Martian 2 Beginner Build

I am building this quad for my brother. I want to throw away the included PDB (stability issues when using only the fiber glass plate?) and use a Matek or GEPRC PDB like this one (https://www.banggood.com/GEPRC-XT60-PDB-5V-12V-Dual-BEC-PDB-with-LC-Filter-for-RC-Multirotors-p-1154841.html)

I would like to use a 4in1 esc but since I started out with a x220 wizard two months ago I saw how easy it seems to burn a ESC as beginner and the easyness to replace it when using single ESCs. Since my brother has no FPV experience and will likely crash a few times, I want to be able to replace the ESCs quick and cheap at 7€ a piece (https://www.banggood.com/Racerstar-RS30A-30A-Blheli_S-OPTO-2-4S-ESC-Support-Oneshot42-Multishot-for-FPV-Racing-p-1063907.html) Are the V2 really worth 15€ more?

As for the VTX, I am currently deciding between the VTX03 and the TX526. I think I will go for the TX526 since I have the 12V on the PDB anyway and I can use the aomways which I planned to buy for his VR007 Pro goggles anyway - also looks more "professional" if you ask me and worked pretty nice on my own wizard.

Not sure about the motors, but something cheap from racerstar. 2205 2300kv but maybe I will test out something better.

You might want to look into the newer BLHeli_32 ESCs. They aren't much more money and you can run Dshot1200.

Traviak Jul 29, 2017

Do you think it's noticeable for a total beginner? The ones I found are more than double as much as these are.

Whiffles Jul 30, 2017

It's probably not too noticeable for a beginner, so you should be okay going with the budget ESCs to start.
