Top Flite TOPA0305 Part 1 - Manual (Page 5)

PRECAUTIONS
You must build the plane according to the
plans and instructions. Do not alter or modify the
model, as doing so may result in an unsafe or
unflyable model. In a few cases the plans and
instructions may differ slightly from the
photos. In those instances you should assume
the plans and written instructions are correct.
2. You must take time to build straight, true
and strong.
3. You must use a proper RIC radio that is in first
class condition, the correct sized engine and
correct components (fuel tank, wheels, etc.)
throughout your building process.
4. You must properly install all R/C and other
components so that the model operates properly
on the ground and in the air.
5. You must test the operation of the model before
every flight to insure that all equipment i s
operating, and you must make certain that the
model has remained structurally sound. Be sure to
check external nylon clevises often and replace
them if they show signs of wear.
6. If you are not already an experienced R/C pilot
you must fly the model only with the help of a
competent, experienced R/C pilot.
NOTE: We, as the kit manufacturer, can provide
you with a top quality kit and great instructions,
but ultimately the quality and flyability 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 t o t h e performance or safety
of your
completed model.
Remember: Take your time and follow
directions to end up with a well-built model that
is straight and true.
DECISIONS YOU MUST MAKE
TAIL CONFIGURATION
You may build your Bonanza as a straight tail
or a V-tail. Complete instructions are provided for
both. The main differences in construction are
building the tail surfaces themselves, the way
they mount to the fuse, and the turtle deck
sheeting. If you wish to utilize the elevators as
ruddewators (elevators and rudder) on the V-tail,
you will need a computer radio with V-tail mixing
or a servo mixer such as the Ace MixMaster
(ACEM2510). However, the Bonanza will fly just
fine with elevators only and no rudder input. Do
not be intimidated by the V-Tail configuration. It
flies beautifully and is as easy to handle as the
straight tail.
ENGINE SELECTION
Recommended engine size:
.60 to .91 cu. in. 2-stroke -or- .90 to ,120 cu. in. 4-stroke
The Bonanza will fly well with any of the
recommended engines. The 4-stroke engines
and most .75 2-stroke engines will turn a larger
prop at lower RPM’s. This is often desirable for
scale realism. Many .60 2-stroke engines
produce about as much horsepower as the
popular
.75 or .90 2-stroke engines and will fly
the Bonanza well. If you use a .60 2-stroke, a
ball bearing, Schnuerle-ported engine is highly
recommended. Our prototype Bonanza weighed
13 pounds with all of the options, including flaps,
scale cockpit interior and operational lighting,
and was flown with a SuperTigre
G-75. It turned
a Top Flite Power Point 12x8 prop at 9,600 RPM.
This engine provided excellent performance
and more than enough power, even in gusty
winds.
Although larger engines can be used to
power this model, the extra horsepower is
not needed.
The included adjustable engine mount will
hold a range of engines from .60 2-stroke
through 1.20 4-stroke.
EXHAUST SYSTEM
A Top Flite header and muffler are available
that will fit inside your cowl. They are designed
for 2-stroke engines mounted horizontally, as
used on the model and shown in the instructions.
For part numbers see the accessory list on page 6.
RETRACTABLE LANDING GEAR
You may build the Bonanza either with fixed or
retractable landing gear. Of course, fixed gear
will be much easier to install than retracts; but we
provide detailed instructions on retract
installation
so you should have no trouble. We
chose the Robart #BZA80 retracts because they
are specially designed for this model. This
landing gear is a special adaptation of the Robart
#640 mains and the #631 nose gear. Other
systems may work as well but it is up to you to
make modifications to fit them into the model.
This model was designed to incorporate scale
flaps; however,flaps are optional are not
necessary for an excellent flying experience.
Without flaps, the takeoff roll is longer and the
landing speed is faster.
The flaps are not difficult to build, but they do
require good craftsmanship to fit well. Flaps add
nicely to the model’s flight characteristics and
scale appearance while causing no bad effects.
Only slight trim correction is needed when they
are used with the recommended throws. They
are a highly recommended
fun option for those
who wish to install them. More information on
the use of the flaps may be found in the
“Flying” section.
