My v911 doesn't need the o-ring. The mSR and NineEagles need the grommets because the plastic used in their canopy is optimized for weight. So it's very, very thin and flimsy. The grommets helps to 1. secure the canopy to the frame, and 2. to prevent micro cracks around the hole in the thin plastic.

On the v911, we don't have these issues. The plastic used is solid and holds on the frame perfectly secure. Why add additional hassle of putting o-rings. That a flawed design that E-Flite abandoned when they revise the mCX and created the mCX2.
