"That is one cool design Tridge, Seems like you could almost get by with free pivoting prop motor units, maybe spring loaded a bit or with appropriate weight / pivot offset. I can't tell if that one is using a servo or not. Best Regards, Gary"

Banggood is now taking pre-orders for a VTOL wing. It seems to be the holy grail of VTOL to me - no redundant motors, no extra servos, so it's a simple, reliable, and above all, efficient.…

A Practical APM Mobile Ground Control Station

Posted on April 18, 2016 at 6:55am 4 Comments

In the last 4 years of being involved with UAVs I’ve always lacked a good ground station, one that’s practical and quick to deploy.

 

So I started drawing up a list of requirements. I had to draw the line somewhere, or the cost and weight would run away, so I ended up with a shortlist of…

The Perfect UAV Mapping Camera

Posted on April 18, 2016 at 12:56am 17 Comments

It’s really strange that there’s been so much development in all other aspects of UAV Mapping, except one – the camera!

FPV Flight to Robben Island

Posted on December 5, 2013 at 7:30am 22 Comments

A quick documentary of my FPV flight to Robben Island, where Mr Nelson Mandela was imprisoned for 18 years.

 

Back then I was very worried about flying over water...

 

This was before Cruize mode :)

 

About 16km and 35 minutes, safe touch down!
