One of the first steps is to tighten the covering. It is self adhesive and stuck to the wood. It is, by no means taught and will quickly sag when it gets its first exposure to the sun.
I can't vouch for the covering other Nexa birds other than my wife's Ju-52 and the F-82. The covering will shrink up and adhere to the wood better with the use of a covering iron and some patience.
Testing shows that a temp of 175 - 185 deg F seems to work well. Its best to have a sock on the iron to protect the covering.
Work the iron over the airframe slowly. In open areas, you'll see the covering sag more before it starts to shrink up. It areas that can't vent the hot air, like the lightening holes it the control surfaces. It's best to make a small puncture where the pocket is, with a hobby knife on the underside. That lets the hot air out so the covering can shrink.
It would be nice if the builders at the Nexa factory could do a littler job of prepping the airframe for covering. Some areas look like they were sanded with a bench grinder. lots of rough grain, filler and sanding debris trapped under the covering. I know that these are "budget" airframes, but a little extra prep could go a long way toward a better looking product.
