Does anyone have any photos of how they have mounted/secured the Featherweight tracker to their rocket? Do you have to have an ebay or payload section?
Here's my reasoning for putting the GPS/Tracking in the nose. If the tracker is necessary mass it makes sense to put that mass where it would be useful. Putting the tracker with the battery in the nose brings the GC forward. If the nose isn't constructed with CF of course, it's a good place for the tracker antenna.
Here are a couple photos showing my standard arrangement. The good thing about having a tracker that attaches to a shock cord is that it would be easy to move to other rockets. But, I typically use two different sizes of aluminum u-bolts. And I use coupling nuts on the u-bolts with all-thread (aluminum, titanium, and nylon). So, the sled with the GPS can be moved to different rockets.
I do just about all the prep at home including packing the parachutes and installing the nose coupler on the forward parachute section. I connect the battery and turn on the GPS (and CommSpec when I'm using as a back up) and install the nose with bolts or screws just before installing the motor and taking to the pad. Also, I can check the signal on the trackers before installing the nose.
