Sand Shark AH-1F Cobra V2

Smoke system for gun barrels

May 26, 2025

Since I've been making these systems for others' Cobras (Roban, Vario, LM, Alterbaum), it's time to put one in my own. This bird is already jam packed with electronics (animatronic cockpit and sound system), locating space for the smoke tank and pump was challenging in a narrow fuselage. Because of all the added contraptions in the nose, this model has the unusual problem of being too nose heavy. In order to achieve a better cg, the lipos have to be located rearward, standing vertically in a side saddle configuration. 2x 3d printed L brackets attached to the side frames allow the lipos to be strapped tight using hook n loop straps. The nose area is now free to house an rx battery and miles of cables and electronics.
