GPToys Aviax H20 Review (in progress)

GPToys Aviax H20

Description:

Introduction-
Purchase Link- $39.99 (with coupon code WGH20) http://shrsl.com/?~9al9
The H20 Aviax appears to be almost identical to the GPToys Aviax model, the two models share all the same features such as headless modes and cruise control. The primary difference between the two models is that the H20 is advertised as being "Waterproof". Now before we go any further I want to note that the manufacturer claims the control board and the motors are waterproof, they make it a point to state that the battery is not waterproof. Based on this statement and my own personal experience I would say that completely submerging this model is not a good idea.

Specifications (as tested)-
*Note- all range testing is performed as a horizontal walk out, distance measurement is performed using a Bushnell scout 1000 rangefinder

Frequency- 2.4ghz
Battery- Quadcopter 650mah (2 included)
Transmitter 4x AA batteries (not included)
Flight time- 6:00 WITH prop guards
6:15 WITHOUT prop guards
LVC- 35 seconds
Charging time- 1hr with stock USB charger
Control distance- Dropouts starting at 155 meters, complete loss of signal at 160 meters

Unboxing

Transmitter

Description:

The H20 Aviax features a full size WLToys style transmitter which happens to be one of my favorite style toy grade transmitters to fly with. The transmitter features a large back lit LCD display allowing the operator to quickly determine what rates they are in, how much trim has been added, and whether the LED lights are illuminated on the craft or not. The shoulder buttons are easy to reach without taking your eyes off the craft, however the buttons along side the LCD are not as easy to reach and are not labeled. Since the cruise control and headless mode buttons are very close in proximity it is very easy to accidently hit the wrong button with unintended results (typically getting stuck in a tree )

Quadcopter

Description:
The H20 Aviax has a sort of mini Phantom look to it and features a faux GPS dome mounted on top, although most of its design features appear to be based off of the popular Syma X5.

At first glance the included prop guards seem as though they would work great, however in testing I found that they are very flexible and will actually hit the props during a flip causing the quadcopter to crash.

One great feature of the H20 Aviax is the quick change prop design, simply pull the locking pin and the prop comes right off. I am amazing that more companies are not using this method.

Description:
The LED lights are very bright with red in the front and green in the back assisting in orientation during both day and night flights. Since the body is painted silver the LEDs don't shine through the arms making night flights difficult, I have not tested the orange body so I'm not sure if the lights shine through any better.

The battery bay is definitely styled after the Syma X5 and gives you enough real estate for a larger battery. Included with the package is two 650mah 3.7v batteries

Features

Headless Mode- The headless mode in this quadcopter works surprisingly well. I found that as long as you did not crash the quadcopter after takeoff the quadcopter would remember its initial heading for the duration of the flight. If you do crash and plan on using headless mode as a "failsafe" be sure to point the heading where you want it and recalibrate the accelerometers.

Cruise Control- Cruise control is an interesting feature, it appears to work as designed but it is difficult to tell because there is no GPS on this model. The way the cruise control is supposed to work is the quadcopter remembers the last 40 seconds of inputs, once you press cruise control these last 40 seconds are replayed automatically. It is important to remember that you still have to control altitude during cruise control and the quadcopter does not have any means of determining where it is in space so it will collide with any objects in its path.

Waterproof- As far as the waterproof claim goes I would say if you are using the standard definition of water proof then no it is not waterproof. I would say that water “tolerant” is a more accurate description.

I did spend some time at the local pond with it and found that if you hit the water in any angle other than completely flat on the belly of the quad the props would catch the water and flip the quadcopter, it would then sink like a stone in seconds.

Description:
When I retrieved the quadcopter from being completely submerged (the manufacturer did state this could be a bad idea) it would no longer power up until it was completely dried out even with a fresh dry battery. I did take the quad apart after and inspect the board and found no evidence of water damage. It appears that most of the shorting was occurring off the main board in places like the LED strips and the external camera plug because with these plugs disconnected the quad came back to life. I think that this would be a good option if you were going to flying around water or snow or even in the rain knowing that if it goes in there will be no lasting damage, but I would not recommend purposely flying this into a body of water.

Conclusion-

Description:
Ignoring the “waterproof” claim, this is a great quadcopter. It may not be lightning fast but its smooth easy to fly style and long 150+ meter range makes this my go to quadcopter almost every day. If you have a friend that wants to get into multi rotors the Aviax H20 would be a great place to start. The only Cons that I can see is that it is on the slow side and the prop guards induce more crashes than they prevent. All things considered I would definitely recommend this quadcopter.

Pros-
Long range
Smooth stable flight
Usable headless mode
Water “tolerance” reduces risk when flying around water
Easy to change props

Cons-
LEDs don’t shine through body
Prop guards are not effective

It may not be completly submergable underwater , but if it can fly in the rain
then it can do what others cannot. This allows flying on days when it would normally be rained off.
That makes it very interesting.

took it for another spin, and I must say it is a lot easier to fly than the some of it's peers, regardless of waterproof or not, I think it would have been just a great beginner quad alone. Not so keen on the props design, but just the right size for my old pair of eyes, great for practicing flying in circles or in 8s.

here is great overview from Leo & team. more at playlist

My dad got me this quad for my birthday. I've got 6 batteries through it now and i absolutely love it! It's super stable and very smooth flying. The body is quite tough and the ends near the motor remove separately from the body making a motor swap a piece of cake. The lalanding gear is really stout and just pushes in with no screws required. If you don't put on the useless prop gaurds you can just push the optional landing gear on (it will sit on the motor gaurds without the landing gear on) charge a battery and fly this. Flies great in the rain and sounds cool when the blades chop the raindrops. This is an awesome quad and a great gift for sure! Would also make for a great camera quad. It will also do flips just a couple of feet above the ground which is impressive.
