Yes, that’s true that per 4.4 Equipment Functions, a function telemetry link would be illegal in Pattern competition. It would be easy enough to just leave out the telemetry module during competition though. It seems that the intent of the rule was probably to assure that nothing could be fed back from model to pilot to aid their control of the model, i.e., to improve the quality of the aerobatic flight. Electric flyers in particular have been using data logger equipment like Eagle Tree for some time now to get a good handle on pack/ESC/motor performance, but they monitor that after the flight as far as I know. Still, the way rule 4.4 is written, even that seems to be illegal during competition.
The type of feedback you can get from the DX8 seems like fairly benign stuff: battery voltage, signal quality, temperature of something and RPM if I remember right. I’m not sure how any of this helps you present a better sequence, but is certainly useful to help you understand what shape your onboard equipment is in. It might be good to consider amending that rule at some point in the future, and be very specific about the things you are allowed to get feedback on, and for that matter, how you can be informed (audible only, post flight, whatever). Realistically, unless a helper/caller is staring at a display screen, the most you can probably get is some kind of audible alert that something just hit a predefined limit. Low voltage or high temp, then it’s time to land etc. That doesn’t help you win the round, it just makes it more likely you can fly the next one.

By the rule book the DX8 would be clearly illegal for pattern because of the telemetry. I doubt anyone would declare it so however.

Jerry,
If you don't need more than 8 channels, I'd recommend the new DX-8 -- has telemetry back to the Tx for 4 data sources. I have one. The sticks re really silky and the 11 ms frame rate is VERY fast... $430.00 for Tx, Rx and telemetry module...

Jon, thanks for the input. I have decided to replace my old Stylus (1995 version) and have started checking around. Looks like 2.4 is the way to go.

Jerry,
I just had one and sold it. Reasons:
No stick switches
No split expo on each side of neutral. I use split expo, especially on elevator.
Mine came with the infamous stick deadband on three axes and I ended up sending it back twice to get it properly repaired.
Lockouts/glitching. Found a burned/corroded antenna connection in the receiver and sent it back for repair. Another Aurora 9 flyer also had glitching/lockouts at our field.
Only had digital throttle trim, and it cannot be mixed or assigned to a slider such that it only acts on low throttle.
They promise lots of feature updates via firmware, but are VERY slow in releasing anything. And they won't say exactly what will be in the next release. Bugs in heli and sailplane setups. Requires purchase of a separate box to update firmware. Website in Korea that has the updates has had frequent outages. You CANNOT download the firmware and install it later. You MUST be hooked to the internet and download it real time. My perception is that they are more enthralled with telemetry (that was a year late in being released) than in getting the basic system up to snuff. Oh, and as far as I know, they still haven't released the 72mHz module promised last fall, if that is of any concern.
Was glad to get rid of mine.

I seem to remember someone did a vey thorough review of this radio a short while back. Does anyone remember who, and what Magazine-when?
Thanks
Jerry
