Hirobo HI0404677 Fuel Tank Rubber Cushion for RC Helicopters  [HI0404677]

Fuel tank rubber cushion

This Hirobo replacement cushion is an RC-scale rubber isolator intended to sit between a fuel tank and its mounting points, reducing vibration transfer and protecting tank surfaces from abrasion during normal model operation. The part is a simple elastic spacer designed for common mounting layouts used on Hirobo helicopter series.

Installation is straightforward: position the cushion at the tank-to-frame interface and use the existing mounting hardware to secure the tank as before. The cushion’s role is to provide compliant support, helping tuning by softening high-frequency vibrations that can affect fuel pickup and tank fastenings.

Compatibility follows Hirobo’s common parts grouping for helicopter models, specifically listed under Common Parts For Eagle/Freya/EX/SX, and it should be used only on RC helicopter fuel systems where a rubber mount is appropriate.
