These are general guidelines measured from our own flight
tests. You can experiment with higher rates to match your
preferred style of flying.
Travel Adjust, Sub-Trim and Dual Rates are not listed and
should be adjusted according to each individual model and
preference.
Note
: We highly recommend re-binding the radio system
once all the control throws are set. This will keep the servos
from moving to their endpoints until the transmitter and
receiver connect.
Preflight
For those of you who are veterans of large models, this
is old news; but to you newcomers to the world of large
models, this is very important information:
While many smaller models are not critical of proper battery
use, and are tolerant of improper control linkage setups and
flying techniques, large models are not. Don’t let that scare
you away from large models, however, they are truly one of
the best flying experiences in RC that money can buy. Please
pay particular attention to the following areas—
Maintain the proper mechanical advantage on all control
surface linkages.
Just as with unsealed hinge gaps, mechanical advantage is
often another cause of flutter. Please follow the control horn
and servo arm lengths recommended in this manual. Shorter
arms on the servo or longer control horns on the elevator
and ailerons are fine, but do not try to go the other way to
increase throw. It can cause flutter or servo failure on the
Pawnee. The recommended linkage setups are more than
adequate to achieve full 3D throws.
Check the radio installation and make sure all the control
surfaces are moving correctly (i.e. the correct direction and
with the recommended throws). Test run the engine and
make sure it transitions smoothly from idle to full throttle
and back. Also ensure the engine is tuned according to the
manufacturer’s instructions, and it will run consistently at full
throttle when adjusted.
Check all the control horns, servo horns and clevises to
make sure they are secure and in good condition. Replace
any items that would be considered questionable. Failure of
any of these components in flight could mean the loss of
your aircraft.
Never attempt to make full-throttle dives!
Large models perform much more like full-size aircraft than
small models. If the airframe goes too fast, such as in a
high-throttle dive, it may fail.
Hardware checks
Double-check the setscrews in all control horns to be sure
they are very tight. Periodically check these to be sure they
have not loosened over time. Always use threadlock on
metal-to-metal fasteners.
Receiver battery selection
Be sure adequate batteries are used to power the receiver.
We recommended a minimum of 2700mAh capacity.
Range check
Always range check the radio system per the manufacturer’s
instructions before the initial test flight, as well as at
periodically scheduled intervals.
Check the voltage of the on-board packs
ALWAYS use an expanded scale voltmeter with a 1-amp
load to check the receiver battery packs and the ignition
pack before each and every flight. If there is any doubt that
the packs are questionable, DO NOT FLY until the packs are
recharged.
Range Test Your Radio
Before each flying session, and especially with a new model,
it is important to perform a range check. It is helpful to have
another person available to assist during the range check. If
you are using a Spektrum transmitter, please refer to your
transmitter’s manual for detailed instructions on the range
check process.
