Welcome to PoA! Awesome that you started flying, congrats!
I don’t feel like I have any kind of foundation at all.
That's probably the core issue, without a foundation it is hard to really learn anything. Have you done any ground work with your CFI or has it all been in the air? I ask because, personally, I find most many of the aviation online courses mediocre at best, and a complete waste of time at worst. The best foundation will come from just having a chat with your CFI.. doesn't even need to be an official pseudo classroom thing, just a back and forth chat about being a pilot and airplanes. If you can get a core foundation down through a discussional format with her or him I think that will help you. There are some cool YouTube channels out there as well about flying, not necessarily to
learn from, but to start building that "this is what flying a plane is like" foundation
My instructor has taught me a lot but when it comes to performing, I stink! I either freeze up, manhandle the controls, or flat out just get angry and shut down.
Well, you are only 5 hrs in, so you have to cut yourself some serious slack. With flying you'll learn early on to NOT get lost in your head.. even though it can sometimes feel overwhelming, especially in training. When you feel yourself freezing up, or manhandling, or getting angry, etc., what is the first thing that causes that? I ask because, depending on what causes you to come unglued can have an impact on the best way to overcome it
--for some people that's fear of stalling / crashing / wings falling off / death so they freeze up or panic and overcompensate. Best way to get over that is to let your CFI do some maneuvers and get comfortable in the air. Since you work in aviation currently I doubt this is you, but I pose it as an example
*if you can figure out the root of what it is that causes things to unravel then that might help find a remedy. From the sounds of it, you might just be holding yourself to a standard that is too high. Holding yourself to high standards is
good, but not if you set the bar so high you can't cross it and then you just get frustrated
Any suggestions on how to better build my foundation? Or is it just a dive into the deep end and figure it out process?
Other than what I wrote above, you *could* try going flying with a few different instructors, or even go up as a passenger with another local pilot. Not saying there is anything wrong with your CFI, but learning to fly involves spending a lot of time with one other person, and it's expensive and challenging, so it's important you find a CFI that is a good fit for you. Might also just help seeing how other people fly, etc., to help you get more comfortable from a pilot's perspective and being up in a small plane
cheers and happy flying!
