Since you have the standard Powerpack in the plane, the $45 Xicoy - Jeti telemetry adapter (Dreamworks has them in stock) will allow you to do everything from your Jeti transmitter that you could do from the handheld terminal, as well as get real time telemetry and alarms
Just plug in the telemetry adapter into the Terminal port on the Powerpack ECU and the other end to an EXT port on a Jeti receiver/CentralBox. Done.
The Jeti radio and telemetry sensors (there's a lot of them!) absolutely excels at telemetry ... it's an amazing platform, I'm sure you'll enjoy it.
That color data terminal looks really nice. I didn't see it on their website, I'll have to send them an email and inquire.
