Soma X8W Take off

I have a thread on the forum - which originated due to a a defective Syma X8W from EverBuying in China. Apart from its other problems - the radio was showing Mode 2 and was in Mode 1 and seemingly not 100% functional in that mode! As you have seen in the replies above - flipping is usually due to a motor problem. If when driving your car it veered to the right - it would indicate a problem with the right front wheel. A flat tyre...so the left wheel is still pushing - the flat tyre is adding drag and and affects steering. Same with the Syma motors - they are not all working equally according to the throttle.
IF you have checked and found no problems with the location of the A and B marked props and the motors seem to be working OK..... then none of us can work out what is wrong.
Quads are basically very simple technology - the motors spin in different directions to counter torque in the opposite. In these days of computer controlled aircraft and jet engines - its not the problem it was years ago.
From the video yours acted by moving forward - its held by the landing gear and starts to tilt. You could ease back the right stick to counter the forward push - which is allows you to - hopefully - stop the flip starting and then use the forward direction trim tab to hold it back.
I take it you are not pushing the right stick forward at the same time as pushing the left stick -- throttle forward. The right stick should be in "neutral" position till you get some height.

Did you buy from a store China - or a local store such as JayCar? If it is a defective quad and / or radio - then return it to the store.
If you bought from a store online and in China, welcome to the club- who's members all paid good money for bad products.
Check my first thread for the saga that is still ongoing today!

Q 102, I had read your thread re your continuing saga earlier, but as always you never think it'll happen to you. I did buy from China, a Company called Banggood and having communication problems with them at the moment. Ring any bells?
I have attempted to adjust right-hand stick on takeoff to allow for movement. As I mentioned, the drift can be in any direction and any movement of the right stick fails to correct the drift in time. I've also tried to adjust the trim buttons, but seems to be too much adjustment even with slight tap.
I understand and appreciate your advice, really.....but to be honest, I don't see why I should have to perform these fairly fiddly tasks just to get the thing into the air. I'm familiar with helicopters, and even the most basic one manages to lift straight off planet earth!
My personal saga continues!

I have used - and will likely use again - BangGood. Despite all the rubbish from EverBuying... all my orders from BG have arrived on time.
I cancelled an order because I realised I had opted for teh wrong option - No problems with BG - refund to PayPal automatically. They cancelled an order for some ESCs - because they had no stock... and again Refund to PayPal. So at this time - I give credit where its dues... and grieve in huge amount to those who rob me!
Most of the older hands on this forum have and still are I suppose - been involved in either or - or both - fixed wing and Heli's so there is a wealth of knowledge. I am a newbie really.
But I currently have a Degree in YouTube watching and a Certificate in Forum crawling to glean information! That and have owned a defective Syma.
Driving down to Sydney today a thought struct me... as far as I can see, you have not mentioned which mode you are using. if you read my troubles.. part of teh cause was a faulty TX which was not in Mode 2 as it displayed.. Now my thought was...have you tried changing to mode one - read the manual for how.... and if you don't know Mode 1 check the stick moves in the manual.
Correct you should not need to mess about - and had you bought it from Hardly Normal et al - you could have taken it back. As it is - you joined the merry band who have come unstuck dealing with cheapo Chinese "toy" quad sellers.
If you have not ( even if you have..) sent a video - to be honest if you sent the one I saw - my reaction was what you read - and I bet their's would be too.
So my suggestion is to reply to the open support ticket - or start a new one and write that - It will be a risk to the quadcopter if I send it high to demonstrate how defective it is, so if I need to send a video to prove this item is not fit for use and could be dangerous to people I need BG to approve and accept that any damage which may happen is NOT MY FAULT.
Of make a video - get the camera well back to take in the full scene and send it high with the stick going from Zero to max in one move.
Maybe it will convince them. If it incurrs damage - they see how it occured and why... defective item!

If the quad is acting as you say - using just throttle - with no forward pitch applied - its a motor or prop or motor and prop issue one or both are not functioning as they should.
My props supplied needed balancing - if you know heli's maybe you know a fixed wing guy or other quad user who has a prop balance and eliminate that from the list.
I suggest you visit youTube and search for Syma X8 and there are plenty of vids.. a few show all manner of flyaways and malfunctions.
If you know fixed wing / heli's with their own TX.. most can bind with Syma - from DeviationTX.com devoted to Walkera Devo 7,8, 10, 12 versions This shows - it will bind Syma X8C Quad NRF24L01 SymaX.
IF you could get help with this and try a reliable TX, it may help - or at least just prove your TX - is OK.
Other than all this....and the fact that nobody can add any other suggestions - it looks like motors and or props being a problem - or a faulty fight control circuit board.....

Last Word on dealing with China - expect delay after delay - can you try.... send photo send video, repeated at least twice... to get anywhere you need to be pro-active - being Mr Nice Guy just does not work when your money is their bank 5000-6000 miles away. To me that means threatening to - and using PayPal or your CC company to get involved.
 
OK... news of sorts.... I had tried switching between Modes 1 & 2 before and nothing changed.
I just started it up and it was showing "Mode 1".... switched to 2 and no real improvement.
Switched back to "1" and I managed about 30cm off the ground (inside) Best ever result !
Would love to try outside, but, wouldn't you know it, first rain for about 2 weeks has set in!
Have to wait for further trialling but looking promising. Do you know the tech details of difference between 1 & 2 modes?
Anyway, thanks for your persistence with my problem.... much more than BG has done!
Further updates as they happen folks.

Basically the sticks swap position Left throttle become Right Stick throttle - and back wards - forwards is on your LEFT stick - this was part of my problem!!
I think the manual explains the different modes- also my mode 2 was corrupt and did not even act as Mode 1..
When the TX indicated my mode... I was in Mode 1 but the sticks acted for mode 2.. so the display was wrong. Now some things show not what you have - but what is available - if you follow that!
Indoors with a bit of throttee - move the " direction" ( mode 1 = is now left stick) stick up - down - left - right and you should see the quad tip slightly in the chosen direction.
Try on both modes and check the results.
 
Thanks, that's interesting... When I switched between 1 & 2 modes... the left remained the throttle in each mode. (I don't know about right stick, basically haven't been able to sue it yet!) Just checked that again, and no matter which mode I select, left stick is throttle. Could they have changed the procedure? this is a brand new bird (I hope) and in Orange although the TX is red/white.

Sound just like mine! Practice a bit and you may find a "true" mode. You will know the stick moves or better still find out which mode setting give you one stick with throttle - and left and right "yaw" one stick should have forward - backward - Left and Right with a quad this means - assume your quad is in fron of you pointing away from you. Now if its hovering 3 feet up and stays still - if you move the stick left... the quad will move left - still facing the front- same with right. Move the stick up and it goes forward in teh direct facing - reverse this for... backwards - towards you.

Now while it still imaginary in hover - if you move the throttle stick to the left - while NOT reducing power power and slapping it in the grass... the quad will spin on its access to anti clockwise... push the stick right... clockwise spin. Those are you basic stick functions and results. You need to find what your TX is doing with each of the stick moves.
OR find an X5 TX whcih will work with the X8 and better still if you cab get an orange and white version. Advertise on Gumtree to see if anybody has a wrecked quad and will sell the TX .

Ask BG to replace the Tx... its a cheap solution for them.
 
Mode 1 on Syma transmitters is what we call Mode 2 in the USA. Most U S flyers use Mode 2. Switching moddes on my Syma transmitters swaps the yaw and left/right, out of the box yaw should be on the left stick.
 
Despite BINDING, this is NOT the same as a CALIBRATION with a quad or any other rc vehicle...To me personally it sounds as if the gyros are out of sync..creating more power to the front motors allowing it to pitch forward.

Look on youtube for the "CALIBRATION" procedure and, make sure it is on a flat surface when doing so...If that doesnt work you have a faulty gyro.

No matter what mode you are in it should have no effect on rather or not it takes off correctly..All will have "some" drift on take off.
 
Thanks Mike H, Yes.... I've calibrated the Quad... and realise the binding is not the same thanks. I've been looking at getting one of these for about 6 months and have a "Degree" in YouTube, Blog posts and other advice rooms concerning the opening, checking content, charging batteries, safety procedures, avoiding the trees. etc etc. The problem is it flips in different directions as well.. not just one direction all the time. It does behave a little better in mode 1 for some reason. but the strange thing is, the sticks stay the same (left lift and right steer) no matter what mode I'm in and I'm guessing it's not the craft at fault as much as the TX
 
Read up on how it performs its flip modes...im not thinking it has an auto flip function with the throttle but maybe a button stuck on the transmitter or something.

If fully calibrated and in the proper mode im not sure of anything else that it could be but a bad gyro on the board...And i suppose youre positive the props are correct also, so thats eliminated as well.

Option one is a return or replacement which might take a while.

Option 2 is just buying a new Flight board for it and replacing it..i think they are less than $10.00 and youll need to do some soldering unless the board uses plugs.
 
I've waited 6 months to buy the thing... a little while longer waiting for a replacement should be bearable. I'm certainly not fixing their error!
Cheers my friend!
 
I've just heard from Banggood that they are sending out a replacement Syma X8W.
Fingers crossed that this one is going to be OK!
Many thanks for all the people that offered assistance and advice in the last week or so.
It was just a "dud" I think.
Cheers everyone, will advise when new one arrives and is checked out.
