from what i have seen the parlor copter is doing better than the wright bat, but how the copter flies all depends on how its made an not the design itself so i would suggest making each one and answer you question with your own experience to get the best answer.

You can have a very poor design that's built and trimmed well do bad and you can have a very good design that's poorly built and trimmed do bad. Idealy you would want a good design thats built and trimmed well.

I don't know too much about the wright bat but i believe the parlor copter is a better kit (not exactly design).

i agree. even built properly the wright bat just seems too unstable for a competitive environment.

From my understanding, there were a couple of Wright Bats at Nationals and they just didn't compare to the other types.

In a double-rotor design, is it better to have the fixed rotor positioned on top or on the bottom of the motor stick? Also, would a square motor stick work just as well as a rolled motorstick? Relating to the previous question, will a square balsa wood work or is it too weak, and a bass wood motor stick will be stronger?

That's for you to find out (;
Its too early to have a clear answer to that. Experimentation and good design planning is key to winning since this event since it's relatively new.

Under last years rules, yes (is the short answer). Basicaly the weight limit is high enough to allow you to use a solid motor stick with no obvious disadvantage.
Relating to the previous question, will a square balsa wood work or is it too weak, and a bass wood motor stick will be stronger?
Basswood will be stronger (and MUCH heavier) but the correct balsa wood is strong enough.

By correct balsa, do you mean in terms of density?

Density, cross sectional dimensions, and grain play into stiffness of balsa. Some experimentation will be required to find the right piece.
