<span style="font-size: large;">Nitroplanes Skymaster 337, 81” Build Tips</span></div>
I’m starting this thread to show you how I overcame some of the problems with this build and to explain a few modifications that will make field assembly and operation of this plane easier and more enjoyable.<div style="text-align: center;">
<span style="font-size: medium;"><u>Strength</u></span>
</div>Before assembly began, I went over the whole fuselage with epoxy and CA to make sure all joints were secure. Added some where I felt it needed it. CAUTION: make sure you do NOT let glue get into the landing gear mount assembly. This is a tight fit and some day you might want to remove the main gear for replacement. I also applied a thin coat of 30 min. epoxy over the entire inside the front and rear cowlings. This is something I do with all my planes. It adds substantial strength to the cowl and keeps it very clean inside. When these engines spit and sputter fuel it always soaks into the fiberglass. A real pain to clean! With the epoxy coating most fuel just runs off. And wiping out the cowl is a breeze.
I also put larger wheels on this plane. The kit comes with 2 1/2” foam wheels. I went with Du-Bro 3” rubber wheels for a better look and smoother landings. Believe me! I can use all the help I can get!
When installing the side windows, don’t separate the front pair. They fit right in while still connected. Just trim away some of the edge molding. When trimming the covering away from the window openings, leave enough extra covering to wrap around the wood and attach to the inside of the fuselage. I used a white paint marker to cover bare wood in the window corners. I also kept every scrap of covering that I cut from this plane to use as patches.
I would like to know what brand of covering is used on this plane. Does anyone know?
