Walkera Hoten X Review - Devo 10 Transmitter - UP02 Upgrade Tool/UP-02 Adapter
Walkera HM Hoten X Quadcopter - 200 size brushless quad - 4 Channel
WOW! This is huge! I can't wait to fly it.
I charged up the battery and took it outside for my first flight.
I was expecting it to be very loud but it wasn't.
It has a low pitch sound to it.
I lifted off and hovered it around for a bit to see how it handles and how stable it is.
It is very stable! Even more stable than my Ladybird QR.
This is my second quad. I was able to fly it pretty easy the first battery pack. Just need to get use to the big size and power of it.
I have found out that using the telemetry eats up the battery time.
I went from 5 full minutes of flight time on my Master CP with telemetry
inhibited in the TX to 1:25 minutes flight time with the telemetry enabled.
I found the same thing with my Mini CP, 1:25 minutes flight time with the telemetry enabled and
3 minutes flight time with the telemetry inhibited.
My friends Mini CP had the same results as I did with telemetry inhibited and enabled.
I set the Sensor Setting - Voltage - External: V1- Alarm Voltage to 3.5V. This give me 3.72V per cell no load which is pretty good.
The Quad feels like it is built well.
The landing gear is wide and sturdy. It has 4 rubber tips on the ends of the landing gear.
Motor booms feel strong and the motors feel like they are mounted securely.
Canopy feels strong.
Battery tray holds the battery in very well.
It has 4 bright LED lights. Two in the front and two in the back.
The front two are white and the back two are Red in 6 axis mode and Blue in 3 axis mode.
The lights help you see the quad from a distance and help you with the orientation. Also the lights look good at night.
The two orange props are big and bright. You can see them from a good distance away which helps you with orientation.
Battery life is good. About 10 minutes which is very good for something this big using 4 BL motors.
It has a telemetry feature so you can monitor your Quads battery voltage but you must upgrade the firmware to use this feature.
The first thing I was concerned about with a Quad this big was safety. Being cut with such a big prop powered by a BL motor.
I posted a question about this. The answers were good to know.
See post # 419 and below.

Walkera did a good job with this Quad. It looks and feels like it is made well. Flight time is very good.
Power seems good for a Quad of this size and weight.
This will be great with a camera on it. I am looking into getting one for this and will add information and videos to this review.
Hobbyone sent me the Hoten-X, Devo 10 TX, and UP02 + UP02 Adapter Package to review at my request.
Thanks Lena for sending me the samples to review!

Walkera Devo 10 Review
The Devo 10 is really nice. It feels good in my hands and the joysticks feel smooth.
I am using a 3S Lipo in mine so it is lighter which is great as it takes 8 AA batteries which make it heavy.
The LCD screen resolution is high and it contains graphs like the WK2801-PRO. LCD screen can be viewed in daylight.
It has Telemetry features which include voltage, temperature, rpm and GPS.
Firmware can be upgraded with an adapter and firmware on Walker's web site.
You can load model settings for different modles from Walkera. You can also export model settings.
It has a vibration alarm which is a great feature.
The menus are easy to work your way through. I was programming it as fast as my WK2801-PRO.
There are a lot of features in this transmitter and at a great price.
I will add more information and videos soon.

Walkera UP02 Upgrade Tool and the Walkera UP-02 adapter
The UP02 Upgrade Tool/UP-02 adapter worked well for me.
I updated the firmware on the transmitter for my Devo 7 and Devo 10,
Imported/Exported models for each of the transmitters,
and updated the receiver firmware for my Hoten X, Ladybird, and Mini CP.
See my post for How to update firmware on the Devo TX/RX and How to Save/Load Models.

how does the trim system work? I see 4/20 but I don't get it. My LB has left drift and I ended correcting it with subtrim, so got me trying to find explain information about the trim... can you explain me the trim setting? Thank you.
|Sep 14, 2012, 04:36 PM|
For a 3 or 6 axis gyro you are not suppose to use any subtrim or trim from what I have read.
Some people do though and it seems to be OK.
I don't know how the trim system works, good question.
They show it in the PDF owners manual on page 19 but don't explain in detail how it works. See picture in thumbnail.

Isn't it something? I've been researching about the trims. When you set it to 0/20 then the mechanical trim don't work. My theory is that the value given is the number of steps each time you move the trim, so if you move it once to the right, then your trim is 4, twice is 8 while if you set 1/20, then your trim advance one at a time. Like the Tunirgy 9x.
I will research more.
I used the subtrim in my LB and now I get it to hover almost perfect, but if it's not advisable, I will remove it.
I'm new at this and now following all your gides, I have the V911, LB and my challenge is the mini cp which I just finish setting and have to try.
I really appreciate all your post helping people learning like myself.
A big thank you to you!

Tom, can you check one thing on your Devo 10. Set the sensor voltage alarm on the 2nd sensor (main flight battery) and fly the LB and the Hoten with 3 packs back to back (i.e. without turning off the TX). On mine, the alert kicks in very early (at about 3.9, 3.8V even when it's set at 3.5).
If I then turn off the TX and rebind it runs as I would expect.
It looks like there may still be some bugs in the Devo telemetry code - would be great if you could make a second opinion.

It is, I have been searching around also and can't find anything.
If I find something I will let you know.
Your theory sounds like that is what the trim system does.
If your LB is working well with subtrim I would use it.
The general rule for a 3 or 6 axis gyro is not to use any subtrim or trim
but I see many people using it without any issues. I have tried it also
and it worked fine.

I would check for you but I only have one battery for the Hoten X.
Also I have different settings for the Ladybird and Hoten X so I would have to re-bind to fly each one.
I have my sensor voltage alarm on the 2nd sensor set at 3.5V also.

I just had a thought... maybe it's not the sensor but the countdown timer which is buzzing!
Of course when you're looking at sensor view you can't see the timer... I bet it's that!!
Same buzz of course so hard to know!
|Sep 16, 2012, 07:56 AM|
I just found this. It explains what trim system does.
Also see my post #9 above.
|Sep 16, 2012, 08:03 AM|
which one is which. When I was flying I was thinking how can I tell the
countdown timer alarm from the sensor voltage alarm. I have both of them on.
You have the sensor view on so you can't see the main screen to see the timer.
