I am ditching my terminal strips on my ebays and trying these. These will do a much better job making contact with the igniter wire without breaking it. Nice design even works on smaller 38mm rockets.
The only thing stopping me from giving this case 5 stars is it would be great to be able to mount a switch in the case so I could turn off the tracker easily when the rocket is retrieved. There is plenty of room for the 450mAh battery I use for the tracker plus the mini itself. It even has a window cut out for the LEDs on the mini. While this is great for functionality, it worries me because I will be putting the tracker on the shock cord which will expose the board to the corrosive ejection charge gasses. I am buying some conformal coating for the board which will solve this so I did not subtract from my score.
