I wish there was more in that story about the nuts and bolts of the flight system. It looks very well designed and thought out. I'd say that plane probably has a far superior range of a multi rotor but it's interesting ,and perhaps telling, they didn't share any footage of how they retrieve the plane. That is one advantage of a multi rotor you need basically zero ground clearance for take of and retrieval. Like anything I guess it's hard to have your cake and eat it too.

That's weird timing....a nearby college is sending a few people to Rwanda next week with a multirotor to do some mapping.

I've been building an IconA5 Seaplane as I want to test AUTO takeoff and landings on water with ArduPilot. I managed to crowbar a pixhawk and accessories into the plane - just.
The plane comes with removable wheels so I thought I'd fly and tune it on land first. The problem I was having was the nose wheel. It is VERY fragile and I broke it almost immediately. I spent some time trying different ways to secure it but still have it removable for the water takeoff/landings. After it came off again Tridge dared me to try an AUTO takeoff without wheels - CHALLENGE ACCEPTED!!!
It worked!  Video here:
This is actually the second AUTO takeoff with no wheels. Because we didn't think it would work we didn't film the first.
This is a full ArduPilot AUTO takeoff. I simply flick the transmitter switch to put the plane into AUTO mode and it does the rest. This is why it heads to the right a bit. Normally in AUTO takeoff the plane will auto takeoff in the direction its pointed i.e. straight down the runway however as it has little directional control on the ground and "squirms" a bit until it picks up speed its direction isn't perfect.

Do you guys have links on how to install Airspeed sensor on MINI APM 3.1?

@ Grant when was the large update done?

I've been flying the dev version since about 3 weeks ago. I was very keen on the 'boat mode' aspect. Works great! 20-30 flights.

I might have notice it resetting it's home position whilst in flight with 13 sats which was odd. This was reported to me by my GCS...  but not sure really what happened might have been my GCS / tower lost connection I'm really not sure. My guess is it was me. I had 13 sats when it happened but I might have armed with only 6-7 so ... it was probably me. But if you hear of others.....

 BTW... do these numbers give you details about the date / build version? 

PX4v2 0036002D 30345101 37383933

Anyway it just keeps getting better :] Thank you!!!!!!!!!!!!!!!

If any keen users out there are being super brave and running the autopilot with the master code base and have odd behaviour they haven't previously noticed we would love to hear from you.  A large updated has been done to the PX4Firmware code and we are keeping out an eagle eye for any odd behaviour.

Thanks, Grant.
