RaGG-e 3inch Titch

RaGG-e 3inch Titch

Ragg-e est une marque anglaise destiné à ceux qui demandent : solidité et personnalisation. Le Ragg-e Titch répond néanmoins à une demande du public d’avoir un appareil plus léger que le WBX5, fleuron de la marque.

Ce build est destiné à ceux qui se posaient des questions. Nous avons franchis le pas pour vous en achetant un exemplaire.

Liste du matériel

Présentation

145mm c’est sa taille en diagonale. On est toujours sur du HDPE (Polyéthylène haute densité).

Le poids reste raisonnable avec 56g.

La première version

Je suis parti sur un kit Emax avec leur F3 Magnum mini et des moteurs 1306-4000kv de la même marque.

Désenchantement total avec les moteurs, il va falloir rallonger les câbles.

Une fois les cables rallongés, j’ai un peu du chassîs pour y placer la fiche XT30e j’ai soudé au combo.

L’idée était de placer un VTX TX25 au cul de la Micro swift. Il impossible de tilter la caméra car elle se heurte à la F3 mini magnum.

Il m’a fallu découper dans le châssis car il n’est pas possible d’y placer correctement la lyre de la caméra Runcam Micro swift.

Après 2 exemplaires foireux de la F3 mini magnum, je suis parti sur un combo HGLRC avec VTX.

Le montage va beaucoup plus vite. Déception pour mon XT30 que j’aurai voulu souder à même l’ESC 4/1. Pas de bol, il est de l’autre côté de ma découpe.

Une petite découpe pour afficher le digit du VTX et une autre pour l’antenne.

Le changement de fréquences se fait par l’OSD

Conclusion

Sur le dernier Ragg-e nous avions été bluffé par la place et la manière dont les choses sont pensées. Sur ce dernier on se demande avec quels typse de composants le fabricant a été pensé cette frame. Car la liste qui est détaillée sur la fiche produit, ne correspond pas.

La caméra se retrouve à notre avis fort exposée. pour le reste, il faudra penser à ventiler au mieux le vtx. Pour le changement de fréquences ce modèle permets le changement par l’OSD via le combo choisit, un must!

Bons vols!

DJI Spark Unboxing & first impressions

DJI Spark – Unboxing and first impressions

Why I bought it?

Being active in the fpv-racing part of the hobby, most people will find this a surprising purchase. Why in the world would I buy a DJI Spark? If you check out my YouTube channel, you’ll find out that there are a lot of aftermovies of fpv-racing events I attend. For me, capturing the event is part of the fun the fpv-racing hobby has to offer. With the purchase of the Spark, I am hoping to find a decent platform to add some aerial shots to my videos. I want to be able to do this without the long preparation some other platforms require and without the risk people getting upset (or in the worst case even hurt).

DJI Spark Fly More Combo

What’s in the box?

Running through the specs of the Spark, I decided to go for the Fly More Combo.
This pack features the following items:

The first thing in the cardboard box is a 16Gb MicroSD-card that DJI included as a gift in the Fly More Combo. It’s a Sandisk Ultra 16Gb card . Then there is the surprisingly small box the Spark Fly More Combo comes in. DJI clearly took a lesson from Apple as the packaging style is almost identical. In the box are two things: the travelling bag and a molded case, together with some documentation.

The molded case holds the Spark, together with the extra Intelligent Flight Battery and spare set of propellers. When seeing the Spark in person, it’s amazing how small it actually is. Although it’s a small aircraft, it looks very decent in build quality.

Out of the travelling bag comes the RC Remote Controller, a bit smaller than the one of the Mavic Pro. Compared to the Futaba T14SG I usually fly, this tiny transmitter feels a bit awkward at first, but I must say it does a really good job controlling the Spark. Then there is the charger with the charging hub which charges up to 3 batteries in less than 1.5 hours (55 minutes for 2 batteries, 50 for 1 battery). The charger also has two USB outputs to charge the RC Remote Controller (USB->MicroUSB cable included) and, if you like, a 4th battery through Micro USB on the Spark itself. The last items are the propeller guards that clip on in under 30 seconds to provide extra safety in situations where needed. They do add 38 grams to the Spark in total.

After unboxing all the items, there is not much more to do than charge the batteries and RC Remote Controller and get ready to get flying!

How does it fly?

First of all, despite its size, it’s amazing how stable the Spark is when flying, even in steady winds. I must say this really impressed me as I didn’t think a small aircraft of 300 grams would handle wind to good.

DJI Spark hovering

I like to take you through some modes and features that got my attention during the first uses of the Spark.

The first is Tripod Mode, which lowers the rates of the controls to make very slow movements. Also, the gimbal control is set to a lower rate to allow precise movements. The ability to lower the gimbal rate outside the Tripod Mode would be a welcome addition as it feels a bit to fast in general.

Active Track is another great feature that tracks and follows a person or object without the need of manual control. It can even automaticaly circle around the person or object while following. Adding the Obstacle Avoidance feature into the mix, this feature is quite safe to use if you keep its limitations in mind. The Obstacle Avoidance feature only sees what’s in front of the Spark. So when  you set it up to follow a subject sideways, keep in mind that won’t stop when an obstacle is on the left or right of it.

DJI Spark RC Remote

In Sport Mode you get a lot more speed out of the Spark, which is nice when shooting footage in a big area in a small amount of time. Sport Mode is easily selected by sliding the Sport slider on the RC Remote Controller to the right. The gimbal will follow the roll input when cornering, but stays level when moving straight forward or backward. When you can’t take-off in the proximity of your subject, Sport Mode can get you fast to your destination. You can then quickly change back to normal mode and shoot at a lower flying speed.

The Quickshot Modes are nice if you don’t want to waste time to manually shoot your footage. You can simply select a person or subject, tap the type of Quickshot you want (Dronie, Circle, Helix, Rocket) and press Go! The Spark will start the selected Quickshot and create a 10-second clip and return to the starting point automatically. Although I didn’t think I would use these automated shots, they come in quite handy.

The last feature I really like is the possibility to point the camera straight down and take top-down shots like this one. This might not sound like an amazing feature, but considering the size of the Spark and its gimbal, it’s really nice that it tilts all the way down to make top-down shots.

Those are the 5 features I like the most about the Spark so far.

I will continue to use the Spark for different projects and will report back with an update after some more experiences with this great little machine.
