TEST: Tovsto Aegean

null

INTRODUCTION

Here is a basic 350mm brushless AP machine where the price will be the massive/main argument. With the Tovsto Aegian you have a basic GPS machine equiped of a gimbal port to attach eventually a gimbal. Let’s discover the bundle.

BOX CONTENT

null

+ 1 x Tovsto (with a 3S 2200mAh LiPo with XT60 connector)
+ 1 x Transmitter (using 4xAA batteries not included)
+ 1 x Charger
+ 1 x Camera mount
+ 3 x Allen keys
+ 1 x Bind plug
+ 1 x Instruction manual (English)

OVERVIEW

The design is ultra classic, largely inspired from a DJI Phantom. The Aegean comes in black.

-FRONT VIEW
The front side welcome the battery bay

The battery bay

null

With the battery inserted

null

In practice, without any modding, it will be hard to insert a larger battery. Maybe a 1cm and 0.5cm taller can be attempt.

-SIDE VIEW
null

-REAR VIEW
The rear side welcomes the LEDs status

null

As you can see, you have to wait the main status LEDs becomes yellow to have precize GPS hold and RTH.

null

Below the triangle sticker, you can find an hidden microUSB plug

-BOTTOM VIEW

The 2.4G antenna

while the compass is also external

null

A mini gimbal port is available: a JST plug delivers +12V and a servo plug to control your pich/roll

null

The M2 holes to eventually attach a gimbal

null

null

But in practice the ground clearance is limited to instally any gimbal

Motors & Props

Some large 9450 model selftighting, like DJI phantom model

null

null

It won’t be really possible to install some 10″ model. the clearance is already very small

null

Motors are classic 22″ model

null

null

LiPo

A 2200mAh model…. Without gimbal, you can expect 15min.

null

Disassembling

null

Surprizing, the GPS module is not shieldied.

null

null

Good news, the receiver is nothing else than a FLySky AFHDS-2A model

null

null

Insert the bind plug if you need to re-pair the Tx with the Rx

null

The flight controller board is boxed

null

But when you connect the aegean to a PC, a new device is opened with “ATmega 2560” mention. It means that the FC has a 8bits MCU like APM boards. I tried to connect to Mission Planner or Multiwii without success.

On the main PDB, you have a buzzer

null

Transmitter

A large central RTH button and a pot to control eventually one gimbal axis via the servo plug. The transmission range should offers more than 500m but the geofence won’t allow more than 300m.

null

The right should swith indication are not correct. In practice, you can choose: manual, altitulde hold and GPS hold flight mode respectively
null

No headless mode as indicated

FIRST USAGE

Before take off, be sure you are fixing enough satelittes and the LEDs status becomes solid yellow. To arm the machine, you have to be in manual flight by preference.

As you can see, the GPS hold stabilization is far to be perfect. It’s a real pitty there is no known way to perform a compass calibration. Maybe if one day the ground station software will be available but I am really doubting of its release. Even in manual mode, the Aegean is not super fast and in GPShold, the max speed seems limited to 15km/h maximum. RTH seems ok and you can engage it in any flight modes as soons as your fixed enough statellites at take off.

CONCLUSIONS

The Tovsto Aegean is in fine far to be an outstanding machine. The lack of ground station software, the introduction of the 300m limitation and the relatively poor ground clearance limiting the gimbal mounting represents for me the most limiting factores. More, the stability is also far to be perfect. The 2200mAh LiPo is not strong enough to carry a gimbal cam rig during more than 10min. So if you plan to grab this machine, the landing gear and battery bay modding will be the must to do immediatly.
