I recently reviewed one of the best RC helicopters for beginners, the Syma S107 Blue (I love color blue), this helicopter is perfect for newbies since it can withstand most crashes and the price is excellent, it comes fully assembled from the manufacturer and it is ready to fly out of the box. I am always looking for other ways to improve a great experience so I spent some time last week researching and found that the main complaint about this toy is the short flight time, which is due to the battery that comes installed from the factory, and after digging for a while I discovered that actually you can upgrade to a superior battery cell and thus increase the flight time, the process is not complicated at all but will require a soldering iron since the battery is soldered inside the Syma S107 RC helicopter.
As I was telling you, the battery cell is soldered to the PCB of the RC helicopter; a pair of wires is used to connect the battery to the circuitry of the PCB and in order to replace or upgrade the battery some tools will be required:
- A bench to work
- New battery
- Soldering Iron
- Precision Knife
- Scotch tape
- Jewelers Screwdriver set
I assume your intention is to do the job by yourself (otherwise you won’t be reading this right?) so it is important to mention that you need to have a basic understanding of how to use solder and a soldering iron, these tools can get over 400˚F of temperature, so it is important to be careful when using this tool.
The easiest steps to replace or upgrade your Syma S107 RC helicopter battery
Here I will present you the basic steps required to replace or upgrade the battery cell, I will include a video from a guy who I think does a fantastic job so that way you can have a better understanding of what to do.
Alright! Let’s get our hands dirty! (So to speak)
- Remove the Shell: Using the jeweler screwdrivers remove both screws on the sides of the helicopter’s shell, this will give you access to the internal circuitry, be careful to not pull it strong since there is a wired LED attached to the shell.
- Dismount the battery: The battery is mounted on the helicopter with tape, so just remove it by pulling it from the mounting surface.
- Cut a slice in the insulation of the old battery: This will serve for you to use the soldering iron and remove the soldering from the wires.
- Remove the soldering from the old battery: Do this at the union of the battery and the wires. A good tip here is to mark your old battery if it still works so you can use it with another toy or as a replacement.
- Cut a slice in the insulation of the new battery: This will be useful to solder the wires of the old battery to the new battery.
- Remove the wires from the new battery: These wires will not be used, so it is a good idea to remove them and save them for another battery. Remember to mark the positive and negative ends of your new battery.
- Solder the new battery: Attach the wires of the old battery to the new battery and solder them.
- Insulate the wires: Add a small piece of scotch tape to insulate the soldering.
- Mount the new battery: Put the new battery on the mounting surface.
- Assemble the shell: Put the shell back on the helicopter using the screws.
