It does both so you just need the one altimeter. It is super simple and programming is done with a few switches. It does just the basics and that’s fine in my opinion. The RRC3 has a lot more features and collects more data but is more complex. There is a place for both. I’m not on TRF.
@@WalkerSmallEnginePerformance Ok, does that do the drouge and the main(and do you need one for each then, or one does both? I should have asked above?)?I'll check out RR3 too, im not sure the difference but getting back into this im learning. My JL chute release has been great too, and OpenRocket...I took a break for a long time and now I'm finding all this for the first time just recently, lol. Didn't have one rocket in May, now going for my L2 hopefully this year has been very nice. Great video!! Are you on TRF?
