Hello,
I currently have several line of sight RTF quads and am quite comfortable with them. I would like to build FPV quad for landscape/urban exploration (fly in buildings under construction, under bridges etc.) but currently have little knowledge about them. Basically I would like the biggest flying distance and best obstacle penetration giving more weight to the latter requirement probably. So, I imagine I need 1.3 Ghz video transmitter and receiver and 433 Mhz radio transmitter/receiver as they offer most range and best obstacle penetration. Would that be enough to fly through building rooms, controlling quad from outside of the building? Why such video/rc frequencies so unpopular in RTF models if they offer biggest range? Anyone can simply explain difference between various antenna types? What is the difference between clover and dipole antennas? Are there more types and which should I choose? What about choosing the frame? As I understand, the frame does not really matter? It is just how convenient it is and how much inner parts protection it offers and whether there is room for propellers you want? Currently I have my eyes on the popular ZMR250 frame.. Or would something like Phantom frame with FPV system be better? I would also like to have quad battery status, distance from controller, and orientation to controller (circle with arrow pointing towards controller's location) transmitted to goggles, and probably some beeping device on quad so that I can find it in grass. What particular parts would I need for these tasks? What about cameras? It appears that video most often is transmitted to goggles at ~640x480 resolution? What is the limiting factor here? Can I have one camera on quad to both transmit video to goggles and to record hd video to some storage device or do I need two cameras?
I know I can probably find answers for most of the questions by googling and I will continue to do so, but if anyone can provide simple answers to these questions here, it will be appreciated. Thank you.
