Please tell us a bit about your UAV interest

Along with a group of RC interested engineering students and some wilderness search and rescue technology specialists we aim to develop and test affordable UAV systems to support SAR in the barren landscape and harsh environment of Iceland I am one of two "Angel-investors" supporting the project until we can apply for and hopefully get development grants. Two project ideas prevail at the moment: 1. a loitering drone (Arducopter?)for eye-in-the-sky, real time hi-res video downlink to the command center in search operations. 2. a winged autonomous drone for hi-res aero-photography, hopefully with a real time downlink for analysis using the crowd-sourcing principle.

"I got hold of some 433 modules now and look forward to testing them.
Having a (recently acquired) ham-license allowing me to transmit in the 430MHz band at power levels enough to cook chicken (500watts), I see no problem in using them other than the…"

"Quote from JVC :
Digital image stabilization minimizes camera shake, and the camera includes rolling shutter cancellation that corrects the image skewing that can occur with CMOS image sensors. The result is distortion-free images, even during…"

Before rebuilding a crashed Scarab Stealth-Reconn from Multiwiicopter.com (http://www.multiwiicopter.com/products/stealth-quad-fpv-reconn) and fitting it with my new APM2 board instead of the Paris board I would like to hear if anyone already has…

"Not sure what plane you are referring to. Do you have a picture?
From the information you give it seems that the thrust line of your motor is wrong. You may have to adjust it depending on how it is configured. If it is a puller (in the nose), it may…"

"Hi Jerome
Your English is absolutely "pas mal" :) 
As a recent starter myself and still a newbie and judging from my own experience I would say this:
Go with the Jdrones quad as a first multicopter. It is well proven, gives you all the starting…"

"I forgot to add that the experts said the scanner would not work because of the air in the ice. Ævar and Marteinn did not know that and made the thing and it worked."

Björn Geir Leifsson commented on Chris Anderson's blog post Balloon-launched and disposable UAVs
"Interesting discussion. 
Many inventions have been made by men who did not know that the academics had calculated that it could not be done. 
An example is the ice-scanner that found The Lost Squadron in the Greenland glacier. It was first made by a…"
