TEST: GPtoys Aviax H20, a waterproof miniquadcopter

null

INTRODUCTION

The GPtoys Aviax H20 is a miniquadcopter offering two features: i) a waterproof capacity and ii) a new “cruising” mode, replaying you last 40s of your flight. If the quadcopter is assumed to be waterproof, no waterproof camera module is proposed.

BOX CONTENT

+ 1 x GPtoys Aviax H20 (with a 1S 650mAh LiPo with microLOSI connector)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x USB charging cable
+ 8 x Spare props (4 CW, 4 CCW)
+ 2 x Landing gear
+ 1 x Instruction manual (English)

OVERVIEW

A classic X design with a fake GPS dome on top. The orange color is present everywhere, IMHO the best color to localize a lost machine

The LiPo occupy must of the free room limiting the choice to installer a larger model.
No powerswitch….

-Weight

126g for the minimum configuration

and close to 140 for the full configuration

Motors

Some 8.5mmx20mm coreless motor are installed. Beware, they offer two tiny holes (for cooling themp). In practice, if you want to fly the Aviax on sand beach, grains can entered from them.

null

No ballbearings are installed but only some 3mmx6mmx2mm bronze bushings

LiPo

A 650 mAh 1S LiPo with a microLOSI connector and 25C as discharge rate

Disassembling

null

a LT8910 as 2.4G RFchip. This model uses a very low datarate for transmission IMHO more adapted for RC transmission. In practice, the control range is pretty good. You can reach 100m without any difficulties

Transmitter

A classic chassis with two bumper bottons, four panel ones. The left bumper engage flipping, the right button cycles between the four speed modes: 40%,60%,80% and a 100%. Notice the yaw rate is slightly proportianal to the speed mode but generally slow versus other rate. The top left pannel button engage the “cruise” mode replaying the last 40s. Since no compass, barometer are included, this feature is strongly dependent of the initial point and the wind conditions. It can work more or less correctly in very light wind conditions. Expect important drift if not. The lower panel button turn on the Headless mode. The top right turn on/off lights and the last bottom right the camera module. To calibrate the gyros you need to press both stick in lower outter positions

FIRST USAGE

Waterproof demo

CONCLUSIONS

A classic miniquadcopter size, with rates more targetting beginners. Super stable machine with a good radio range out of the box, a potential first machine to carry a lightweight camera module (around 20g of payload capacity). The waterproof capacity is limited in time (fews seconds before to flow) and requires calm water. For beach usage, you will have to clean motors/gear system carefull to remove salt/sand. The cruise fonction requires also some calm wind condition to “rewind” more or less correctly last controls.

UNBOXING

PROS

+ Very stable quadcopter
+ Adapted for beginners
+ Can float few seconds onto water
+ Good control range (approx 80-100m)
+ Orange color
+ Spare battery

CONS

– Lack of vertical power
– Slow yaw rate
– No wind resistant
– No ball bearings
– No real floating capacity in water
