Hangpoint System
E-PAC features both high and low hangpoint options. Delivered in either format, E-PAC can be easily converted at a later date by the user with ‘optional’ arms and harness.

Frame
E-PAC’s, lightweight, profiled aluminium frame has been purpose designed for ease of assembly and transportation.

Consisting of 4 main cage sections which plug together around the body unit. Press clips and plastic looking straps join the sections to make a rigid protective structure. Frame sections are replaceable in case of damage.

‘Power Drive 160’ Motor
Yuneec’s ‘Power Drive 160’ out-runner brushless motor is sensor controlled for optimum performance and reliability. Smooth running, precise speed control, instant response and zero vibration make it the most user friendly power source available. Internal sensors also monitor key areas such as temperature and rpm.

‘Power Block’ Speed Controller
One of the most difficult parts to design of any electric drive system is the speed controller with reliability being the key issue. Yuneec’s ‘Power Block’ controller has been matched with the ‘Power Drive’ motor to give maximum performance and efficiency with total reliability. Internal temperature feedback with software protection, in case of overheating, enhances reliability.

The power block has been flown in testing for the last 9 months without a single failure proving that this controller meets all the demands made of it.

Charger
Charging is the most critical time for any battery pack and Yuneec’s engineers have designed the E-PAC charger with safety as the main priority.

The E-PAC charger monitors all 54 cells in the battery pack at the same time balancing them within .03mv. This charger was specially designed at Yuneec and is the only charger of its type in the world at present. No other commercially available charger can do this and it represents a huge breakthrough for electric power systems.

It is this charger that makes E-PAC battery charging so safe and in turn ensures that each pack is at its maximum capacity for use. It also maintains the batteries in a better state and so ensures the life cycle of the batteries is maximised.

Battery Pack
‘Plug and Play’ battery pack make E-PAC simple and easy to use.

Aluminium cased for cooling and damage protection, the E-PAC Lithium Polymer pack has internal ‘safety’ protection.

A special electronic circuit board measures the maximum output and maximum temperature and shuts down the pack should either maximum be reached.

The 30Ah pack has 54 individual 10Ah cells which are assembled to give 66.6V.

E-PAC can be fitted with an additional pack to give 60Ah capacity.

Hand Controller
E-PAC’s lightweight, easy to hold hand controller uses an RS232 data cable connection to the motor unit. This feature packed controller is left or right handed and gives a smooth and positive, throttle response, ideal for training and precision flying.

The controller LCD data screen shows constantly updated information on Voltage, Amperage, Motor and Controller Temperatures, Rpm, and Running Time. The user can ‘toggle’ between different screen layouts in flight.

The hand controller also features ‘Cruise Control’ and a ‘Vibrating’ Alert system for low battery voltage and peak motor temperature.
