Big Motor Mod H107L-8mmod= super fast micro

So your ready to upgrade your Hubsan X4 H107L (black one) to have the fastest micro quad on the block, that is unless you live on our block 🙂 This is not for beginners as it is extremely fast, but if you are ready…
Upgrade the H107L with the bigger 8mm motors for the H107C/H107D and ditch the prop protector.


On our chopper we made good use of a Cali-Bros business card and placed it in the hole where the camera goes to give it a cleaner look.
You will be amazed at just how fast this thing is “it’s dangerously fast and even more fun”. Chicks dig the white body too j/k.

Parts List:
4 X 8mm motors for H107C/H107D
H107D Body

You will need to un-solder all the motors and LED’s and then re-solder them once the motors are installed on the new body. If you have an older model without LED’s you will be happy to find there are LED ports already on the board. You will just need to buy some LED’s. The H107L has no problem powering the bigger motors. The screws and rubber feet will work on the H107D body.
It looks possible to modify the H107L body to fit the bigger motors, but we haven’t tried it. Please share if you have tried this!

The prop protector is totally worth it when learning because it will save your props and motors. If you fly without it; where glasses, don’t fly around children or people without glasses, caution around TV’s, and have lots of extra spare propellers. While the prop protector doesn’t completely protect from injury it does help and will also save you a ton of props.

If you haven’t soldered motors this soldering video should help.
Here are some soldering tips:
* Use flux “a dab will do ya”
* Keep it steady and provide good contact
* Add fresh solder just before each solder (remove excess)
* Most importantly, hold the wire so that it stays down after you lift the soldering iron
* Don’t overheat the board (if it doesn’t melt in 5 seconds you probably need: flux/fresh wire/better contact/steadiness) it’s probably not the temp.
* The solder should look wet when you are done and [b]not beaded[/b] up like water on wax. Be careful not to move the wires for the few seconds before it solidifies.
