It does, however, if you are adding weight, that decreases time too. In addition, in some cases, the hole actually increases time slightly. (Faster deployment + more stable) Of course, the size of the hole is something to experiment with. Generally, you want the smallest hole that still makes the parachute deploy fast + remain stable in flight. There're also other ways of venting that you can play with.

Also, is this launcher ok for testing the rocket?

Put parachute directly on the tube, ping pong ball hanging at the side of the tube naturally.donutsandcupcakes wrote: ↑Mon Feb 17, 2020 5:36 pm How do you guys position your parachute on your rocket? I'm using a tube design and I'm having trouble making our parachute release from the tube. As of now, I'm putting the ping pong ball on the tube and the rest of the parachute kinda just drapes over it... Pls help...
Won't that create uneven drag on the rocket, forcing it to tilt to one side?xiangyu wrote: ↑Mon Feb 17, 2020 5:49 pmPut parachute directly on the tube, ping pong ball hanging at the side of the tube naturally.donutsandcupcakes wrote: ↑Mon Feb 17, 2020 5:36 pm How do you guys position your parachute on your rocket?

Hmmm really? Does your rocket use fins? I have huge fins on mine so that might help it? I've never quite had the problem...

At least, that's what's happened to us during practice.
Yes, our rocket has really large fins. The cup holding method seems to work the best for us, but we've tried different risky strats at invitationals to get a higher time (cup holding method takes really long to deploy).xiangyu wrote: ↑Mon Feb 17, 2020 6:42 pmHmmm really?

Yeah, that's right. It seems the most consistent for us but obviously it takes longer to deploy fully.xiangyu wrote: ↑Mon Feb 17, 2020 7:27 pmHmmm what's the cup holding method?
