Which Motor is Best for Your Rocket?

- www.ApogeeRockets.com - When you take a look on the Apogee website at any particular rocket kit, you see a long list of compatible motors. It can be daunting to figure out which one to choose for your first flight.
This week, we go through those motor lists. We explain the important variables listed on the charts and what you can take from them to make an educated decision on which motor would be the "optimum" for your rocket and goals. We'll go through how to make an easy choice, and what factors should go into your decision making for those more complicated projects.
This same information can now be used for selecting a motor based on the long list of motors that RockSim v10 says would be appropriate for your own rocketry designs.
The rocket shown in this video can be found here: www.apogeerockets.com/Rocket-... - Наука та технологія
I usually start off with ThrustCurve then RockSim to fine tune the decision. Its a function of stability off the launch rod (what size of launch rod or rail and rail length), desired altitude, desired visual effect (slow long burners are a delight to watch and film), rocket mass, CP/CG locations, determine optimum ejection delay, wind conditions AND how far do I want to walk!!! Flame colour for me is a secondary choice.
If I can get a long burner on a long launch rail to get the rocket to the desired altitude; then I am satisfied that I've selected the optimum motor. 😎
There was this one time I launched a rocket and it flew off the pad and hovered in place above the pad. It was cool to see but it did end up in the dirt, No harm was caused because it was 5ft off the ground.
Company's like this are the ones that help DIY Model Rocket Builders , Thanks apogee for the support , keep it up
thank you Frencho
I've been 3d printing all my model rockets but your videos still really help so thanks :)
You guys are always great diliver. Thanks again Dear Tim for the great video.
This is very helpful to beginners like me 🙌
:) good video tim!
great video very helpfull
So the burning question is, which is better composit engines or estes engines?
They are both equal in my opinion. They both work great, and they cost about the same too. Motors should be selected based on your mission for the rocket. We have videos on selecting motors, such as this one: ua-cam.com/video/DEg1xnaL0k0/v-deo.html
@@apogeerockets I'll check it out. 🤠👍🇺🇸
Helps😊
Great informative video. My mission is to go out and have safe fun while flying rockets with my son. :-)
Definitely lol
What size motor you use depends on 3 conditions: Size of the field, Wind speed and for Mid/High power, ceiling height
That's why we use RockSim. It take account all that information and a whole lot more.
Building an Estes Star Orbiter rocket for my child. What is a good Aerotech motor for an impressive off the pad launch, smoke, sparks and all? But not super high altitude for recovery. 29mm
That kit isn't one we currently sell. You'll have to run the simulations like we do when we create a motor chart. It is only 3-clicks of your mouse, so you can do it. We're here to help.
@apogeerockets many thanks for quick and thoughtful reply. Great channel, indispensable information for sure. 😊
What about sugar engines?Are they legal?Can they be uses instead estes engines?
hi-point they are not part of model rocketry. You have to have a Level 2 NAR or TRA certificate to make your own motors. Estes is very good for the motors so stick with those
@@colinkaul8324 That’s a total lie! You can definitely make your own sugar motors without any “certificate” 🤦♂️
go for it, trying to make your own motors sounds fun, gonna be trying it myself this week
@@colinkaul8324 that's absolutely not true. If you want to launch at a TRA/NAR facility you need certs to fly your own motors, sure, but any Joe-Schmoe can build a motor in his garage and launch it on the back 40 without any legal issues, until you start getting into the bigger stuff anyways. Transport and sales to others is a no-go obviously, but there's nothing illegal about making and using your own motors. I build my own APCP motors at home and test them all the time, but I've never been a TRA/NAR member. I don't launch anything I'm not cleared to by the FAA or anything, nothing above a Class 1 rocket but assuming you stay within those guidelines it's perfectly OK to make your own propellant and motors.
How to put an engine in and flying with no engine hook and no engine blocker
I guess you'll need to put one in.
I'd use a very tight friction fit if you are okay with the possibility of having a malfunction. If not, install both.
The bigger the better.
