Profile Information

About Me:
I have recently re-ignited my interest in R/C airborne craft.
I think it was the FPV & AP systems that hooked me.
II work in special effects for film & T.V.
I'm no longer a kid but I still enjoy R/C boats and planes, model rockets.
I also like photography, boating (being around water), motorcycles & electronics.
Please tell us a bit about your UAV interest
I am interested in doing aerial photography.
It is my hope be able to map with photos, [for example; The area around a lake], from different directions to produce a "street-view" 360 Deg PAN -TILT etc. Maybe use it to show seasonal changes over an area.

There also are some new network node functions.

There are 3 more diagnostic commands and there are functions for I/O sampling.

I haven't read though the updated manual, yet, but I hope to get to this weekend if the weather… Continue
