Basics of Motor Selection

Selecting rocket motors can be daunting for new modelers. The engine code system that is printed on the side of the case might seem like it is written in a foreign language. In this week's video, I'll try to take some of the mystery out of it by giving you some analogies that you are familiar with - "driving a car."
When you finish viewing, you'll have a greater understanding of how the letters and numbers are used to select the motor for your rocket.

I think I have some Centauri motors from when I flew in the 70s. Great videos, the c6-5 was the most popular motor back in the day.😎👍🇺🇸

I hate how so many small things can completely change what motor you need. On a windy day, I have to choose a different motor. 1 week later, it finally comes in from halfway across the country and the weather is completely different and I need a new motor which comes in way too late as well.

If it fits...launch it! 😊 Bigger is better!

I just recently bought an Aerotech SUMO. I just completed it. It stand 39” tall and has a 4” diameter. I am new to the hobby, although I have launched 2 much smaller model rockets a long time ago. Does anyone know exactly what model I have built? If so, should I use a “G” or an “H” engine and what type of launch pad should I purchase since it is rather large? I was unable to find videos of someone assembling my exact model and I had some trouble assembling the Aerotech SUMO, because the instructions were not the clearest and neither were any of the illustrations. I feel like I did some steps incorrectly such as the “piston” thingy and the shock cord and parachute installation, which are very important since I want it survive at least one launch and landing. Any help or guidance is much appreciated! Thank you. I need a decent amount of help and I want to make sure everything is all good with the assembly and engines before I blast it off.

This is a great video explaining the designations on a motor, however some rocketeers might want to know how to size a motor for the given weight of the rocket. I have a 12 oz. rocket that takes a "D" motor. When I launch it, it almost doesn't leave the ground. What motor would be right for it?

Oh there will be a LOT of motors you could use. The process of selecting motors will yield a plethora of choices. It is a simple process too, but it involves some software. See the tutorial on how to pick motors at: kzfaq.info/get/bejne/h7maqpmir5OzqoE.html

Hello

@stevesidare2493 7 жыл бұрын

I appreciate the info, but it is a bit misleading. "0" delay has nothing to do with a parachute. There's no chute-popping charge there. And the delay charge is not measured by apogee - it hopefully happens at or a bit after apogee. (Haven't done model rockets for years and I miss it.) Better to prep your videos before camera time so you know what to say and how to accurately say it.

I've learned almost everything I know about model rockets from these videos and got my L1 certification watching these..... I think they are great videos. Not misleading

@@SpeedBallRockz I like these videos. And the data is definitely helpful! That incorrectness may mean a burnt chute for a beginner - not a horrible deal in most cases. Thumbs up on your L1 Cert!

There is no ejection charge for parachute ejection on an xx-0. Get your facts straight before providing this type of info in videos.

Maybe you wouldn't call It an "ejection charge" more like a "burn through" as the thrust reverses directon for a brief moment. This enables the light-off of a second stage motor and the pressure produced helps in the separation of the lower stage. Now there are the plugged engines xx-p that have neither ejection or burn through that are used in rocket cars and rocket boosted gliders.

Actually XX-0 motors do have ejection charges. The last number represents the time delay. Motors with no ejection charge will have "P" instead of "0".
