My intent here is to share my experience, not to leave negative comments about any brand/label. Everyone biz in HPR is small and home-grown with good intent. TFR gets ugly all too often and I don't want to add to that.
Yes, the only thing left of the sled was the eyebolt. My sled did not come with FG reinforcement. Don't know if this changes anything, but I bought one of the first units available. That said, I don't think I will trust plastic to this task in the future, with FG reinforcement or not. And, lesson learned, I will never launch a GPS tracker without a lock, redundant or otherwise. The launch congestion and timing at RED GLARE compelled me to move along as is--$150 lesson. A new Featherweight GPS tracker is on the way.
Reason why I had a tracker GPS lock problem was that I didn't connect the ground station/phone until after it was secured in the rocket, shear pins in place and all. When I did, the app immediately took me to a firmware update without an option to skip. That didn't take long, but the ground station required a recycle of power afterwards to function. I did not open up the rocket to do the same for that tracker. I wish there was an option to skip a firmware update, perhaps reasserting the update option every time the app is opened.
Just to be clear, the reason the tracker was lost was entirely mine, not Labrat or anyone else. We need Labrat rocketry and all of the other home-grown businesses that keep our community thriving. If I'd opened up the rocket and recycled power on the tracker, it likely would have been found.
The tracker sleeve I use for my BigRedBee HAM units was bought on Rocketry Planet years ago and has flown dozens of times without a fault. It is made of 1.5" tubular nylon webbing with sewing to allow the unit to fit inside snugly, with a cord at the top to connect to harness. I just bought 2" nylon webbing, grommets and kevlar cord with the Featherweight GPS unit in mind, and think it will work just as well. I am also considering a 3D printed exo-skeleton for the tracker to snap into before going in the sleeve, to minimize potential impact damage. Work in progress.
