If someone wants to know how to put together a Trex helicopter, I can give them a list of parts and instructions on how to adjust everything, NOTHING is left out - I can give you ALL the info you need to build that helicopter right, and how to check to make sure it's right. Information like that for FPV is rare, and just when you think you've found it, other information says that information is wrong. It's very confusing - it's like a giant brick wall in front of beginners. I'm pretty darn smart and I am so frustrated with it right now that I'm waiting until winter and then I'm going to be doing ground-based FPV until I'm confident with my system.
The problem is variables. For conventional RC flight the list of variables to go
wrong is lower so there's a larger error window. For FPV there's so many
things functioning together in unison that the error window is small. When
you have systems working together with other systems you're greatly
complicating the relative freedom you have to make errors. Take your trex
helicopter example, you can tell someone exactly how to assemble it
because the number of variables is low. You can tell them the proper
assembly and the way to check to make sure its assembled correctly
because there's only so much that they could do wrong. With FPV you can't
do that because, unlike the helicopter, the performance not only depends on
the plane itself but other variables as well. With FPV you have to consider
not only that everything is put together correctly, already hard when you
begin to complicate wiring with more and more components, but how these
components interact with each other. And that's just the plane, you
still also have to consider other things like what the RF environment is like
where the plane is flying. When you sum it all up, the exponential increase in
things that you have to get right (variables), compared to normal RC, is why
it's all so difficult. The only way to solve this problem is to actually do hard
research on what you are doing. It's not easy and should never be
advertised as so. You have to know a wide range of technical skills to
really get inside that error window that allows for truly successful FPV flight.
