Where to get them ? Well …. searx.me ist your friend (since I don’t want to favour g.0-0.gle).
So how do we start to build a drone ?
Piece of a cake. Put all 4 propellers on a sheet of paper messure what distance needs to be between the center of the propellers. Make sure there is enough space between the blades (no touching pls). For performance reasons I would recommend you to add another half propeller diameter to the distance. Once you are done with it draw a frame onto the paper and transfer it to the PCB (epoxy base mat.). In the end you may get something like this.
Tipp: Some things you may consider drawing the frame: Where do I put my receiver / VTx / FC ?
Once you decided where to put things on your frame and or what your new bumblebee shall look like we cut (saw) it out of the PBC.
Tip:Drilling holes is much easier before cutting the frame out. Make sure you have all the distances and diameters needed and place them carefully.
Next step is to paint and preassemble you frame. Make sure that all holes are drilled. It su*** to suddenly realize you forgot to drill a hole and you have already soldered everthing together. The assembled f(r)ame may look like the one to the left.
Once you tested the frame go ahead attach everthing to the frame and start soldering. I would recommend you not to exeed 350 Deg Celcius soldering temperatur. You may go up the 400 in case you have big ground pads to solder but don’t heat them up for tho long otherwise you will fry the board.
Soldering done ? Everthing connected ?
You might want to :
Check your VTx ( NEVER WITHOUT ANTENNA !!!!!!)
Check engine directions (before mount the propellers)
make sure all screws are tied
Have fun during your first test flight (propellers mounted 😉 ).
