I guess it depends on what your definition is of "correctly".
Learning to fly with a nitro trainer I suppose is the only correct way to learn in your opinion.
I'm telling you from experience that you can get your foot in the door for a lot less.
I started in this hobby with an Aerobird for less than $200 bucks. I learned to fly it on my own. Went through a few wings. And than I got addicted to RC!
Without getting all "touchy feely", lol, [&:] I guess you could say that Aerobird changed my life. It got me addicted to RC and then I saved for a nitro trainer and joined a club.
But if someone told me up front, you can't get into this hobby for under 3 or 4 hundred bucks I would have said no thank you.
Try to be a little open minded here. This wonderful hobby is full of tons and tons of possibilities which are expanding everyday due to advancements in technology.
There is more than one way to skin a cat! And it doesn't always have to be dropping 400 bucks to get started.
