I am wondering if I really need to install my Saito 1.80 with anti-vibration mounts. A friend of mine has a Hangar-9 mustang with a Saito 220 and it's mounted directly to the beams with no isolation and it does not excessively shake the the airframe. Also, The Fliteskin spinner seems a little heavy and I was wondering here as well what the weight would do to the efficiency of the Saito 1.80? Any thoughts would be appreciated.

Happy Flying!
