Let's build a FPV drone: frame
Many say that small 250 class quadcopter are super fun. Small, fast, agile, tough and crash resistant. I've decided to check it out and build 250 quadcopter drone by myself. And next few posts will be tightly connected with this topic. Let's call it a build log.
The most important part of every multirotor is a frame. It decides about everything. For my quad I've decided to use ZMR250 clone frame made from carbon fiber.
There is also glass-fiber version of this frame, and it's half a price (below $20 while carbon is around $35). So, what do we get for additional $15? We get 2 good things, and one bad. But let's begin with good things:
- carbon fiber is lighter than glass fiber. My frame weights 145g while glass-fiber equivalent weights 181g. 36g might not seem much, but it is a difference after all. In my oppinion a difference worth $15,
- carbon fiber is more durable than glass fiber. At least in theory. So, in theory carbon fiber quadcopter frame should be harder to break during crashes. We will see.
An the bad thing? Well, carbon conducts electricity and can block radio waves. This means, that you have to be extra careful with all the cables and antenna placement. Insulate everything, never leave any cables touching the frame and antennas has to be placed as far from frame as possible. Some kind of mast would be recommended.
