my thomas 7 watt UHF booster with yagi and 1.2G lawmate receiver with 13dbi yagi on my badass tracker controlled by RVGS tracker GS 4s 16.8v max worm gear drive motor for tilt can handle up to 20 lbs of antennas and gear

Yeah, a minute is a long time to leave the cockpit. I assume you switch to either FBW or autopilot. Still, I like knowing what it is doing. The dual layer disks have a 50GB capacity, so should be interesting. I bought some disks here in Russia, before I knew what different abbreviations meant, so now I have a few spare RE disks.

Went out and played with my RVGS1 I'm very happy. I'm not happy with the mechanical side of the tracker. I'm using the eagle tree tracker that rmrc sells and it just doesn't seem up to par. The only real problem I have with it, is the pan "lags". I'm not sure if is the weight. I have an 8dbi patch, an omni, 2 rx, the RVGS1, and a 2200mah. It just seem the servo just does not have to power to keep fine adjustments. It works to a degree but not to my standards.
I really wish I could buy the MFD/Skylark mechanical side of their tracker. Thank would be a dream.

Depends on what you mean "lags." Remember, the OSD will report where the plane is, encode the data into the video stream, push that over to the VTX which will broadcast it to the VRx that will be fed to the RVGS, who will decode the video, perform calcs on the data, direct the servos to rotate the antenna to the point where the plane WAS, which has since moved to a new spot in the sky.
Granted the above will all happen in milliseconds, but still there is a lag and if the plane is travels across (left to right or right to left) there will appear to be a noticeable lag.
If you have ever held your camera up and wiggled your hand in front of it, you will observe a noticeable amount of latency.
Since we are usually flying in and out, the lag will not be a problem. Also, the lag going across will only be noticable when flying in close, which will not be a factor when flying further out. This assumes you have an omnidirectional antenna for close-in support.

Have you adjusted the speed of the P+T servos to max?

It just feels unsecure. I'm thinking I might go with a servo city setup.
Alex, will the tracker work with a 360 pan system?

As long as you have a potentionmeter that supplies servo position feedback.
5K Ohm pot.meter will do that, with the PWM between 1000 and 2000 (1500 being neutral).
Servo City has a setup that does that..

I'm sorry I mean continuious turning so the antenna doesn't have to "flip sides"...
