Are these the same guys that had an issue with what end of the chute to use last week and needed the colored rings?

David, Launching without turning the transmitter on is a symptom of a greater problem. You must build a routine that you consistently follow each and every time you launch, otherwise you will make this and a bunch of other mistakes. Most of the problems occur if you let yourself be rushed, either by external circumstances, or by a desire to join the gaggle in the monster thermal just off the launch. There are so many ways launches can go wrong that your proposed device may save you from one problem, but the others will be sure to bite you instead. As a reformed sinner myself I speak from bitter experience. Anker David Webb wrote: > Gentlemen, I would like your feedback on something I created last > season in a bit of a whim.
