My T-Rex 500 is complete. I picked up the servos this morning and finished installing everything this afternoon. I added a CC BEC-Pro just for peace of mind.

The wires are all routed neatly. The power lead to the BEC here is well clear of the motor, though it is hard to tell from this photo. Positive lead from the battery is on the left of the heli, and the ground connection is on the right. I leave the ground plugged in and the positive lead disconnected until I am ready to go.

Here you can see the positive terminal that is connected to the ESC and the BEC via the Deans connector. I put the male connector on the BEC so that the battery cannot get shorted if the BEC is disconnected for some reason.

The other side. The spare connector hanging near the motor wires is for the ESC's throttle connection to the RX. This is a servo extension cable with the positive lead removed. I decided to allow for a disconnect here so that I could easily program the ESC by disconnecting the receiver here.
The wires are well clear of the main gear, but the photo doesn't make this apparent.

The rat's nest. The heavy gauge red/black pair runs down to the BEC. I am utilizing the Bind/Data port to power the receiver and servos. The second connector from the BEC is plugged into the gear channel of the RX. I added the data line for the gyro gain to the connector for the BEC.

All ready for the maiden. Swash plate leveled, all servos properly adjusted for direction and travel. Gyro direction verified correct. Had to reverse pitch in swash mix, everything was working with cyclic control, but collective was backwards. Oops.
I spun her up just to check for vibration and and tracking, and she was pretty steady on the ground. Tracking was also spot on to my amazement. There is a noticeable popping sound when I add cyclic, and I assume that this is an interaction between tip vortices in the main and tail rotors; fun stuff, my 250 never did that!
