+
+Technical information about the transmitter:
+* Uses a [YX 4116 21013](https://www.chinaglobalmall.com/products/559732132610) chip.
+* The board is HY-4T69 40M
+* Receiver works on 27.15MHz
+* Transmitter transmits at 29.15

+## TODOS
+* [x] Record
+    * [x] Forward
+    * [x] Backward
+    * [x] Left
+    * [x] Right
+* [ ] Make a cool demo of fine controls
+* [ ] Record a cool trick and make it consistent
