Happy new year and all the best wishes to you.
Hereby some 4" & 5" shell's. Lift was little too low for a reason that's still unclear to me, but other than that I was satisfied about the results.
The year before I used the same lift for the 5", and then they blew right past the moon. One out of three only got to the right altitude now, but the same amount of lift was used on all of them. This shell was one of the heaviest out of the three..
