Can someone give a summary of the 101,202, and 404 blades. Supercedures and differences and compatibilities. Availability and costs(I know the factory is trying to get a batch of new I presume 404 blades done at 18,000 set gulp).

Okay sure would be nice if someone chimed in here but I'll put in what I know. If anything I post is wrong feel free to correct it. The 101 blades were lighter and non foam filled. Helicopters with the 101 blades had a lower maximum gross takeoff weight. The 202 blades were foam filled and bonded with a certain type of adhesive. Heavier than the 101 blades. Higher max gross weight was/is allowed with these (202) blades. The 404 blades are identical to the 202 blades except with different foam filler and adhesive used to bond the blades. 202 blades CAN be converted to the 404 blades by the factory. Legally though you cannot mix and match 202 and 404 blades. That is if you just need one blade you can't put a 404 with two 202's or one 202 with 2 404's.
