Molt Models Background Design Philosophy
When I was first introduced to this hobby in 1985, the first plane my Dad and I flew was one of
the typical .40 sized glow powered trainers still available today. Since then however,
technological advances in both electric motors and batteries have completely changed
the look of radio controlled model airplanes. These changes also brought forth a completely
different style of trainer airplane. Many of these new electric powered trainers are
wonderfully stable and easy to fly. However, in my opinion, they lack flight characteristics
that I associate with the typical .40 sized glow powered trainer that truly prepare the novice
pilot for the next level of flying. The Molt Models Tyro150 contains all the capabilities
associated with the typical .40 sized glow powered trainer, but includes the simplicity of
electric flight and a much lower wing loading.
The Molt Models design philosophy is comprised of methods that enhance appearance and
all around flight performance. The first thing you’ll notice about a Molt Models kit is that the
majority of wood parts, illustrations and plans are CAD based. These items are derived from
the same 3D modeling environment that the plane was designed in. My goal is to cut down
on wordy instructions and use a more visual approach that will get you from kit to airborne in
as little time as possible.

Thank you for purchasing the Molt Models Tyro150. This kit represents a true first in 4-channel
electric trainers in that it possesses characteristics that make it both enjoyable to build and
more importantly, fly. I sincerely hope that you enjoy your new Molt Models kit. Please visit

General model building tips, orientation, and how to use this manual
First and foremost, this kit is for the first time wood kit builder. However, it is still important that
you study this manual and get help from an experienced builder if you run into trouble.
Please be sure to read through the following instructions before attempting to build your
Tyro150. Having a good idea of what to expect as you progress will cut down on mistakes
and allow you to better organize your project. Checkboxes have been provided in front of
each step, allowing you to easily keep track of your work.
Thin CA glue is suitable for almost all the build sections of this model. If another type of glue
is necessary for a certain build section it will be recommended in that segment.
Standing behind the plane orients the left and right side of the model. These building
instructions refer to areas of the model in this manner. All dimensions are presented in English
units.
Each section of this manual is organized by showing portions of the plane being built from
general construction all the way to covering. However, most experienced builders prefer to
completely build each component to the point where it is ready to be covered, build the
next components, and then cover all the components at the end of the building process.
Feel free to use the checkboxes to help keep track of where you are in the building process
regardless of which method you choose to follow.
