Stick with Mode 1. I also stopped flying RC around 1980. Started back up about 10 years ago. I'm glad I stuck with Mode 1. I felt like I was flying as well as I was in 1980. The new radios are fantastic. The radios can be bought set up on Mode 1 or they can be easily converted to Mode 1. I fly a Futuba 18sz now. If I would of had this radio back in the 70's I may have won a few pattern contest.
