I am currently waiting on the shipment of a couple f-15 motors from estes. As for the controller it uses an arduino nano, however the flight computer will most likely go through another revision before being flight ready. I've made a video going over the flight computer if you havent already seen it.
Thanks, the system is ready for flight, but is still need to do a static fire test, and test the parachute ejection system. I also need to finish writing the program for the rocket.
Nice job! It seems like the outer gimbal (X axis) would have a very low resolution compared to the inner gimbal. Its using one of the far out holes on the servo arm will would lead to less torque and accuracy but faster actuation speeds. Otherwise, nice job! Looking forward to the flight :)
Torque is one of the issues I'm facing with the x-axis. I was considered doing a small redesign where it could be moved up a hole. I appreciate the feedback
Most of the parts that make up the tvc mount are custom made and 3d printed. As for the rest of the parts including servos, linkage stoppers, and pushrods, I got off amazon. The flight computer uses a variety of arduino components, that can also be purchased from amazon, or on the arduino website. Thank you for the sub
not likely because the metal rods do not undergo any of the forces of the motor. The tube the motor is inside is attached to the rest of the tvc mount by 2 screws on either end, and these screws are the only things structurally holding the tube on. The only force that is applied to the rods is the force it takes to rotate the tube, which is very little. Thank you for the question! I am currently programing the tvc mount for the static fire test planned for this month.
That was a good observation. Though this is not a pid control, the final program will be. Because I will not be using the flight computer in the orientation used in the video, I didn't want to develop a lengthy program around it. I'm still learning, and it could be a while before I have a fully working pid program.
I designed all my 3d printed parts myself and I have not yet released them to the public. Once I test the tvc mount and ensure its functional, I will share the 3d files for anyone to download
The only test I need is a static fire, i ordered motors a while back, but there was a problem with manufacturing. I'm going to order a different motor to hopefully speed up the process. I might charge a small fee of like $5 for the files but that will be determined later
Soooo i am also building TVC Model Rockets but i need to tell you using the little SG90 Servos was a dumb idea they couldn`t even handel an b6 Motor i suggest using stronger Servos
I agree, in recent tests they've proven to be very weak. I've been looking to upgrade them for a while. I plan to change them out with better ones, in preparation for the upcoming static fire. Thanks for the suggestion
I am HS senior planning on creating a TVC rocket later this year as a independent study as a class. Glad to see another person trying the same!!
That's awesome, good luck!
As with you!
What engine and micro controller are you using/ planning on using?

Nice progress! Looks like your ready for flight!

@@velocitylaunchsystems :)
Nice! About done with a TVC mount of my own, hope you have a good first flight!

Nice progress. You earned a sub.
Where do you get your parts from

Super cool question would the metal beam break under the thrust of the rocket motor
not likely because the metal rods do not undergo any of the forces of the motor.

@@velocitylaunchsystems cool thinking of building my own TVC mount and was wondering if that would be an issue thanks
nice
cool
Fantastic
other than that great job
Hey i just got a comment on the interview video from Kurt Borchardt, who asked: Do you use Euler angles
I responded to him on your channel
That is my fathers channel
Is this really PID controlled? Not PI
That was a good observation. Though this is not a pid control, the final program will be.

Hi again would it be ok to use your design as inspiration for my design. It is the least complex I have seen and seems to work perfectly
Sure, after the static fire I'm going to put the 3d files up for sale on a website I'm building
@@velocitylaunchsystems sweet
make a tutorial on this please, i want to make a tvc system too but i can't find enough info to make one.
Joe Barnard, the r/rocketry and r/amateurtvc subs all have great information
Where did you get the 3D Files to print out your TVC Module? 👀
I designed all my 3d printed parts myself and I have not yet released them to the public. Once I test the tvc mount and ensure its functional, I will share the 3d files for anyone to download
@@velocitylaunchsystems well quit "fiddle fartin" around and "getter done!", I wanna build one, and yours looks quewl! 👍
The only test I need is a static fire, i ordered motors a while back, but there was a problem with manufacturing. I'm going to order a different motor to hopefully speed up the process. I might charge a small fee of like $5 for the files but that will be determined later
@@velocitylaunchsystems Well get a MOOOOVE ON! 🤣 I am ready to start learnin the the "flight computer" programmin ssssstuff! 😜😆😁👀👍
Soooo i am also building TVC Model Rockets but i need to tell you using the little SG90 Servos was a dumb idea they couldn`t even handel an b6 Motor i suggest using stronger Servos

@@velocitylaunchsystems Good to hear good luck for ur first launch
Where did you take the rods?
The servo rods?
@@velocitylaunchsystems yes
code pls
Hahaha just try to pass the temperature test. Everything is going to melt.
I plan on lining the inside of the tvc mount with cardboard tube, or printing it in ABS plastic
