ePLA-LW (Lightweight PLA) is a material specifically developed by eSUN for use with Model airplanes, drones, and Cosplay. Compared to the eSun Wood PLA, ePLA-LW has a more stable interlayer bonding process, and the foaming rate and strength can be controlled by adjusting the print temperature. You are also able to use active foaming technology to achieve lightweight, low-density PLA parts. The foaming volume ratio is 220%. At around 210-270°C, this material starts to foam during printing, increasing its volume by nearly 1.2 times, and the printing extrusion rate can be reduced to 45% to print lightweight parts. This means that 1 roll of ePLA-LW is comparable to 2.2 rolls of ordinary PLA. Foaming makes the layered pattern almost invisible, resulting in a smooth surface. 

The use of lightweight PLA enables your model aircraft to have a lighter wing load and a lower stall speed.
