How to make a stable model rocket

[@godfreycarmichael]

I have been flying rockets for decades and just used this method yesterday and was very pleased with the results.

[@markhatch1267]

I really love it when a complicated problem gets made simple enough that a child can do it! Nice work. Good video.

Article appeared the first time I knew was AMERICAN MODELER about ‘57; thanks for bring back the TECH ! Great tutorial!!!

[@c55427]

Excellent video! The correct way to do this! The note about small rockets and starting them in the proper orientation is such a perfect point!

[@zacharycarter7377]

Used some of this information on a design for engineering class I am taking. Thank you for the content!

[@bernardotech]

Glad it was helpful!

Rocket building rules : full length of the rocket : L= 15 to 25 Diameter nose cone length :Ln = 2.5 to 3.5 Diameter stabilizer swing : S = 1 to 2 Diameter total area of stabilizers : F= 0,7 to 0,8A, Where A=Length*Diameter stability margin(distance between center of gravity and center of air pressure) : k = 1,5 to 3 Diameter

Good rules of thumb, for us not attending MIT.

Brilliant explanation of the center of lateral resistance . Clear and precise well done sir !

[@devincherry6891]

I hope you don't mind but I'll be using this video and a screen grab or two from it in my model rocket lab instructions for a high school astronomy class I teach. Thanks a lot for putting this out there!

[@bernardotech]

+Devin Cherry I don't mind at all. I'm glad I could help.

[@lukeb5905]

Thanks. About to try this on 25 lb 6" diameter scratch build.

[@CheckThisOut77]

Good to include the weathervane example (particularly the side drawing showing the larger section behind the pivot point).

[@ramjet54]

Thanks! This explains it better than anything I've seen so far. My rocket is now stable! Had to add extra fins but it worked.

[@bernardotech]

You're welcome - glad I could help!

[@elitenetworksllc4378]

Most informative, concise video I've found. Thanks.

[@jessecilliers4922]

extremely helpful for my physics assignment! Thanks very much.

[@ArgenioAndrew]

Thanks for the helpful video.

[@steffenleo5997]

Great stuff Well explained...thanks sir...👍👍

[@bernardotech]

My pleasure

[@chrisladouceur4093]

Wish you would make more videos like this about rocket design and optimization. Thanks

[@evolutionfilms1]

About the fins...is there a special method to use when designing the fins? How many? What shape? What size? What material? How high to place fins etc?

[@commonsense962]

Thank You

[@bernardotech]

You're welcome!

[@bernardotech]

You're welcome - glad I could help.

[@ibetubinitup]

excellent video! soo helpful and explained very well!! :)

[@bernardotech]

Thanks! Glad you found it useful.

[@MentaIPatient]

Thank you

[@Sportsterglide]

very helpfull thankyou

[@bernardotech]

You're welcome!

Why do you want a weather vane to point into the wind.. A windsock points downwind .. You can make weather vanes that point downwind too

[@coriscotupi]

Because weather vanes are fundamentally different from windsocks in the way they represent wind direction. If you make a weather vane that points downwind, you will be the only person that correctly reads it, everyone else will read it backwards. Of course you CAN do that if you want.

[@modelrc9500]

How about adding a camera to a rocket like the Estes silver arrow like a keychain camera

[@evolutionfilms1]

Thanks sooo much!!!

It's not rocket science!

[@truffleshuffle5861]

Correction this video is more smelly
