Recommended Control Throws:

The amount of control throw should be adjusted as closely as 

possible using mechanical means, rather than making large 

changes electronically at the radio.

By moving the position of the clevis at the control horn toward 

the outermost hole, you will decrease the amount of control throw 

of the control surface. Moving it toward the control surface will 

increase the amount of throw. Moving the pushrod wire at the 

servo arm will have the opposite effect: Moving it closer to center 

will decrease throw, and away from center will increase throw. 

Work with a combination of the two to achieve the closest or exact 

control throws listed.

Aileron 1/2” up/down 

Elevator 1/2” up/down

Rudder 3/4” left/right

These control throw are suggested and work well. We ask that 

you start with these settings, then adjust them as needed as you 

become familiar with the flying characteristics of your Mambo.

Preflight:

Charge both the transmitter and receiver pack for your airplane. 

Use the recommended charger supplied with your particular radio 

system, following the instructions provided with the radio. In most 

cases, the radio should be charged the night before going out 

flying.

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.

Range check your radio before flying

Before each flying session, range check your radio. This is 

accomplished by turning on your transmitter with the antenna 

collapsed. Turn on the radio in your airplane, but do not attach the 

arming switch.

With your airplane on the ground, you should be able to walk 30 

paces away from your airplane and still have complete control of 

all functions.

If not, don’t attempt to fly! Have your radio equipment checked 

out by the manufacturer.
