KAVAN Smart PRO Opto ESCs - Instruction manual

Introduction

Smart Programmable Electronic Controllers for Brushless Motors

Congratulations on your purchase of a KAVAN Smart PRO line electronic speed controller for brushless motors. The KAVAN Smart PRO product line represents advanced brushless motor controllers for use exclusively in RC model aircraft. With integrated telemetry and various user configuration options, the controllers offer high efficiency, low weight and precise motor control. All the ESCs can be quickly programmed using your transmitter, PC or an external terminal.

Installation

Fix the controller in your model with the screws. Alternatively, you can use Velcro or double-sided tape to secure it. Connect the motor and receiver according to the diagram below. You can connect the motor cables in any order you like, as changing the direction of rotation is done by swapping either of the two cables (alternatively also by the "Direction" parameter in the configuration). Switch on the transmitter and then the receiver - the latter uses a separate battery. Now you can plug in the main flight battery.

Controller mode

It is possible to select from three basic controller modes:

• Normal - the preset acceleration curve is always used when accelerating. This is the default mode for normal use.
• Fast mode - the selected acceleration time is only applied when spinning from zero speed. Then the minimum possible delay (0.2s for zero to full throttle response) is applied.
• Normal with reversal - behaves similarly to normal mode. In addition, you can select a throttle reversal channel that will control the direction of the engine speed during flight.
• Heli/Governor - fast and precise constant speed control with many adjustable parameters.

Gas input signal

The controller expects positive pulses from the receiver with a maximum refresh rate of up to 400Hz. By default, when the endpoints are set automatically, the controller will work with the vast majority of RC systems. In this case, a minimum throttle signal pulse is loaded upon startup. The maximum output is then dynamically adjusted when you first give full throttle.

In case you need the exact positions of the transmitter lever, where the engine starts and where the throttle is full, you can configure using manually entered endpoints.

Engine settings

Many motor parameters can be configured including acceleration, timing, gear ratio or number of poles. The gear ratio and pole count are important for telemetry and correct display of motor speed.

Acceleration affects the engine's response to the throttle channel. Reducing the acceleration time will speed up the engine response and give the pilot a sense of instant control during aerobatics. However, the engine consumes more power and the controller generates more heat. For most types of models, including electric gliders, layouts, EDFs, etc., we recommend a default acceleration of 1.0s. For 3D aerobatic flight you can go down to 0.5s or even less (with caution). You can also set the controller's "Fast Mode" in the General Settings menu for the fastest possible motor response.
