The new
Auri Electric F5K F5K is a high performance electric DLG type model for the nascent F5K class. The Auri Electric has the excellent performance and the gentle handling characteristics of the discus launched glider version. This model is based on the Auri DLG with the nose cut off, a nicely profiled firewall and a new fin but otherwise it is identical to the pure glider. The firewall (not fitted) is designed to be installed approx 12 mm back front the nose to allow rear mounted outrunners to be fitted. Alternatively a Electric DLG CNC Motor Mount (not included) can be used to very easily mount the motor.
The Auri is ideal for customers looking for 1.5m electric F3K type glider with good performance, nice handling and model toughness at reasonable cost. The fuselage is a one piece design with a generous front to facilitate fitting a small powertrain and all servos. The tailplane (horizontal stabiliser) and fin (vertical stab) are very light and have a good finish. The rudder and elevator are ready hinged and give good control response.
The wing is beautifully molded from spread carbon with a Rohacell core to maximise strength and dimensional stability, ensuring the surface finish stays smooth. The design incorporates nicely designed ailerons to give excellent control at all speeds. The hinge gap is sealed with hinge tape, eliminating a common drag source and ensuring high launches.
The supplied accessories include a firewall, servo mount, tail pylon, aileron pushrods, rudder and elevator pull cables, torque springs, and all control horns. In order to balance the model without tail weight the nose will need to be kept light, with a lightweight 300-400mAh 2S LiPo and lightweight servos. The model is supplied with a servo tray for 4 pcs KST X08 servo but we think that 4 pcs KST X06 are more appropriate for this model.
