Which Motor is Best for Your Rocket?

[@upekshawetthasinghe906]

Company's like this are the ones that help DIY Model Rocket Builders , Thanks apogee for the support , keep it up

[@apogeerockets]

thank you Frencho

[@Roarmeister2]

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. 😎

I've been 3d printing all my model rockets but your videos still really help so thanks :)

[@sweaterdog5475]

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.

[@Workerbee-zy5nx]

So the burning question is, which is better composit engines or estes engines?

[@apogeerockets]

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: kzbin.info/www/bejne/enbKYquklrFjoZI

@@apogeerockets I'll check it out. 🤠👍🇺🇸

[@jodigant]

You guys are always great diliver. Thanks again Dear Tim for the great video.

[@skipparet6800]

What size motor you use depends on 3 conditions: Size of the field, Wind speed and for Mid/High power, ceiling height

[@apogeerockets]

That's why we use RockSim. It take account all that information and a whole lot more.

This is very helpful to beginners like me 🙌

[@PatrickWilson47]

Great informative video. My mission is to go out and have safe fun while flying rockets with my son. :-)

[@GreyLightning]

Definitely lol

[@inex4431]

:) good video tim!

Helps😊

great video very helpfull

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

[@apogeerockets]

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.

[@brandonbentley5453]

​@apogeerockets many thanks for quick and thoughtful reply. Great channel, indispensable information for sure. 😊

[@hi-point5080]

What about sugar engines?Are they legal?Can they be uses instead estes engines?

[@colinkaul8324]

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

[@devilliar3786]

@@colinkaul8324 That’s a total lie! You can definitely make your own sugar motors without any “certificate” 🤦‍♂️

[@mtlfpv]

go for it, trying to make your own motors sounds fun, gonna be trying it myself this week

[@TheExplosiveGuy]

​@@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

[@apogeerockets]

I guess you'll need to put one in.

[@trevorglasgow3120]

I'd use a very tight friction fit if you are okay with the possibility of having a malfunction. If not, install both.

[@normellow]

The bigger the better.
