Thank you for the reply. So far, I had a couple of Hi-Tec compatible receivers so I just installed them in the planes and programmed my Aurora 9. All seems to work fine and I hope to maiden fly them tomorrow morning as the weather looks good, not a sure thing here! I keep an eye out for a few more receivers. I had quite a few planes and due to my diminishing flying skills as a result of many birthdays, I am able to re-use the receivers in my newer planes. The screen on the T7C is also quite small compared to the Aurora 9, but relearning a different tranny is not high on my list. Will report how the first flights go.
