That's good advice from Chellie and it sounds like you are progressing well. Flying the size of model you are is actually more difficult than flying larger models. Larger models are obviously easier to see and tend to fly/roll slower so are easier to fly.They also fly better in wind and don't tend to be influenced by air currents as much as smaller models. Your motor/esc setup will cope easily with 60 inch wingspan models up to 2.5-3 pounds weight so there are loads you can choose from. Just remember not to try to run before you can walk and I'm sure you will have lots of fun.
Good Luck.
