I recently retrofitted some FlyLED's to Josh's RV-9A.
It was a bit of work, since we had to also replace the plexiglass wing tip covers. The existing covers had been modified for the Uavionix blade antennas to poke through.
The directions were good. We used the existing wires, but had to rework the connections.
Here's some feedback:
The wiring diagram colors were interesting. The tail light has blue going to the white wire on the tail light, and white going to the black wire on the tail light the black wire just goes to the shield.
The instructions do say to be careful where you drill for mounting, since there are trace layers on the PC boards. I managed to hit a trace drilling from the top. It would be nice if there were more clearly defined "safe" locations for drilling. Even moving the hole out a 1/8" would have been tight for mounting on the wing tip recess. You can see that there just isn't much room for installing nutplates on the wing tip recess. The boards get trimmed to fit, but you can see how close the LED's are to the edge after trimming the edges of the PC board.
The big resistors on the back of the boards could also be moved inward a bit to make the trimming of the wing tip recess holes easier. You can see where the bottom edge has to be trimmed way down at the vertex. I tried to leave 3/4" of edge to the new cutout.
The ribbon connector between the boards is difficult to trim to expose the wires. The instructions do mention that you can simply use any type of wire here. None of my wire stripper tools could handle this type of ribbon cable.
Lastly, the DB-15 male connector supplied for the control board is a solder type. In this retrofit, the existing wires all came to a spot under the baggage floor where a strobe unit used to be. There was just no way to get down in there with a solder gun. I ended up having to go and get an insertion type DB-15 connector so that I could just crimp pins on the wires. I had to supply the housing/shell for the connector also.
The new nav/strobe lights are plenty bright. The rear strobe isn't as strong as the side strobe lights.
