It is a tiny Inductor.. not a capacitor. The tiny Inductor is part of the stock drones on-board Inverted F antenna design.

Also, there is only one "leg". Transmit and Receive are on the same RF trace-line. The Atheros WiFi Chip internally switches back and forth between transmit and receive mode.

Purchased my wheel mod and the installation from Garrock just now!!!

Will be sending my AR.Drone out this afternoon. It says that it SHOULD get to him tomorrow (Wednesday) so hopefully he can get it sent back out Thursday, and then I should have it back on Saturday.

I decided to do it now instead of waiting because the wind isn't supposed to be anything less than about 15 MPH for the next few days...and although I can fly the AR.D down low in those types of conditions, I'd rather not fly it.

Instead, I will use this down time to take one of my trail trucks out to the trails and do some trailing!!!!

My AR.Drone 2.0 is now making the trip to Garrock's to have a new antenna installed!!! It should arrive at his place tomorrow, as I opted for the overnight shipping in hopes of getting it back as soon as possible!!!

Nice!!!

That means I should definitely have it back by my days off next week. Hopefully the wind won't be such an issue next week.

My AR.Drone is slowly becoming more and more capable.

WiFi repeater
Wheel Antenna
60Beat
GPS Flight Recorder

It's now to the point of having many of the same features that some of the less expensive "higher end" quads.

I've been really thinking about buying another quad to control with my DX6i, one that would be able to carry a GoPro and use a FatShark for FPV...but then, I think, my AR.Drone does pretty similar to that already, and I've already got it.

I got mine back today.

Quick testing yielded positive results, but it was dark so I didn't want to mess with it too much.

I had several instances where the signal dropped significantly all of the sudden, yet I maintained complete control. I also noticed that from one particular angle, the signal would drop as well.

I THINK that most of this was due to where I was flying. I was staying low, about 8 feet, directly over the pavement. Basically, I was flying down the road at 6-8 feet of altitude to make sure that I could track where the AR.Drone was going, as it was too dark for the camera to register what it was doing.

So, I'm thinking that the low altitude coupled with the fact that I was over the pavement in a neighborhood where just about every house has WiFi is what caused the couple of signal drops. That, and I'm not sure how good the WiFi antenna in the iPad Mini is.

Anyways, I had been able to record about 150 feet of range regularly with just the iPad Mini and the stock AR.Drone. Tonight I was able to get out to 125-175 paces with total control. I've measured my pace at 2.5 feet, so that means I was getting out to 400 feet with total control of the AR.Drone. I had enough control to spin, flip, and then land before marking off the paces to figure out how far I had gone.

So, with just the wheel mod, I more than doubled the range. Now I need to get it to the park so I can check the range when not worrying about the darkness, get it up a bit higher (no telephone lines), and then test it with my repeater.

The only thing that had me a bit concerned was those sudden signal drops, but like I said, I think it was a combination of the things above...and I still had control, so I guess it's not that big of a deal.

Leave it to me to be late to the party but I got back my modified mainboard from garrock today and plan to do the install tonight. The soldering work is top notch... far better than I could do myself.

Here are a couple shots post mounting. I will very likely be getting the same service done on what was my "primary" mainboard. Initial test flights were very promising, easily out distancing a handful of "benchmark" locations I've used over the past couple years on my property as problem spots.

My apologies if this has been asked and answered before. I did not take the time to read the entire thread.

Any plans to offer this upgrade for V1 drones? I have a V1 I'd be willing to turn over for testing.

If you have an Android Device then download a WiFi Analyzer App. Run the App and hold your device about six inches or so away from your chest and slowly rotate to identify the strongest signal direction. Then walk in that direction. Has worked every time for me.

======================

I've got a kick out of helping many over the last year fulfill their goals; which is really the Fantasy of Flight vicariously viewed through the drones video downlink.

It would be interesting to hear how things have worked out for everyone.
