EVP 4D Electric Variable Pitch

First we want to thank you for choosing our 4D Electric Variable Pitch，and we

believe it will bring you a completely different feeling.

Before using，we suggest you keep distance from this equipment，cause it has a

total different operating way form traditional styles.

1. Preparation：

1.1 First you should make sure your motor is hollow shaft motor.

1.2 Then you should prepare a micro servo to drive the steel wire on our EVP system.

1.3 TX&RX：≥ 6channels.

1.4 It will be much easier for you if you do screw pitch setting under some experienced

helicopter hobbyist.

1.5 Please use suitable ESC and battery according to our testing records.

1.6 Last，a strong enough frame is needed in case of damage cause by fast variable

pitch.

2. Installation：

We suggest you use our finished combo directly，which will help you get into the flight

envelope easier.

2.1 Replacement of motor’s hollow shaft：

2.1.1 Take down the clip and screw used on the motor.

2.1.2 Strike the motor shaft down softly. We suggest you use some tool to reduce the

damage of the motor when take off the shaft.

DMode （Idle UP Mode） 5. Suggestion Before using，we have several suggestions as follows： 5.1 Fly on a soft grassland for your first trial flight.

5.2 Prepare for two modes，Normal Mode and 3D Mode，in case of need. 5.3 Make sure that your equipment has enough thrust under 3D Mode. Take above picture of 3D Mode as an example，although the motor is under 40% throttle，thread pitch is 0. No Thrust at that time. 5.4 The load of electronic equipment will extend suddenly the moment position thread pitch turns into negative thread pitch. Please pay attention. 5.
