RE: Interchangable frequency crystals
Ok, Cat! You got the idea. Believe me, once you get a little time in, perhaps a year or so, you will want to go back to the trainer just to "get back to the basics". We seem to fall back on technology (expo, end points, mixing, and so on) with our computer radios. Often, the RTF's we get are basic systems, with analog trims and controls. Nothing digital.
So, when we move into the digital world, we take full advantage of those perks. And that's what they are there for. But, when we reach the point when we want to teach someone else how to fly, we have to go back to the basics and I can tell you that it isn't all that easy for the first several minutes of flying the basic trainer. You find that you are all over the sky, ending up looking like a rank amateur in front of the person you are trying to impress.. rightfully so!!
And there are times when you just want a slow, leisurly, lazy few flighs on something simple and easy, that will float around and almost fly itself. You won't get that with a high performance 3D or Pattern plane.. or a war bird.. but you will with that trainer you saved just for that opportunity.
Good choice.. good decision!!!
