I have had problems when running V2.00. I can't say that the failures I had are definitely caused by the hitec receiver. I had three failures on two…"

Janne Mäntyharju left a comment for Robert McC"Hi!
You asked about Aurora telemetry data format. You can find how the information is transmitted by looking at the sources of the device I made: https://gitorious.org/apm-hss-emulator/apm-hss-emulator
Basically the receiver sends a request via i2c…"

Marooned commented on Janne Mäntyharju's blog post Showing APM telemetry data on Hitec Aurora's screen"If you store the starting location you can use current GPS to display the distance from the aircraft and direction. Sounds highly useful."
Matthew Coleman commented on Janne Mäntyharju's blog post Showing APM telemetry data on Hitec Aurora’s screen (revisited)"Warning to all Hitec A9 radio users. There is a serious issue with older receiver firmware. The receiver has an intolerance to heavy interference resulting in long lockout periods (and crashed aircraft!). Make sure you do a…"

It can't beat Turnigy and others in price, but it's very cheap compared to Futaba and JR products. It feels very solid and quality product and has very good features in it's price class.
Now if…"

"I also run two 3s packs in parallel, but I didn't want to make the cables.
Got this instead. If you got a charger that can support it, you can charge 6 packs at once. It's only $9.

Simulated charging arrangement. Always use fireproof container for the batteries when charging!I updated my charged to balancing one a while ago, but for some reason I didn’t buy one of those new multichargers, which pack a number of separate chargers in to one device.

Using 3G modem, would provide almost unlimited range (I know there has been some discussions about this in DiyDrones forum. Here in Finland the GSM network is very covering, but due the way the cellular towers…
