TwinStar II - FPV setup

The fullHD camera i built in a separable cabin. I cut the cabin in half and built in the camera's mainboard. On the front I glued servo and mount the camera module to servo's lever. The servo is glued angle-wise down.

Camera mounted

From the rear is accessible video link connector

Cam module attached to the servo

Camera is ready

Gyro will (hopefully) stabilize the flight by ailerons. I put it to fuselage in order to be able adjust sensitivity. On the picture you can see the hole that I did because of the possibility of tampering with receiver connectors. The hole is closed by door during the flight.

Overall view of the gyro and receiver, you can see the elevator's servo placement too

Components arrived long ago. Unfortunately the circumstances allowed me to start building until now. I start to build Simple OSD. First I placed all connectors. I placed all of them, although I will not use all from the beginning. Construction should be given maximum attention. First, it is good to solder RSSI input  (I used the connector on the other side of PCB), because a solder point is very poorly available after GPS modul is soldered on place. In between the board GPS module and main board OSD I put several layers of double-sided adhesive tape to make same distance of both boards.

continue until I find some time Wink

Staffed GPS module and all connectors

Connector for AN1 and RSSI

The manufacturer shipped a large and heavy cables and connectors to connect the video from the camera to the transmitter and the OSD. Similarly, antenna and connector of transmitter are in proportion to the transmitter itself huge and heavy. I decided to replace these components. I wrote a separate article about antenna tunning. Now I will confine myself to the fact that I have FPV components built into styrofoam canopy with camera together, to be able to test it as soon as possible.

Everything worked perfectly and the first tests were carried out without major problems. Watch the videos below. A small problem occurred with the OSD. Because data from OSD are sick of seeing in goggless , I wanted to try some settings. I tried to connect OSD to PC using the supplied module, but it did not work well. OSD board become a hot, LED stop blinking and OSD stopped working. I have no idea what happened, yet I have not had time to explore.

Fortunately, OSD is not necessary for FPV flying.

Comparing the size of cables and transmitter.

Final connections, Camera, OSD and video transmitter.
