beautifull yard but it looks much too crowded to fly in, especially for a beginner.
The SIMs you have flown will be very little help to you as far as RC flying.
On the cheap you can download FMS for free but you will need a cable and transmitter to hook up to your computer.
FMS is better than nothing, I went middle of the road myself and bought a used Realflight G2 from Ebay and along with an instructor at a local club the SIM speeded my traing up quite alot.
Number one choice will always be to get an instructor. If you have an instructor you can get by without a SIM.
