Hi Sven and welcome to RCU!

Long post, lots to digest. To begin with, have you set a budget? You said you want to begin with electric. Is your choice of electrics based on cost, quiet flight, being able to fly in smaller fields, because you think they are easier, or just because you like the idea of electrics? Electrics are a great choice, many people fly electrics and love them. Something you'll discover is that this forum tends to have more people who have glow planes, so it's not uncommon for people to recommend glow trainers, even when people say they want electrics. What we've often seen is that a person hasn't considered all the options, so getting different opinions helps them understand the choices. If you haven't had a chance to see anyone , I encourage you to find some of the local clubs and take a look.

Only after you've chosen what kind and size plane you want to fly should you try to narrow down your radio choice. Also, in spite of the trend you see here toward recommending more and more expensive radios, a 6 channel radio is not a "must have". Many people have learned on less expensive radios, and have continued to enjoy the hobby without "jonesing" the more expensive radios.

So, go see some of the local flying and then check back in with your thoughts.
