Long flights!

Summary: The TIANQU XS809W is a folding WiFi FPV quadcopter featuring flip mode, headless mode, a 0.3MP camera, and 10-11 minutes of flight time. It's a fun portable flyer and is definitely worth taking a look at

Pros:
  • Portable
  • Long flight times
Cons:
  • WiFi app doesn’t work very well
  • Deadzone on transmitter throttle

Get it for $50.54

Thanks to Gearbest for sending me this sample to review.

Flight Performance

Flight performance on the TIANQU XS809W is pretty good with nice stable hovering and a great amount of control.

There are 3 different speed modes with this quadcopter with the lowest being okay for windless conditions but with any amount of wind you’ll want to be in one of the 2 higher speed modes.

In the highest speed mode this thing moves around decently fast but I feel like it could definitely be a little bit faster and a speed level above the third would be great. I also think that while the yaw is adequate it would be better if it was a little bit faster.

As far as the hovering goes as I talked about it is nice and stable with very little throttle adjustments being needed to hold a constant altitude.

Flight times are great on this quadcopter with about 10-11 minutes of flight time on average and the quadcopter automatically lands when in LVC mode.

Flips work great on the TIANQU XS809W and they’re very tight with a nice recovery after the flip.

Headless mode and one key return perform perfectly fine on this quadcopter so long as the heading is set properly when taking off. Not a huge fan of these modes but I was able to spin the yaw around while moving which was lots of fun.

When landing and taking off you have to be careful to account for a small deadzone in the throttle of the transmitter which makes you throttle down quicker than you might expect.

Design

Taking a look at the overall design of the TIANQU XS809W it comes in black with yellow accents, LEDS in both the arms and front of the quadcopter, and features nice folding arms for portability.

One of the major selling points on this quadcopter is going to be the folding arms that I mentioned and I have to say that the folding mechanism they came up with works pretty well.

When the arms are extended they lock into place through pressure rather than a locking mechanism, this makes it crash resistant as the legs will fold in on a crash rather than snapping.

 

When actually folding the quadcopter for storage you do have to make sure to fold in the back legs first otherwise they will stick out rather than folding neatly.

This quadcopter utilizes a geared motor system with exposed gears on the top of each of the arms. The geared system is not a bad design in itself and works nicely but the gears on the TIANQU XS809W are exposed to the top leaving them open for debris to get caught in.

On the back of the quadcopter you have your battery compartment which your battery slides into before locking into place.

The battery itself is housed in a proprietary plastic shell design and while it fits snug with repeatable performance you’re also reliant on the company for spare batteries. To remove the battery you press down on the release tab which you actually have to press rather hard in order to make it release.

On the bottom of the quadcopter they also have a power switch which lets you keep the battery inserted while in storage.

Camera

The camera itself is 0.3MP and transmits video over WiFi FPV to an app on your phone which is where video is also recorded. It’s mounted to the front of the quadcopter with a slightly adjustable angle and can also be angled upwards if that is wanted.

Since video is saved on the phone your resolution is 640 x 480 and video quality is entirely dependent on the signal quality between phone and quadcopter.

The camera module they’re using has a pretty narrow FOV so you can only see what is pretty much directly ahead of you.

There are a few issues when actually recording and you can read more about them in the “Phone App” section below.

Transmitter

Taking a look at the transmitter for the TIANQU XS809W it fits great in the hands, has very cleanly labeled buttons, and includes a built in adjustable phone mount.

The feel of the controller is very nice and is about the size of an Xbox controller with the flat style thumbsticks and general shape.

As I mentioned the buttons are cleanly labeled with buttons for flips, speed changes, headless, one key return, and an emergency stop button.

Trim buttons are on the left side oddly enough but they are there and work fine if you need to adjust for drift.

This quadcopter does feature a failsafe should it lose signal from the transmitter and automatically shuts down around 5 seconds after losing signal.

As mentioned above the throttle stick has a little bit of a dead zone around 10-25% which makes landing difficult and makes flying it a little bit difficult to get used to.

Phone App

The phone app for the TIANQU XS809W is what I think is one of the major flaws in this quadcopter for multiple reasons.

First off the app just has the tendency to crash completely when doing things like enabling video or the on screen app controls. Secondly when you are flying the video itself has very high latency, freezes occasionally, and sometimes the video will just randomly stop recording.

My third problem with the app is the spotty controls, occasionally the on screen controls will stop responding and if you’re moving in a tight situation this can result in a crash.

The last thing is more of an annoyance rather than a problem but you can’t use the on screen controls while the transmitter is turned on.

Final Thoughts

Overall the TIANQU XS809W isn’t a bad flyer and while it does have a few flaws is still a perfectly fine flying quadcopter.  The portability function works great although but the WiFi FPV isn’t the best so if that’s important to you it might be worth looking at other options. Flight times are fantastic and if you’d like to pick one of these up for yourself you can click the button below.
