Jason Ferrier replied to Björn Geir Leifsson's discussion Multiwii Scarab with APM?"I am considering purchasing a Scarab QUAD X Stealth without a control board and using an APM.
Are there any issues I should consider before doing this?"

Björn Geir Leifsson commented on Matthew Schroyer's blog post Dangerous situation - RC catches fire while testing APM 2.0. Suggestions?"Oh,, and if the extinguisher dust is pale yellowish it is probably ammonium phosphate, which is corrosive. Also the white powders used in extinguishers (Sodium or potassium carbonate) are rather corrosive and may easily ruin your equipment.…"
Björn Geir Leifsson commented on Matthew Schroyer's blog post Dangerous situation - RC catches fire while testing APM 2.0. Suggestions?"There's a sizeable electrolytic capacitor in ESC's. It looks like a small drum, usually sitting between the feeding wires. From the pictures it looks like this capacitor burnt up and torched the hole in the fuselage…"
Simon replied to Björn Geir Leifsson's discussion 3DR Hexacopter setup, some questions"Hi Bjorn.
I have a jDrones kit and I have had a couple of crashes with these props and they have held up quite well

At least they seem to be much stronger than the…"
DistributorMartint BuildYourOwnDrone.co.uk replied to Björn Geir Leifsson's discussion 3DR Hexacopter setup, some questions
"1) Yes and no, there will be less resistance to turning the blade, so yes there will be a better spin up spin down as the energy in the blades is not so high, I have a number of customers running on the 880 and 10" props, so far they are going…"
Björn Geir Leifsson replied to Björn Geir Leifsson's discussion 3DR Hexacopter setup, some questions"Thanks Martin
1) I also suspect the 880 - 10" might come out nice since shorter props allow for faster transitions and smaller ambient wind resistance. Maybe the difference is minimal but... I'll try that first. 880 can carry larger…"
DistributorMartint BuildYourOwnDrone.co.uk replied to Björn Geir Leifsson's discussion 3DR Hexacopter setup, some questions
"Hello Bjorn,
1) 880Kv with the 10" props allows you a better flight, plus you can add the extra inch or two prop later on should the need come about to lift more weight.
2) Optical flow sensor is on for the APM 1 & 2, in the Wiki…"
Björn Geir Leifsson replied to Andrew Tridgell's discussion Regulatory compliance for the 3DR Radios"Good. Let´s not drift off the thread topic of regulatory matters. When we´ve collected more info on performance we´ll carry on in a new or more appropriate thread."
Björn Geir Leifsson replied to Andrew Tridgell's discussion Regulatory compliance for the 3DR Radios"@Martin Perhaps contacting the module/chip producers directly and ask if their product has the necessary approval?"
Björn Geir Leifsson replied to Andrew Tridgell's discussion Regulatory compliance for the 3DR Radios"The "simple answer" is that the range will be totally dependent on your antenna (and its feeding line if one is used) at both the drone and the ground station. Getting as close to the optimal setup in that respect is the trick if you want…"
Björn Geir Leifsson replied to Andrew Tridgell's discussion Regulatory compliance for the 3DR Radios"Well Martin, it is really a hit and miss with the customs officers. Iceland is not EU but has applied all the red tape through bilateral agreements along with Norway and some other small states. The CE mark is a holy insignia here too. THe worst…"
Björn Geir Leifsson replied to Andrew Tridgell's discussion Regulatory compliance for the 3DR Radios"I got hold of some 433 modules now and look forward to testing them.

- 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´d like to share this video with you all. partly to brag about how good I am getting at flying the quad and partly to show how it behaves in a stiff(-ish) and rather turbulent wind. More info in the text on youtube

(Apologies for the camera tilt) In this clip I am on the second 3000mAh battery and tentatively testing the altitude hold.…
