Another excellent video and learning a lot. As soon as I start building count me in as a Patreon!

Here at our club we all paint with exterior latex. The UV protection is adequate and some of the planes have been painted many years ago but still look good and the fabric stands up..

One thing I learned from covering RC planes with monokote is to tack down the material in the middle of the rib on one end of the wing then on the opposite end of the the wing pull tight and tack in the middle then work opposite corners. The material on the leading and trailing edge should just fall out straight. After shrinking you will still get a little sag between ribs but it will be less. Love these videos.

Floetrol added to latex will help improve the finish and makes tipping more effective in removing bubbles and brush marks. It may be worth looking into for this application.

Hi Andrew - We tried Floetrol a number of times (differing strengths) and found NO benefit compared to water. In fact the label warns that it will also cut down the gloss. Also tried the 'windshield fluid' with no results (changed the paint color!) I suggest everyone experiment to find what they like best.

You can also add windshield wiper solution to thin the paint, it's a technique the RC folks have been using for years

Great to see you using alternative processes. The painting portion of the project is what I would be most worried about in this build. Love the idea of latex & brush & roller, I can do that.

Thank you for a most informative series so far. I am very keen to see how you cover around the strut attachments on the wing. I imagine you would have to over the under surface first, attach the strut fittings , and then cover the top surface. But I need to see how you did it. Thanks again for a very interesting series.

i covered 36 feet x 4 feet wing both sides top and bottom with 8 pounds of covering and my dope - sealer . Its for pick up and run or towing .

Hi again. The machine used by the paint shop is called a colour densitometer. It measures the density of the primary colours in the materials stuck into it and then feeds it to a omputer.

I’ve always wondering how the “sagging” between the ribs affects the lift or flight characteristics of the wing. It’s probably negligible but I wonder if adding a small strip of aluminum at the bend would straighten it out at all. Keep up the good work! I can’t wait to see her fly.

I would guess that with the direction the air is traveling, it's probably not much of an issue, other than being a slightly less-efficient airfoil shape in between the ribs. An ultra thin long and flat strip of sheet metal 2-3 inches wide molded over the top of the bend would be interesting...

I know close to 0 about aerodynamics, but I'd think that would create a ridge that would interrupt smooth airflow over the LE (and weight). As it is now it's like a blend between 2 airfoil shapes.

Hi Jon. I'm still waiting with baited breath to see how you covered around the strut attachment points on the wing. I've been trying to work out a method of doing this for some time. The only way I think I can get it to work would be to cover the under surface first, install the attachments , and then glue on a patch to reinforce the area. Do you agree so far? Once the upper surface of the wing is covered access to the attachments is no longer possible. I intend to use castellated nuts and split cotters for these attachments as inspecting them is impossible.

I think we have all been brain washed into useing the paint the big boys use. Latex paint should be just great. I used a latex paint on my first house I owned. It was still going strong 30 years later. Amazing. I'm all for useing latex paint.

I’m sure you’re aware but I’m still going to say it. Latex exterior house paint Is not approved for aircraft use. Yes, you can use it on an experimental/ ultralight home built aircraft no if ands or buts about it, totally legal. But also as you’re probably aware neither Stewart systems or poly fiber have tested latex paint. Now, they are made to conform to particular TSO’s for being able to obtain STC for multiple certificated aircraft. Now, if the system manufacturer has never tested their products with latex we have no idea how it’s going to perform. I guess this is how I look at it…what’s legal vs what’s safe. How will the chemicals used to manufacture latex paint interact with the polyester fabric? Will it degrade its strength? No one knows? I think it’s better to use the system according to the stc instructions whether it’s going on a certificated aircraft or not.

I'll sure PASS on the house paint thing..........IF House paint was the "IN" thing Airbus & Boeing would be hot on this🤔,.. I'd do a aviation paint demo with a layered sprayed on job vs. what your doing here........... do it on a 1ft. sq. of the wing covering let it flash out then compair. ... Just my take on this,🤨 I do think I can shoot a much lighter under coat / color coat combo.... latex is heavy.

You could say that about anything in the experimental world. Airbus and Boeing do the stuff they do because the aircraft they built operate in a regime that is orders of magnitude beyond the types of stresses that a Part 103 ultralight needs to be stressed to in order to be safe. Also, their customers have significantly deeper pockets than you or I do.

the airliner manufacturers use 2 pack hardening paint, that is as tough as concrete and operates in an infinitely tougher environment than any microlight. Jon's choice is good enough.

This is experimental aviation, and Part 103 has no certification requirements, so people are free to try out new ideas. Latex paint is durable, UV protection built in, and proven across many different experimental airplanes for many years. You are absolutely free to follow your heart and apply an expensive commercial paint process to make your plane last for 100 years, but for an ultralight that will likely have a much shorter life the latex approach is sensible and quite effective.

Just thought I would add a study that I did about 2 decades ago regarding latex paint and UV protection. The Affordaplane is looking good - can't wait for the taxi and flight tests. Ultraviolet Absorption of Latex Paints - drive.google.com/file/d/1Mk1CbjdCeKOIfFlf5kyZfDeSc7jO0aRd/view?usp=sharing
