This upgrade replaces the stock o-rings (set of two). The advantages of these dampeners is simple. They are able to produce a more responsive and tighter feeling Heli by filling the entire dampening area of the head block with material. The dampeners are designed specifically for the Raptor 90 head block and spindle, giving a tight dampening solution without needing to over-compress the rubber with spacers. Also, because of their shape and material, these dampeners are able to last much longer.

Should your product come with any moudling flash:

1. Poke a small hole in the flash with an X-Acto blade.
2. Push the spindle through the damper stretching the flash onto the spindle.
3. Take the X-Acto blade and cut around the spindle next to the damper.
