What do you do when the frame of your Hubsan X4 Micro-quad breaks, and you're either too cheap or stupid to go and shill out the £3.06 for a new one?
The Carrotcopter happens...
'But how does a peasant such as myself make a Carrotcopter?' I hear you cry.
It's fairly simple really, all you will need the electronics from a micro-quad such as the Hubsan X4 or the Blade Nano Qx, a soldering iron, CA glue and a carrot.
Start by disassembling your micro-quad in to its individual components.
You will only be needing the motors, control board, battery and propellers. Everything else can be stored somewhere safe, for when your Carrotcopter starts decomposing because you forgot to refrigerate it.
Re-solder the motors back on to the control board.
Be careful to get to polarity of the wires right, noting this down beforehand is a good idea!
Begin slicing your carrot. You will need 4 arms 5-6cm long, a couple of disks for the body.
One carrot is more than enough for the quad.
To attach the control board use some CA glue to glue a piece of strong tape sticky side up on to the carrot. The reason CA is used is because most glues won't stick to the damp fragile surface at all. CA was originally developed for surgeons to use instead of stiches; hence it glues living tissue very well.
CA Glue will certainly glue you securely to your carrotcopter too, so be careful. If you need help unsticking yourself from a carrotcopter it makes people question your sanity.
Glue the carrot sticks you cut out earlier on to the bottom of the control board carrot in an 'X' configuration, again using generous amounts of CA.
Once you have all 4 carroty arms attached, test the length of the motor cables and cut the carrot to the correct lengths.
Before Gluing the motors on wrap the body of them in masking tape, this will save you covering your motors in CA if you ever decide to go back to the boring old plastic body. I won't blame you, the carrotcopter only has a shelf life of a few days even if it is kept refrigerated!
Cut out a couple of small support blocks from your carrot and glue them, with another carrot disk above the control board to form the battery tray.
It is very important at this point not to eat the carrotcopter. It may look tasty at this point, but resist the urge to take a good bite out of it.
Using the same technique as you did for the control board, CA some tape to attach the battery to the quad.
You're now ready to take to the sky with your new organic carrotquad!
Best of luck building your carrotcopter!
