# Level One Certification

I am interested in getting my level one certification towards the summer of this launching season. I know some of the requirements needed to go about this but I am not entirely sure on the whole process. I know you need to be at least 18 and build and successfully fly a rocket with either a H or I motor. Is there anything else that I need to know and how do I start this process?

Thanks,
Redsox15

Depends...Which national org are you going to join? NAR or Tripoli? You have to be a member of one of these to "certify." I would suggest joining the organization that you local club is a part of. L1 is quite easy especially if you've flown lots of MPR stuff. The rules between NAR and TRA for certification are virtually the same just worded differently.

And there you go. Just don't ask which kit would be the best L1 rocket because you'll turn this thread into a 10 page debate.

DAllen gives good advice -check with your local club(s) first. In fact, you've probably already been flying with them and should have a good idea of how and what's expected of members for good range etiquette. Our club strongly reccommends flyers progress thru the alphabet, one step at a time and then the butterflies aren't so big in the belly that achieving said goals come easier.

While alphabeticaly might be ok I went from G80-10 to I284-14 Aerotech. This was back in the confirmation not ceritification days. My rocket was 5' tall, 3" in diameter and weighed 5 lbs at lift off. It did fly on a H242-6 later to a great flight but I wanted to make sure the first time

Of course, you could always purchase a copy of the booklet, "A Guide to Level One Certification" through Extreme Rocketry Magazine. Gee, I wonder who wrote that?

Thanks for all the input everyone! One more question for everybody, does a level one flight require an altimeter? Those I am not to familiar with. To my knowledge, the high power motors do not have an ejection charge, I could be wrong.

Thanks,

Nope. No altimeter required. In fact, most motors in the H and I range come with various delays. It's not until you get into the K and up range (and there are exceptions) that most motors do not come with ejection charges. I would not recommend an altimeter for an L1 flight. Just keep it as simple as possible IMHO.

Rocketry is a lot of fun.

If you want to get into HPR and know what you are doing, you need to do some reading.

A very good reference is Modern High Power Rocketry 2 by Mark Canepa. Also the links in post #2 above. And spend a bunch of time reading through the many posts here and on Rocketry Planet.

You do not need an altimeter for L1 certification.

Most, but not all, H and I motors do have ejection charges.

The Cesaroni engines do have ejection charges and are very easy to work with. I used those for my L1 an L2 cert flights.

It's a good booklet. It helped me with my Level 1 Certification.

Of course, all the information you need to get your Level 1 is available online and you'll receive help here and from those in your local club. But, Tim's book gathers all the information into one place. It's easy-to-understand and, maybe I'm old-fashioned, but I enjoy reading about things like this in printed form and I think I absorbed more from reading the guide than I would have from reviewing web pages.

I second this book. It's a good book and could inspire you to try some other things like clusters, two or three stages, and minimum diameter.

I got my level one on a PML Explorer, which was very easy to put together.

Keep the flight low for your level one, because it'll be easier to recover if it doesn't go too far.

Have fun,
Mike

My suggestion would be, don't even consider anything concerning L2, just concentrate on the L1 and don't worry about getting a kit that can do both.

The suggestion for building a L1 rocket that can be flown on G motors is a very good one. Most kits have recommended ranges of motors and most recommended ranges cover three sizes. F-H and G-I are poplular. Some will go even further like E-I range or F-J.

If you don't have any experience with reloadable motors, I would highly recommend getting a kit in the F - H range, buy a 29/40-120 Hobbyline case and have fun and learn a lot with the F & G motors. It won't take long at all and you'll be comfortable with the reloads and stepping up to an H or I motor will seem like no big deal.

The suggestion to find the nearest club and fly with them is probably the best suggestion you'll get. We all love talking about our latest projects and at the club launches you'll find a lot of experienced fliers that will only be too happy to pass on their knowledge and experience, especially if you're willing to sit and listen to a few old war storys along the way.

I have been doing some more research and have found that some H motors come in 29mm as well as 38mm. Am I better off getting a rocket that just holds 29mm or get a rocket that can fly 38s and get an adapter so I can fly 29s as well. So many choices!!

Just look at all the coolio motors you can get here:

Just look at all that stuff in the 38mm size. That alone should convince you to go the 38mm route. Not to mention all the cool G and H 38mm loads that everyone else makes.

My advice is to always get the largest MMT available. As hognutz63 says, you can always adapt down. The larger size gives you a lot more options.

As well as 38mm G through J motors from Aerotech. Plus they have a multitude of loads to fit in each case.

CMASS is your local rocketry club. We have meetings on the first and third Tuesdays of each month, alternating between Marlboro and Saugus on odd and even months respectively. Stop by and we can answer any questions you might have. Check out the CMASS website for details and directions.

Go 38mm. Even if the rocket is fairly light, there are fun motors in the shorter 38mm cases that have very difference characteristics from the 29s, and as stated above, you can always adapt down.

Besides joining NAR or TRA to become high power certified, (CMASS is a NAR club) you also need to have a BATFE explosives permit to purchase a high power rocket motor, or have someone who has a permit purchase the motors and fly under his permit. This is the biggest current impediment to high power certification and why you really need to join your local club.

In general, an L1 rocket should have a 38 mm motor mount and an L2 rocket should have a minimum 54 mm motor mount. You're not going to break any altitude records in Eastern MA if you want to get your rocket back. Due to the coastal breezes, we limit high power rockets using apogee deployment to 2000' to insure an infield recovery at the 300 acre field we rent in Amesbury. A lighter weight 4" or larger basic rocket kit is what you want for your L1 certification rocket as you will want to keep your altitude above ~1000' but below ~1500'. Similarily a 6" or larger lighter weight rocket kit is ideal for a L2 certification rocket in Eastern MA, again to keep the altitude down to a reasonable level.

On the subject of motors...when you buy a reload kit does it come with a motor or is the motor separate from the reload kit?

thanks,

Unless it's a single use motor you buy the case and fuel seperate. It's pretty rare to find a single use motor, I consider myself lucky to have once burned an I132-14 Aerotech motor, 15 years ago
