I currently have three extra receivers. I also have a Spektrum DX18 TX, a new, more capable transmitter. I think I will use the three extra Hitec receivers that I have and keep using the Aurora 9 for as long as I can. I will start migrating Spektrum receivers into future planes. I like to think that Spektrum will be around for awhile. It is hard to believe that I have had this Hitec radio for 10 years now. I have gotten my money's worth out of it. I would like to find stronger gimbal springs for the Hitec radio if anyone has ideas on that. Let's see what Hitec says about receivers and support for the 9 after they get back from the new year break.
