Hi Capn Pete, it is a mine field when you start out decisions that you make now can influence what happens for the rest of your time in the hobby.
1. The mode you fly ( Throttle on left Throttle on the right) choose the one that is most popular in the country you live in. Better for availability of equipment and support.
2. Brand of Transmitter/Receiver that you are going to use, everybody has preferences but any of the name brands are good solid performers, I use Spektrum mainly because of the Bind & Fly models I could buy when I was starting out.
3. A good SIM (Computer RC simulator) again everybody has favorites, most of the free ones are rubbish but the commercial ones start from about $50 to $200+
4. Buy and fly the best you can afford, cheap is not cheap in the long run. I recently met a guy that had given up on helicopter (Too Hard) I invited him to come and fly with out group, when he came he was flying an old Honey Bee and not doing well, when I visited his home he had about 20 helicopters about 5 or 6 good quality Blades & Align I asked him why he wasn't flying them and he said the old ones are expendable I don't want to prang the good ones. He is now flying the good ones and progressing in leaps and bounds.
5. Don't rush it, enjoy the journey, just because your mate flies a SAB Goblin does not mean you have too, get component with what you have before advancing to more expensive models.
I am mentioning these items as they are pretty well a list of the mistakes I made when coming back into the hobby after many years away.
