Check with your local club, they may have a club trainer that you could "knock the rust off". We had a very similar situation in our club just a couple weeks ago. A guy that used to fly 16 years ago came out and had a foam Cessan 182 with him that he wanted a trim flight on. He was really worried about flying it as he was afraid his skills would have been all gone. Luckily I had one of the club trainers with me so I pulled it out and put him on the buddy box. By the second flight he was completely comfortable in the air and needed no help from me. The skills that you developed the last time around will come back pretty quickly. If you can get some time on the club trainer it will let you know right where you are, either you will need to get your own trainer and spend time getting back into it or you will come back right away and find you won't need the trainer.

Hope this helps
