Look up Radd's school of rotary flight. YOU may be more advanced than most, but the basic lessons should give you a good set of steps to go through, both for learning and reducing the cost of replacement parts. There are also several good sites for setting up the 4 in one and some of the other things that are inherent to the Blades. Let us all know how you are doing. Lots of learning from each other on this forum,
