I'm considering returning to the hobby of Model Rocketry after a 42 yr hiatus.
The last time I flew model rockets I was in the 7th grade and I sure have missed it. My question is: is there a rocket/rockets that can be used to get me reintroduced to the hobby with pontenial for a L1 certification?? Or would you keep the learning stages seperate?? i.e. A rocket for mid-power, a rocket for L1 cert, one for L2 cert...ect, ect. I'm not looking to break any altitude records, just a slow climbing, crowd pleasing fun rocket(s). Any input would be most appricated. See you at the luanch pad.

Welcome back!!!
I guess I'm a little late on this thread, but I throw my :2: in anyway.
I think I'm a little like you, flew rockets in 7th, 8th, and 9th grades and then didn't fly for over 30 years until my son brought an Estes rocket home from school and wanted to fly it again. That got me started again.
I started out with Estes we flew in the school yard. Then I found out they make big toys for big boys. I got a couple of 29mm HPR type rockets, but flew them on F and G motors for several years. In my case, I wanted to learn about HPR so I scratch built a dual deploy 38mm MMT rocket for my L1 cert. Scratch built a 54mm MMT rocket for my L2 cert. I finally broke down and got a kit for the L3.
That's my background, and my advice coming from there, build a different rocket for each level. Build a rocket appropriate for each level!
The Estes Pro series were designed for MPR motors. They fly great on those motors and you can learn a lot building the Aerotech Hobbyline 24/40 and 29/40-120 motors. If you do use one for your L1 cert, you will have to do it on a calm day because it will get a lot of altitude on an H motor. Then after you cert, you still won't have a L1 rocket you can fly L1 motors in unless it is a very calm day.
My advice for an L1 rocket is something with a 38mm MMT and in the 4 to 6 lb range so you can fly the whole range of H & I motors in it. What you won't realize when you cert is the difference in power the L1 motors have over the MPR. That is something you only get a good feel for after you have flown some. You will learn to fly your field with the larger motors. That's something that comes with experience after you certify, if you have a rocket that can fly the full range of L1 motors. You will also find that the higher level you fly, the higher the altitudes are and the more important "flying the field and conditions" becomes.
When you are ready to move up to L2, I would recommend a rocket with a 54mm MMT, dual deployment, and in the 6 to 10 lb range. That will let you fly baby J to baby L motors. What you will find is the difference in power in the L2 range is even more then L1. A rocket that get 2000 ft on a baby J will push 9000 ft on a baby L. If you start out with a 75mm MMT so you can use the full range of L2 motors and get 2,000 on a baby J, you will be pushing 12,000 on a full L motor. Again, you learn to fly the field and conditions.
If you decide to go for L3, you should have plenty of experience and any advice at this point would be useless. Actually, that sort of applies to L2 also.
The best advice, have fun!
