If I taken the roughly $100,000 I put into every conceivable STC on my old piece of shit 170-B and just simply flew it, I might be a fairly good pilot these days, instead I have a beautiful airplane, but am still a piece of shit pilot.
I see this thought from time to time, and am pretty much guilty of doing the same. But have a different feeling about the results.
At the time of getting into backcountry flyng,6-7 years ago, I got severely bitten by the "bug, to fly backcontry". I read everything I could find about it. Talked to anyone I could that I thought had an abundance of knowledge about the subject. Had a pretty good income at the time(luckily, but that's gone now
Now I am well aware of the fact that it doesn't matter what you fly, or how much you spend modding it, it doesn't make you a good pilot, but there sure is nothing wrong with having a good platform to learn from.
Now, did I need to do this? No. My plane would go into most of the places I go without the mods, but now it can do easier, with a larger margin of safety. So, if you can afford it, why not have a well maintained, better performing, safer plane.
Experience is the only thing that will make you a good pilot, and the more the better. Everything else is tools, hopefully to make the learning experience easier/safer. I have been flying as much as I can afford since then, practicing what I have been taught, and learning new skills.
I also felt that I was getting older, and didn't want to spend 10 years(?), hopefully learning to do this. And who knows how many costly mistakes I would have made$$$$
I know that that I still have a lot to learn, and I am looking forward to it. That is why am here. But, I am happy that I can go into most any strip out there, and be comfortable and safe doing it. There is nothing I would rather be doing. Just wish my income would come back so that I could do it more
That's my story, and I'm stickin to it
