Mine is in the works, I haven't settled on a motor for sure yet but am getting it narrowed down a bit. I'm going to run 600mm blades also with a stretched boom and a speed up gear in the tail rotor. I think I'm going to go with two 4s3p packs and am working on modifying the radio tray right now. I am going to get rid of the stock tray and do away with the mechanical mixing and do a ccpm mix instead. I think this is also going to be necessary to allow for the battery mounts that are going to be on both sides of the machine. Hopefully by the time I get this project figured out I'll have settled on the motor and Castle Creations will have their high voltage controllers ready.
