Cub Scout space derby tips?

Hey gang,

My son has finished his space Derby ship. Got any tips other than balance, and straight fins?

I have some questions...

1. The prop is pulled against the hub by the rubber band. Im suprised it isnt setup to freewheel when the rubber band runs out. Normal? Should i graphite it?

2. Two bands or three?

3. Smaller or bigger fins?

4. What do I use for rubber band lubricant?

Thanks?
