I dont know anything about the FMS software but I do reccomend the great planes simulator. I was out of the hobby for 15 years and it helped a lot to familiarize myself using the simulator. Hey if the software is free it cant hurt to try. In any case welcome back. I dont know where you are from but all of the clubs I have been in were in the city. Theres a lot of experience there that can help to aviod costly mistakes. It my well be worth the extra effort to find an experienced instructor. I'm not saying you CANT do it on your own, Its probably less expensive to get someones help. Besides glow powered planes can be pretty quick compared to a park flier.
