I just did a quick search to find that page. I was not sure if those were the only choices available to you. I thought you might be able to search the site and find the proper adapter. I have used Futaba for years, so I am familiar with the Round DIN and the Square connectors on Futaba radios. I still have the Round to Square Trainer Cords. I thought JR/Spektrum were the only radios that required batteries in both the Master and the Slave. It sounds like you have to be careful since the A9 operates at a lower voltage.
