Blade High Performance 70mm 12-Blade EDF Unit (AU Warehouse)

Description

If you're looking for high performance and that realistic jet sound in your latest 70mm sized EDF model, then look no further than this high quality 12 bladed unit.

The 12 blade fan moves a greater volume of air to make for a quiet unit with an amazing sound, this is the closest you will ever get to the sound of a turbine without actually buying one!

Molded from 30% FRP with integral mounting lugs, the unit is for use with 28mm EDF motors or those with a 28mm extension and has adapters to suit 3.17 and 4mm motor shafts.

For the best results from this and any ducted fan unit we strongly recommend checking the balance of the complete assembly and eliminating any sources of vibration.
