Building a UAV for photo mapping - Trial Balance





I have now finished all the sub-assemblies of my Cularis, so before sticking the fuselage together, I decided to do a trial balance to check on the COG. Here it is, poised on the wing

Building a UAV for photo mapping - Kit Mods



First I must thank Jeffrey Johnson who posted a set of images of the Cularis he is building for photo mapping. He has made a really neat modification by moving the rudder and elevator servos from the stock

Building a UAV for photo mapping - The Goal

Hi
