Hi and welcome to the Airster TechLab. My name is Christian and today the motto is “I can’t get cheaper”. Let’s have a look at the Martian II 220 from Banggood and what we can expect at such a low price like this. Some try to build the lightest frame while others try to build the cheapest. But if you push the selling price down, something has to fall by the wayside. Either the workmanship, quality or perhaps the design We’ll see what you can expect from such a price and go straight to the key data. Normally you don’t get much for little money. but with 143g, the frame is a heavy piece of carbon where you exceptionally wish you could get less frame for the money. With 220mm motor diagonal it is designed for 5inch props and also 5,1 inch should be no problem. The Martian 2 is an X-Frame in Splitbady Style, that means you can remove the arms which are about 4mm thick and replace them individually. The external dimensions are 24.8cm x 4.9cm x 20.1cm. Now for the price and I have to say I haven’t seen a cheaper frame yet. With 26€ without discounts and those are often available at Banggood, I would say this is one of the cheapest frames on the market. Included in the scope of delivery are, besides the actual frame, a kind of PDB which is part of the construction An XT60 connector, like a few spare screws Basically, this is the same as with many frames. Oh, yeah, I don’t know what to say. This is where it starts. The workmanship is modest, to say the least. The cutter has been tormented and is apparently already well beyond its running time. The layers of carbon begin to peel off in some places and with this frame I would say, before you can use it, you have to do a lot of filing and try to seal the edges with epoxy resin or at least with superglue. The connections usually fit, but this is due to generous hole tolerances. With the quality of the carbon, I can only make my subjective impression and that makes me doubt whether this is real carbon fiber at all. So at the latest with the construction you have to mention that the design has been stolen. A very long time ago, ImpulseRC has released the Alien 5 a popular frame in the USA, which served as a template. So you have to keep in mind that this design comes from a frame that costs $120. And that’s why I’ll start right away with the fact that there is nothing special about this design and it seems almost boring. Base plate, aluminum spacer, top bar, four arms and that’s it. Only the attempt of the enclosed PDB is meant nicely but without 5 and 12 volts BEC just a try. And yes I call it PDB because that stands for Power Distribution Board which means in German “Strom-Verteilungs-Brett” and that’s all this thing does. The XT60 connector, soldered to the PDB, would not last long and should therefore be decoupled from the frame with a small cable. They didn’t copy the mounting for the FPV cam well and made a change. There are now only 3 angle steps and if you want to change an angle, you have to unscrew half the frame. Otherwise, with 28mm there should be enough space between the side panels for most FPV cams. There is no bracket for the actioncam, but there is enough space to mount every possible actioncam and bracket. Because this is a clone you will surely find some 3D printing parts on Thingivers or other 3D platforms. Sometimes I also create 3D printing parts like motor protectors and action cam mounts for the frames I show here But since I don’t know when I’m going to put these parts online at the time of the recordings just have a look at my Thingivers account and you can follow me and keep up to date. The link can be found in the description. I want to make it short I criticized a lot and complained about the design. But you have to keep in mind that this frame costs only 26€. No matter how fast an arm breaks or how long you have to work on the carbon until you can use it. At such a price you can accept almost anything Whoever is completely new in sport, who simply wants to try something out and already counts on the fact that there is a crash, who has time or just wants to try something else. should be told. Buy it yourself you can’t lose much. I am curious how you find the frame and look forward to your comments. I like that you were there again and hope you enjoyed it. If so, of course, I’m happy about a like and subscribe. otherwise tell me what you didn’t like and what you wish for If you have any questions about the frame, please send me a comment or just have a look at our Facebook page “Airster”. In order to stay up to date you can of course follow Instagram, where we always start with upcoming topics. I say goodbye to the Airster TechLab, I’m looking forward to seeing you at the next review and say until then “fly save and have fun”.
