Someone requested I post some photos of the antenna installed. It pretty much looks like everyone elses but here it is anyhow:
I used 1/4" thread protectors to seal the void where the antenna holes were. Fits perfectly once you squeeze and work them in a bit. SKU #756850 available at any home depot.
To answer the question of the difficulty of the install and any troubles. It's fairly easy and requires basic skills and a basic set of tools. No soldering or anything. I ordered a set of precision electrostatic safe electronics tweezers from amazon (link
here) to perform the install. You could probably get away with a good set of needle nose pliers. I followed the DBS mods tutorial on youtube (
here). However I did mine a bit differently. The typical install takes around an hour. Took me 1.5 hours because I choose to preserve the original antennas in case I ever want to convert back to stock. Doing so definitely made it a great deal more involved but I didn't mind too much. Chuck recommends cutting the original cables and pulling it out of the silicone to save time and to not disturb the ribbon cable. I think that is fine if you are mass producing these modded remotes for customers but on my install I wanted to save the cables. I don't think the ribbon cables are nearly as fragile as he suggests, but that is just my opinion. My antenna cable, unlike everyone else, ended up being sandwiched between the two ribbon cables inside the silicone. Had to cut it away very carefully with a micro wire cutter. Then I had to remove the gimble control knob assembly (1 screw, its easy) and then 4 screws so I could lift up the right stick control module and get the antenna out. The other was way easy just routed it out with the tweezers and removed.
Installed the new antennas, hot glued them down like in the video, drilled the holes, blew out the plastic bits with some canned air (important!), screwed connectors in then put it all back together. My biggest 2 difficulties was removing the stock antennas and getting that darn con cable back up into the little slot hole when putting the case back together. I used my fingers and the tweezers to slide the con cable back in place and flip down the little cover to lock it in. As for the antennas I must have spent 10 mins getting the darn things out. No matter how hard I squeezed the holder together with pilers and tried to pull them out, they would not budge. Had to cut them out like chuck did in the vid but even then it was a pain.
I suppose you can avoid a lot of this trouble and just leave the stock antennas alone, wrap up the cables and cover them and leave them inside the case. However I like the clean look of not having them so it was worth the trouble for me. Good luck.
