I am trying to decide what altimeter to buy. I want to convert my L1 rocket to DD and also use the same electronics for a DD L2 rocket (Laser-X upscale). I was planning on using the PerfectFlite Stratologger. It seems to have the most bang for the buck and relatively cheap. But after doing more research I'm not sure. A little more background. I don't have any near term plans for L3, if ever, My main use will be for DD but I would like to have the ability to download data for flight characteristics. I want to fly KNSB sugar motors once I have my L2. So with all that said what does everyone suggest. I know that this could be like Ford and Chevy so please give me some reasons you like your particular choice.
