Couple more progress pictures and a couple possible paint schemes. These were also found in the FlyHelio site gallery they kind of confuse me it looks like the original photo in 2011 or what I thought was the original paint scheme with the 12'' N4142D registry numbers.

I like the individual Electronics International gauges but prefer the combination instruments like oil temp/press.

Of the two paint schemes I like this one. Somewhat like the original

This paint scheme sems to be a takeoff from the factory 7/800 paint sceme

Those line drawings are not applicable to a true form, note that the stabilator location is too low and the wing is not at 3 degrees angle of incidence. However, they are meant for paint scheme renderings, so I get that part, but it would be nice if they actually rendered a correct profile of the Helio of any that I've seen.

Who cares this is just a paint scheme drawing the only requirement is to remember what they taught you in kindergarten you keep the colors from the crayons within the lines.

When you tape for outline things always seem to change from 2D PERSPECTIVE TO 3D.
