RE: Camera/Transmitter/Receiver Package
What type of a plane are you using jjmav?
I have a 600mW system from blackwidowav and it weighs 50 grams with the panasonic camera and a homemade power cable. Add 1.5oz for lithium battery and voltage regulator, unless you use the planes battery for everything.
With the proper receiver antenna it should make it that far easily.
