I flew some Estes rockets in a park in Riverwood a while back, and nearly lost the smaller rocket to the M5 when fitted with the largest recommended engine. I had cut out the apex of the canopy (as recommended in the instructions), which helped it to come down faster, but it was pretty close. (I had made an alignment jig to get the fins straight, filed the leading edges, and used the bare minimum of paint, so she climbed pretty high; we lost sight of her for over 30 sec.)
It would be good to know how to estimate how big the rocket range needs to be based on wind speed and glide ratio for the rocket. Are there any available data on glide ratios for parachute-recovery rockets? For that matter, is there any public source of timely data on wind speed versus altitude (e.g. from Bankstown Airport)?
I just found a nice big space in Heathcote, but it's only 350 m long (including the Oval), so it would need a dead calm day, I think.
