I stated years ago that I was leaving RCU because it turned into the same questions over and over. I think it was the what size prop question that got me. I moved from Vegas back to Calif. And had no field to fly from that was close. I gave up RC in 2015. We just moved to Arizona and I'm in the process of getting some planes back in the air! I have a really nice club just up the road from us! It took a while to figure out how to bind the RX and TX too. Then it has been a chore just to figure out how I did my programs and set up in my old radio. I should be back into flying in the next month. All my engines were frozen so that has been first. Now I need new batteries and a charger. FYI, I still have my CG Extra but I really want/need to recover it!! I'm still on this side of the grass. RCU looks a bit defunked?
