I want to thank you for your video and information. My daughter took your suggestion and 3d printed a blade similar to your specification on your edit section. She was told her design was one of the, if not the fastest one in her whole regional division. She even went on to medal at the states level (of course with a lot of extra studying as well since the design was only 50% of the category). Thank you again for the very informative video
I have a question. Me and my partner are doing Wind Power in 2024, and we are not sure of what DC motor we are supposed to use to test our turbine, or some other things. Can you please specify some of the things including the DC specifications and some of the building parameters, as well as some of the tips that you used? Thank you so much!
Hi! Would it be possible to know the angle of the balsa wood? And does the cd radius matter? If the maximum radius of the design is 10cm, can the blade be 10cm? Thanks!
What type of 3d printing did you use, did you use fdm or ska. I’m trying to replicate your design with my fdm printer for school, and I am just not able of achieving a smooth surface like what seems to be yours
Careful hand sanding PLA can give a very smooth surface. Power sanding can easily melt the plastic if not very careful. Start with 150, then 220, then 330 grit sandpaper.
Balsa is really light and easy to sand, usually has a foam-like texture (I was on the event last year and tried out some balsa designs). If you're looking to find something like it, I recommend looking at a nearby hobby store. They usually come in sheets, but make sure it's the right size since it's not measured in metric!
I have a question my partner and I are doing wind power event, and Im wondering if the Manilla Folder blades are drag or lift based, and also the measurements of the blades. Thank you!
I don’t know if this helps but in the description it says that lift based works better… you might also want to read the description too see if their is more helpful stuff
@@ephi1440 They edited their description... they say that drag based blades with very little curve can generate much more power because there is little air resistance. We are yet to try it out but it sounds like it makes sense
I'd recommend doing what I said in the edit in the description of the video. If you aren't able to find something rigid enough, then either balsa or the "States Design" with 3d printing would be your best option.
I am doing wind power for 2024 and I was wondering how did you sand the balsa wood and also what were the measurements? Also what did you use the support the balsa wood? Thanks !
Alex Pyo The balsa design used competition grade balsa that was approximately 1/8" thick. Regarding width I don't remember exactly but it was likely around 4 cm at the root and around 3 cm at the tip. Then it was sanded into an airfoil.

You should read rules 🎉
what material would you reccomend making the blades out of if you don't have a 3d printer available (like, what easily accessible materials)?

Do you have the 3d print link for this?
how were the manilla folder blades? I don't have access to a 3d printer and I want to use Manilla since I have more of it available than balsa wood.

maybe he sanded it

Hey! I was curious how heavy was the wooden one at the end?? Me and my partner are doing windpower

@@Fr33Candy10 thank you so much I’m doing this topic this yaer
does anybody have the 3d model for the drag based design that he mentioned I have no clue on where to start with the 3d printing
If it is alright, me and my partner want to build the 3d printed blade design so can you send us the zip. File. Thx a lot
Are there any rules for design or materials used for before state competition and after?
Does anyone kown what site did he used for the 3d moduleing?
Could you please put in the dimensions for the Manila folder blades?
Could you possibly link the cad to any of these
did u get any
What would you recommend for length on the design you put in the edit?
Quick Question: How did you lift the blades for the balsa? Could you explain the process??
you add balsa

So did the balsa wood work the best??? Please reply soon! I’m watching this for school!!!🙏🏼🙏🏼🙏🏼

What are the measurements of the
Balsa wood model?
14 cm long, ~4 cm wide. Sanded into an airfoil
I am doing wind power for 2024 and I was wondering how did you sand the balsa wood and also what were the measurements? Also what did you use the support the balsa wood? Thanks !
can you add the 3d models here?
do you have some stl files
or are there any similar availible
I’m doing this in state 2024🎉🎉🎉
can you tell the exact lengths??

by the tip do you mean the end of the blade?
And can you also tell me the length of the blade please??
And also no offense but in the video the blades look closer to 1/4" thick.
Alex Pyo yes
what's da resistence?
Gary Song unfortunately it's impossible to tell due to the internal resistance of the CD drive
It looks like none was applied. The rules state there has to be a 6-25ohm resistor between the leads (2024 at least). @garysong8342 @@varunjindal8
