Range Extender: This is the inside of the range extender These are the various adapter cables you will need for modding different aspects of the flight experience of your Vision+ The first three from the left are u.fl to rp-sma adapters. They are used for modding your range extender as well as your controller. The first two are made with RG178 cables, which are better in quality than the third one, which is made with RF113 cables. You will want to get the RG178 ones for better range and stability. The longer one (about 15cm) is what you need for the controller mod whereas the shorter one (10 cm) will suffice for the range extender mod. The second last one from the right is the mmcx to rp-sma adapter, which is what you need for modding the fpv transmitter inside your copter. Depending on where you are going to fit your 2.4GHz pinwheel antennas, cables of 20cm to 25cm long will do. The following is the fpv transmitter of your Vision+. Just disconnect the original antennas and connect the adapters to the fpv transmitter.
