Adhesives - You will need two types of adhesives for the
Rare Bear - Epoxy and Instant (cyanoacrylate) adhesives.
We recommend that you purchase both 5-minute and 30minute epoxy to cut down on assembly time,but you can
get by with only 30-minute epoxy if time is not important.
You will also need a small bottle of both “Thick” and “Thin”
instant CA adhesive.
Tools - Model assembly can be much easier if the proper
tools are used. Therefore,we have included in our checklist
to the left, a complete listing of all the tools we used to
assemble our prototype models. As you will notice, many
household tools can be utilized during construction.
Engine - The Thunder Tiger
PRO-60,PRO-90 are the ideal
engines for this airplane.These
quiet-running engines are easy
to start, require no special
break-in periods,are very easy
to maintain and will last for
years.
Muffler (P/N TTR9791) Most Pitts style mufflers will
fit this Rare Bear. However,
we recommend the use of
Thunder Tiger custom-made
Rare Bear muffler with two
exhaust pipes that divert the
smoke into the two
concavities of the fuselage to obtain a more scale-like
apperance . This muffler fits TT and OS .60~.90 engines.
