These are general guidelines measured from our own flight

tests. You can experiment with higher rates to match your

preferred style of flying.

Note: 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.

Preight

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; they are truly one of the

best flying experiences in RC that money can buy. However,

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

Sukhoi. 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 and

constantly 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 would 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. The Sukhoi should be flown

like a full-scale Sukhoi. Throttle management is absolutely

necessary.

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.

It is STRONGLY recommended that two identical 6-volt

receiver packs are used. Each pack must have a minimum of

2700mAh capacity. Use packs of 3000mAh when super high-

torque servos are used.

Range check

Always range check the radio system per the manufacturer’s

instructions before the initial test flight

and periodically afterward.

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.
