I was at the local LHS yesterday and was made aware of a problem. I purchased a nexus for my son about three weeks ago and the owner of the LHS showed me a notice he received on the nexus blade grips. IT said that they had a problem and could come apart thus slinging the bladeand it said (DO NOT FLY) until the grips are replaced. The amazing thing tp me is I was told that the new grips would mont be available for a couple of months. I will now get ahold of the shops disributor, they can either come up with grips or they will own a Nexus. The bad part is they are still selling the kits with the bad grips.
