I haven't ventured that high for too long.
My longest continuous flight so far, after a week, is about 4 minutes long.

after a week, there are still one or two buttons that I'm not sure exactly what they do, I think they may be to assist with the stabilizing - it is quite important when starting up to start it on a very level surface, if not, it just won't fly nicely.
I have also managed to fly it with a keychain spy camera, so it can do some basic FPV photography and its quite fun getting a birds eye view of your property.
If it survives another week of trees and crashing (though crashing a lot less now)then I will buy more batteries as once you get the hang of flying then waiting an hour to recharge can get a bit frustrating.

4Sound specifics
By Andrew Ackerman
I am a musician.

These speakers look great; that is the main reason I bought them. I do wish the sound quality was better. The sound quality is above average, but not great. However, I was able to use software graphic equilizer to adjust the sound to a better balance.

The frequency response is uneven. The tweeters are all very small speakers, 1.25 inch wide, with one woofer unit. Since there are no mid-range speakers, the mid range is compromised. It is not all bad though.

The best feature is great top end response from these little tweeters. Above 8K hz and 16K hz, the sound is very crisp and clear. As I generally like good meaty bass, with high crispness, this is not bad.

The clear plastic bass unit is great to look at, but cannot match the sound of a square wooden box - as is true for concert halls. Unfortunately the bass has an unatural high spike about 120 hz. Also the output below 60 hz is virtually non-existant. Putting the woofer on the floor under a desk might magnify the 30- hz but again it is great to look at, so I keep it on top of the desk. I find the woofer volume best around 60 to 70%.

Here is how I have adjusted iTunes graphic equalizer to over come the speakers' native tendancies (1 = a line):

32 hz +2
64 hz 0
125 hz -0.9
250 hz +0.9
500 hz +0.9
1K hz -0.9
2K hz 0
4K hz -0.3
8K hz -0.6
16K hz -1.2

You will want to increase the mid 250 and 500 hz range to increase warmness. There is another unnatural spike at 1 K hz, where the wavelength matches the dimensions of the stick tubes. It sounds like talking thru one of those gift wrapping paper tubes. Reduce 1K Hz to avoid that. The top can be tempered down to taste; the top is the best frequency range these speakers produce.

The left and right need to be placed far apart. I am not sure if the speakers are doing this on purpose, but I get an uneasy mono feeling if they are too close. Too much focus. I also turned on my computer hardware virtual surround sound which seemed to round out and increase the stereo spread. If you have it, try a computer setting bass boost on as that will increase warmth.

The left and right should be pointed directly at you, not angled away, to get the benefits of those high frequencies.

I got these new for $140, and I think they are worth it. As always, it is best to try before you buy in a store front, if you are that picky. Hope this helps!

5space-age-jelly-fish speakers!
By L. Hartwell
My husband just gave me a pair of these for an early xmas present. I love the way they look, but was a little freaked out when they came out of the box due to the size of the subwoofer...these are for my desk. But we hooked them up and within minutes I was a super happy camper. The sound is clear and crisp and the bass is adjustable. For the person who said that you can't turn these off, you can if you press down the bass control knob. The sticks are attached to a heavy black donut shaped base and you can adjust how they sit on the base so you can point them at your head rather than your chest. One of the sticks has touch volume controls and if you touch both at the same time the sound is muted.

So far I love them. Going to really enjoy listening to music again. I would totally recommend them to a friend.

5Subtle improvements over the previous version
By J. Welch
I've owned the Soundsticks III for close to a month now and have been thoroughly impressed. Harman claims the new model provides the same audio quality as the previous edition. The new version III audio cables are silver braided and clear. Other changes include black bases on the satellites, the black sub volume dial is also the power on/off switch, and there is a white led light in the sub. Input voltage on the power transformer is 100v-240v, so it will work outside the US without the use of a converter. One thing worth noting, since it is not in the manual, is that the satellite with the volume controls is the right speaker.

I find the sound stage to be vivid and non-fatiguing. The instruments and voices are crisp and detailed. I mainly listen to 80's, classic rock, and metal, and all appear to be clear and balanced. I can easily listen for extended periods without being fatigued. IMO this is one of the best 2.1 computer speaker systems available. You will not be disappointed.
