It has been many years since I built and launched rockets.  This is fun.  On a couple of the launches the parachute did not open.  Basically a streamer return.  Not a problem for this rocket.  Small with sturdy plastic fins.  May cut a hole in the parachute to see if that will keep it from drifting so far when launching with the B4-4 engine.  As soon as I find a calm day I want to see what happens when a C6-5 is loaded in the back end.
