This is an alternate ESC/BEC mounting plate for a Century Swift NX 550 electric heli. It's made specifically for a HobbyWing 80A HW ESC. The HobbyWing ESC won't fit in the normal place for the ESC and there isn't a clean way to attach it. This provides for bolting the ESC to the Heli with real screws and captive hex nuts. It has a pretty big space for BEC so you can use what ever you want.In the picture attached, the mount is upside down and the nose is to the left. This mount places the ESC behind where the ESC normally goes.I used Replicator 0040 with Sailfish and printed it with accelerated settings and at 150micron layer height on my Replicator Dual.Print it out as shown in the picture, using exterior supports. Once printed out, use M3 x 14mm socket head cap screws and M3 lock nuts to attach the ESC to the mount. The BEC (pictured to the left in the picture) is attached with double backed sticky tape. The whole shebang is attached to the Swift NX with full sided servo wood screws or equivalent.
