I would imagine many of you have seen this done in the past on other Hexa,s. I had to do this to my S800 EVO due to the fact that at distance looking at the craft whose background was the treeline,I would loose visual orientation of the black hexa. Any good hobby shop will have what I used here in the attached photo. The vinyl material which has a self adhesive backing came in a 6 inch by 3 foot strip. I cut it to size on the matte cutter I use for my photographs. Cost of the materials was $5.00 from Hobby Town. On the back 2 booms on the H is where I located both my FAA and Tele #.
