Stratosphere Project

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.

Wow you guys have really thought this through! Do you have any pictures or are you waiting to post them?

So its a mess right now ,but will clear up soon its done.Took me half a day to organise all modules to maintain the CG and keep related things close each other to use less wiring as possible.
There are no connectors will be involved,everything will be soldered to avoid any loosy connections.
A had built many FPV staff ,but this is the first time I have to tag some wires


In the first picture the sticking out cam. lense will have an aerodinamic package to maintain the streamile as possible.

Yea, this is excellent. Obviously not your first BBQ.

What's that tape installed in the frame? Looks like some type of Mylar tape?

What kind of vid transmitter antennas you using and what's they're placement on (or in) the airframe?
