Radio telemetry ordered

A few days ago, I decided that it was time to order a radio telemetry set. I went for the set from GoodLuckBuy.com (got to love that name) for roughly $36. However, today when I investigated into why I hadn't received any package tracking information, I discovered that the package hadn't event been shipped out. Slightly disappointing as the page does not clam that the items are out of stock. The support chat however informed me that the items were in fact out of stock. Big minus for that site.

Anyhow. Not loosing fate, I decided to order yet another item, which I found in the new arrivals at DealExtreme as well but for a higher price. This is a current and voltage sensor that is way cheaper than shiny once at Sparkfun.com. It looks the same and has the same specifications but for a lower price, $14. It's used to report how much juice is left in the battery back to the MultiWii flight controller, which may take action if the capacity is going low. Actions such as RTL or land. We'll see how this goes but the support attendee informed me that the item was in fact in stock. At least one item was..

Six weeks later

 

Six weeks ago, I ordered these items from Deal Extreme. Two weeks ago, I reported the package as lost and wanted an investigation into the possibility to get another package sent. However, the support department asked me to wait another week and here it is, the post office has done it's magic. Just wondering why some packages from China / Hong Kong arrive after nine days and some after six weeks. 

Anyway, to the right, a bluetooth to attach to the flight controller, which enables configuration and remote command both from a computer or smartphone. The Android app SteadiDrone enables remote control and the regular APM Mission Planner also allows for connection over bluetooth. The other thing is a USBISP thing that soldered to the Turnigy transmitter allows for firmware update. More on that in another post.
