When I first started back in rocketry I did a lot of simulation stuff
with Rocksim v5 but I kind of stopped simming and just flew things and
designing by eye for quite a few years. I'm thinking about a level 3
project now and will need to do some sims again so I'm wondering if
it's worth upgrading to v8 before I both. Is there anything that v8
offers over v5 for the kind of simulations you need to do for a L3
I won't be doing big, fat, heavy rocket on the smallest M motor I can
get either so I'm interested in accurate supersonic drag models,
accurate high altitude atmospheric models and ideally being able to
predict likely downranges for the recovery phase.
It's good and for the animation of a flight, one can now stick a jpeg in
the background and enjoy the entertainment. I took a shot of my favorite
launch site and used that.
Only disadvantage is that you cannot load it on more than one machine at
a time. v7 one could do that and I even have it running under the wine
emulator in Linux.
With that in mind, I definitely WON'T be upgrading to v8 -- I keep it
installed on both my laptop and my desktop, so I have the ability to run
sims in the field. Tim even approved my doing so when I first bought
Well, I just upgraded to v8, and -> NOTE: To install this software, you will need the unlock code
-> that is supplied by Apogee Components. If you placed your order
-> using our online store, you should have received an email order
-> confirmation. At the bottom of that email is your unlock code.
-> The unlock code will only allow installation on a single computer.
-> If you need an additional unlock code for your second computer,
-> please ask. We'll be happy to provide it.
So, it appears that this isn't a problem.

Interesting, I did write them and state that I was concerned that if I
gork my machine or if I want to move it to another machine I would have
a problem. I received an email that I can uninstall v8 and the
appropriate information will be sent to their server and I can reload it
on another machine. I would have to use the v8 uninstaller
I was under the impression that the license was good for one computer
only. If what you say is correct Rick, that would be a pleasant result.
In my opinion v8 has more eye candy. Don't get me wrong. It is a much
cooler program than version 7 but 7 still gives you good calculations.
I have to admit, I haven't explored v8 to its' fullest extent but that
is only because I'm not able, at least up to now, to have it on my other
computers. Both versions give a rocketeer valid information on
potential flights and it has saved me from some devastating failures.
For instance, became a BAR last September, worked all winter on an Estes
Mean Machine where I fiberglassed the tube with resin (no cloth, my
mistake). The ship of course was heavier than normal and I was going to
use a D12-3 or an E9-4 for the test flight. Rocksim questioned the
stability off the rod and suggested an F21-6 would give me between 950-
1000' of altitude and a stable flight.
Have done three flights on the F21-6 all of which were excellent and I
have only had a problem with the fiberglass resin comig off of the body
tube in a couple of small spots. I didn't sand the tube well enough for
applying. Can fix it in short order.
I have somewhere between 75 and 100 hours of my time invested in the
ship and the paint job. It made Rocksim well worth the cost.
Tried it on my mac the other evening...
The mouse sensitivity made designing fins impossible. That and the
program simply wouldn't run -- Something about permissions....
I see they've added all sorts of generators to try to mimic mother
Wish they'd bite the bullet and turn it into a full 6dof program that
can handle crosswinds.
Uninstalled the demo and went back to using V5...
I recently bought V8 and installed it on my PC at home. I've also
installed it on my laptop. I simply emailed them, told them I wanted to
install it on a 2nd machine and they sent me another unlock code
