WARNING! WARNING: Read the ENTIRE instruction manual to become familiar with the features of the product before operating. Failure to operate the product correctly can result in damage to the product, personal property and cause serious injury. This is a sophisticated hobby product and NOT a toy. It must be operated with caution and common sense and requires some basic mechanical ability.

Kit inspection Charging the Flight Battery The Battery Charger is designed to safely charge the Li-Po battery, Caution: All instructions and warnings must be followed exactly. Mishandling of Li-Po batteries can result in fire, personal injury, or property damage. Battery warning: By handling, charging or using the included Li-Po battery you assume all risks associated with lithium batteries.
Low voltage cut off (LVC) When a Li-Po is discharged below 3V per cell, it will not hold a charge. The ESC protects the flight battery from over-discharge using Low Voltage Cutoff. Before the battery charge decreases too much, LVC removes power from motor in two ways: (1) Reduces power ESC reduces motor power (recommended), (2) Hard cutoff - ESC instantly cuts motor power when the pre-set Low Voltage Protection Threshold value is reached. These settings can be changed using the ESC programing guide.
Get your model ready to fly Important ESC and model information 1. The ESC included with the Sbach 342 has a safe start. If the motor battery is connected to the ESC and the throttle stick is not in the low throttle or off position, the motor will not start until the throttle stick is moved to the low throttle or off position. Once the throttle stick is moved to the low throttle o r off position, the motor will emit a series of beeps.
Get your model ready to fly The transmitter and model setup Before getting started, bind your receiver with your transmitter. Please refer to your Transmitter Manual for proper operation. CAUTION : To prevent personal injury, DO NOT install the propeller assembly onto the motor shaft while testing the control surfaces . DO NOT arm the ESC and do not turn on the transmitter until the Transmitter Manual instructs you to do so.
Get your model ready to fly 2. Adjust the servo arms mechanically make sure all servo arms are fully vertical. If not, adjust the servo arm by using the trim function on your radio. Note: For computerized transmitters, use the servo/channel sub-trim feature to make each servo arm fully vertical. Make sure the trims and the sub trims in neutral position before making some mechanically trim. 3. The standard hole settings for linkage connections are shown by the black arrows in the the diagram below.
Get your model ready to fly Check the control throws 1. Adjust ATV/travel adjustment on your transmitter until you obtain the following control surface travel. Do not adjust dual rates until you have correctly adjusted the total travel. Ailerons: 60 to 70mm up and down (both ailerons), measured at the aileron root. Elevator: 48 to 50mm up and down, measured at the counterbalance leading edge. Rudder: 60 to 65mm left and right, measured at the counterbalance leading edge. 2.
Before the model flying Find a suitable flying site Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will be required and have mastered flying your plane in confined spaces, choose a site which is at least the size of two to three football fields – a flying field specifically for R/C planes is best. Never fly near people– especially children who can wander unpredictably.
Flying course Take off While applying power slowly steer to keep the model straight, the model should accelerate quickly. As the model gains flight speed, you will want to climb at a steady and even rate. The Sbach 342 model will climb out at a nice angle of attack (AOA). Flying Always choose a wide-open space for flying your plane. It is ideal for you to fly at a sanctioned flying field. If you are not flying at an approved site, always avoid flying near houses, trees, wires and buildings.
Troubleshooting Problem Possible Cause Aircraft will not respond to the throttle but responds to other controls. - ESC is not armed. - Throttle channel is reversed. Extra propeller noise or extra Vibration. - Damaged spinner, propeller, - Replace damaged parts. motor, or motor mount. - Tighten parts for propeller - Loose propeller and spinner adapter, propeller and spinner. parts. - Propellor installed backwards. Reduced flight time or - Flight battery charge is low. aircraft underpowered.
