In this report we present the DIY version of the Eachine Tyro99 copter. This is the finished drone model and not the kit, which is a little cheaper but requires a lot of skill.
The kit for the Eachine Tyro99 drone is not for beginners, because some crafting skills, soldering experience and know-how is definitely required.
The kit with all the elements costs not even 90 €!
Anyone with experience can assemble the drone within half a day. If you want to get the kit, we recommend that you get someone to help you with the construction, if you haven’t built a quadrocopter yourself yet.
When the Eachine Tyro99 is finished, it weighs about 330 grams.
You have to keep in mind that there is no 6-axis gyroscope or other additional aids to balance the copter and help you fly. Some skills are needed to keep such a drone stable, safe and elegant in the air. Here applies, practice makes perfect.
Technical data
In general, the Eachine Tyro99 drone is very well suited as a racing drone. The engines run really well with 2150 rpm and with a thrust of 1050g they also have a lot of power.
In our opinion, the camera could be a bit better, but as we all know, the cams of racing drones are never really intoxicating anyway.
Also included is a customized F4 flight controller, whose main control chip is the STM32F405.
Various acceleration sensors are also integrated to improve flight performance.
Design
The frame set has a wheelbase of 210 mm and a frame arm thickness that measures about 5 mm. This frame material consists of 3K carbon fiber and 6065 aluminum.
Overall, the colour design is also very appealing, the metallic orange in combination with the black rubber covers is definitely something to look at.
Of course, the quadrocopter looks like a racing drone, here and there you can see the circuit boards, wires and solder joints, but that is quite normal and racing pilots usually find such a design very appealing. Very distinctive is also the big antenna, in the middle of the rear end of the drone.
Unfortunately, the wings or arms are not so easy to fold down or unscrew in the hand. However, the drone is not so big at all. Due to its compact structure you can take it everywhere with you, a small rucksack or a small bag is sufficient for transportation.
Camera performance and recording quality
Okay, these are no glossy shots, but you can’t compare the Eachine Tyro99 with the usual camera drones, that’s just not what it’s made for!
The cam is a 700TVL CMOS camera with a total PAL pixel count of 1020H x 596 V (about 0.61 megapixels). Here we also have the following video output: 1.0 Vp-p / 75 Ohm and an automatic gain control from 0.25 / 0.5 / 0.75 /1.00 up to 55 dB. You can switch the white balance on or off.
The electronic shutter speed is 1/50 (1/60) – 1/100000 S and the objective operating voltage is 12 volts direct current.
The video image itself looks like from an old TV, it flickers and flickers slightly, but the depth of field is very good for flying with FPV glasses.
If you fly a roll and look with the camera into the sun, the white balance makes the picture black and white for a short time, but after that the color comes back. This can happen with fast flips and is also not so rare with other camera models in drone racing.
All in all the Cam of the Eachine Tyro99 does a really good job and fulfills all the requirements you have for a racing drone. Of course this model is not meant for wonderful panorama shots, sunsets, beach shots or the like.
Receiver module
Depending on the output power, you have different transmission ranges available. Installed is 5.8G 40CH 0mW / 25mw / 200mW / 600mw switchable VTX. Here the ranges in the overview:
- ≥2 km at 600 mW
- ≥1 km at 200 mW
- ≥0,5 km at 25 mW
The module also has an output power self-test function.
How well does the drone fly?
If you fly the drone for the first time, it could be a real horror trip, especially if you have only experience with supported quadrocopter models.
To be able to control the remote controlled model aircraft better, you have to practice and adjust the camera so that you can handle it perfectly. The best setting, which has proved itself here, is an angle of the camera which deviates particularly little from the plane and does not rise too much into the sky.
If this angle to the plane is too big, it can happen that you misinterpret a tilt of the copter from the ego-perspective, which makes flying more difficult.
After a little practice you’ll get the hang of it and can fly over the fields or halls with others.
Advantages and disadvantages
Advantages:
- Very powerful engines for maximum thrust
- Great for drone racing
- This model (DIY) no longer needs to be assembled
- Cool design and stable construction
- Especially for the housing only high-quality materials were used
- Strong receiver module which allows high transmission ranges
- Very compact, can therefore be easily transported
- You can adjust the camera angle individually
Disadvantages:
- Not so good for beginners
- Camera could be a bit better and have an even higher resolution
- You need some flight experience to become really good with this drone
Conclusion
Most drones you can buy in the Racing Quadrocopter sector have to be assembled and flown in by yourself. With the Eachine Tyro99 DIY Set you have saved yourself the most work and get a racing drone with which you can take off immediately.
In terms of value for money, this model is really very good and we can recommend it to everyone. But keep in mind that you need some practice!
