[Question] What's the max/min value of rc channels?

[human890209]

Hi,
void setRcChannel(uint8_t index, uint16_t value);
Q1: What are the channel values for the min, center and max positions of the stick? Are they 1000, 1500 and 2000?
Q2: What are the stick mode of the channel values? Are 1000 the left and down endpoints for the left stick and the right stick?
Q3: Can setRCChannel() use stick-commands to change HDZero VTX and CAM settings just like a quad?
Q4: Can I set VTX's channel blindly (e.g. the VRX is on R8 but the VTX is not, I can't see the camera and the osd menu, but I remember all the stick-command menu) by programming a sequence of stick-commands like the StreetFighter game?
