Introduction
Thank you for purchasing AMR product. AMR (Aircraft Modelers Research) prides itself on bringing you the finest aircraft model kits
due to our team efforts and our state of-the-art equipment that affords exceptional quality. Using CNC driven production equipment,
each of our kits is individually laser-cut according to plans which includes custom fittings and hardware sets specific to your model.
We, as the kit manufacturer, provide you with a top quality kit and instructions. However, the quality and flying ability of your finished
model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model and no
representations are expressed or implied as to the performance or safety of your completed model.
Before starting to build, use the Part List on the next pages to take an inventory of your kit to make sure it is complete and inspect the
parts to make sure they are of acceptable quality. Remember to take your time and follow the instructions to end up with a well-built
model that is straight and true. If any parts are missing, not of acceptable quality or if you need assistance with assembly, contact AMR
Customer Service. When reporting defective, missing parts or replacement parts, use the part number exactly as they are written.
Enjoy!

Before you begin, important notes from A.M.R
1-) This model airplane is not a toy. It must be built with outmost care. It is imperative that you follow each steps of
the building manual. If you need assistance of any kind, please contact us directly.
2-) Adhesives:
a-) For general assembly, carpenter glue works best and provides a very strong bond.
b-) C.A adhesives can be used. However, their high-toxic level makes them uncomfortable for some builders. It can be
used to tack parts or on non-structural parts.
c-) IMPORTANT: For hi-strength sections, you must use “Structural Epoxy”types, not the 5 or 30-minute types
available in most hobby shops. In this manual, you will notice that some assemblies do mention “use epoxy”and
you must do so. Structural epoxies penetrate deep into the wood fibbers, creating a very strong bond. We
recommend these brands: G2 Epoxy kit, T88 Epoxy or West Systems. They are available from any Aircraft or
Marine specialty shops in convenient sizes. Carefully follow their mixing ratios.
3-) We recommend that all control horns be 10-32 types (no less) and that all screws/nuts be secured with thread
locker.
4-) A straight airframe is the only way to go. Make sure that you have a straight building surface before you begin
building.
5-) Sanding bars: Using ½”balsa planking (not included) make 3 of them, 3”wide x 18”long with some 100, 180 and
280 grit sand paper.
6-) If something looks wrong, it probably is. Make sure that you follow the building sequences with the appropriate
part number.
7-) Take your time and verify the alignment before final gluing. This extra caution will eliminate possible frustrations.
