We got 4400 milliamps onboard the plane and we have 6000 milliamps on the external foambox wich holds the two hi res. cameras and a GPS tracker.
On the way up the external box will be used as a powersource.After disconnection the 4400 milliamps aboard will be used just for decent.That is more then enough.
The videotransmitters will do the heating inside the plane.There will be 2 of them,connected with 2 antennas with 2 different orientation.
So transmitter 1 will be used for accent and transmitter 2 will be used for decent.Both of them will be monitored heatwise so if any of them overheats/no aircooling because no air/no problem it can be switched over to the otherone.The transmitters are 1,5W bought from Readymade rc.Vid. antennas aboard are a Vee dipoles.
At a groundstation 4 RVOSD receviers,4 32Db gain preamps,4 16Db helical antennas all of them linked to 4 separate monitors,no diversity will be used.
