Re: Tweaks for 2021

IMO only increased stab area is needed to make planes easier to trim. Would be interesting if they gave us the option of a "biplane" stab config with the current dimensions. Even though it's a pain to work with, I think a larger prop would just make times longer, which is the exact opposite of what ...

Re: Ping Pong Parachute B/C

I've been testing with the Nerds Inc Model Z launcher and we've been having a problem with launcher consistency. At higher pressures (>30 PSI), the U-shaped pin does not pull out enough to release the bottle, perhaps due to the higher friction force between the pin and both the bottle and the metal ...

Re: Wright Stuff C

I'm using a standard Ikara propeller. Only modification was that I took the plastic part off the "hook" Would that make a difference? If you're using Ikaras, I'd recommend bending your own propeller shaft out of straightened 0.020" music wire. With two needle nose pliers and a bit of practice, it's...

Re: Ping Pong Parachute B/C

Would 3D printing a "shell" to contain the ping pong ball be legal if the strings from the parachute are still attached directly to the ball with tape?

Re: Rule 5c

I do it with a sharpie. Do NOT press too hard. It'll take a while to do it correctly but do it slowly. I used to do it with spraypaint, with sectioning off the rib bay and spraying from 2 or 3 feet, but that, unfortunately, doesn't seem to work anymore with the rules. Light pressure, go slow. I dar...

Re: Gravity Vehicle C

As for ramp surface materials, I think a stiff-ish vinyl material could be good depending on how you implement it and attach it to the base of the ramp. I know previously my school used a wooden base and acrylic for the surface material which seemed to work well. How did you manage to bend the acry...

Nope its a literal tube. :)
How does that work? Rolling balsa sheet? Just getting an extra light balsa dowel and screwing a hole in the end?
Yeah, how do you connect tube with tensions?
