Wow! 22 seconds is a great time. Try to aim a little higher. 25-30 should be competetive for states and nats.

If a fin falls off when it hits the ground, does it count as a part falling off in flight, or not because it just landed?

[robotman]

i would assume it wouldnt count as the rules say during flight an launch

What do you make a backslider out of?

Is there a good way to attach the fins to the rocket without duct taping the fins directly on? I know this is makes the fins able to move around, so I read that you could cut out strips from another bottle and sand that, but then glue your fins to that. After that you tape it to the bottle with packing tape. This isn't working for me , so is there a better way?

[robotman]

polyurthane caulk/adhesive is a good way to go you would apply it similarly to glue
should be able to find some at your local hardware store

sorry to jump in, but I was wondering how long your bottle rockets airborne... sorry bout that...first year of bottle rockets and not much info...

[Orchdork]

Are parachutes legal this year???

the rules say that there are to be nothing that deploys and nothing to come apart on the rocket.
