Due to some questions and some concerns on RockSIM limitations, I wanted to make everyone aware of these Q&A's, There are more on the contest page, but these are significant for design. I have received 2 designs and am working through these issues on those two right now.

Allowable Motors:
Estes Motor File for RockSIM <link on site>:
Booster 18mm - C6-0 or B6-0
Booster 13mm - 1/4A3-0; 1/2A3-0; A3-0; A10-0
Sustainer 18mm - 1/2A6-2; A8-3,5; B4-2,4; B6-2,4,6; C6-3,5,7
+ I'm a little confused about the rules for the the diameter of the
sustainer section...
--- Yep, I really lost people on this one. The idea is that the tube is
selected from the database, so in my example above I chose two tubes, 1 for the booster and 1 that was at least 1/2x the diameter of the booster tube (meaning 1/2 or smaller). For the other one I chose two tubes, 1 for the booster and 1 that was at least 2x the diameter of the booster tube (meaning 2x or larger).
+ Do you have to use "real" motor combos. For instance, Rocksim will let you use a 1/2A6-0 18 mm booster engine for the low and slow, even though no engine was ever produced. Do you have to limit the 18 mm booster engines to C6-0 and B6-0?
--- Yes, for the cases that you choose the motors, they must be "real" available motors. EXCEPTION: see below, all 13mm in booster will be set to 0 delay.
+ I just went to the 2003 Estes catalog and found there were *no* -0 mini motors. When you select a motor with a delay in the booster, my sim goes nuts and assumes ejection occurs in the booster. So, can we use A10-0 or 1/4A3-0 in the booster anyways? Pretty much have to. In the real world delayed 13mm motors could be used and eject from the rocket.
--- Yes. This is now a requirement.
