What recommendations to folks have for a mid-power rocket that could also be used as a Level 1 certification rocket? Any pros/cons of your suggested model would be appreciated.
Since NSL is near me this year, I might do it just to have 'done' it, but I do mostly mid-power these days.
I modified an aerotech barracuda to have a longer 29mm motor mount with no thurst ring, and I routinely fly it on anything from an F24 to an H180. I also have a PML Black Brant VB that I fly on everything from an F40 to an I211. Overall, I think you have lots of choices for rockets that would fly on E-H or F-I motors.
Here are some of my personal opinions of the pros and cons:
Aerotech - base rocket is often cheaper. Easy to modify for longer 29mm motors. Mirage, Sumo and G Force also easy to modify for 38mm motor mount. Cardboard is a bit thinner, though. I've had lots of problems with the plastic fins bending. I like the baffle which eliminates the need for wadding/barf/chute protectors.
PML - basically a waterproof rocket, which is good if you launch in a field with a lot of puddles and watering holes. Pistons are nice because they eliminate the need for wadding/barf/chute protectors. Some people have trouble with the PML pistons, but I find that if you simply follow the directions and sand the piston to slide freely at the lowest temperature at which you launch, it works reliably. I have had some problems with the fiberglass fins getting a permanent bend in them after a hard landing.
LOC - nice kits, a little bit sturdier tubes and fins than Aerotech (but also a little heavier).
This very topic has been discussed in great detail by the members of our club, the Austin Area Rocketry Group. I summed up the findings in a post to RMR some years ago:
The AARG Quick 'n Easy 10 Step Cert Process!
1) Order an Aerotech "Sumo" kit and H128W motor. Ask about alternate sources for the motor when told by vendor that it is "temporarily unavailable." Ignite week-long flame war covering topics as diverse as "who's fault the fire really was," American-Canadian foreign relations, and scheduling for DC district federal court judges.
2) Open the kit box. Remove engine hook and directions. Throw directions away. Save engine hook for later epoxy mixing.
3) Endlessly debate the merits of CA vs. epoxy adhesives, preferably with folks who have never used one or the other. Purchase selected adhesive from obscure boating store when discussion thread dies out.
4) Open container(s) of CA or epoxy. Throw entire bottle(s) into "Sumo" box. Close box.
5) Shake "Sumo" box aggressively in order to spread glue around. Continue shaking until parts quit rattling, or box becomes too hot to hold due to glue curing.
6) Choose a color of spray paint that you wish to finish your rocket with. Throw can into "Sumo" box.
7) Place "Sumo" box in your backyard. Shoot repeatedly with shotgun until spray paint can inside explodes. (Remember that several light, even shots are preferable to one intense barrage of gunfire!)
8) Remove finished rocket from box. Remove buckshot from surface of rocket before paint dries.
9) Steal appropriate motor. Fly rocket. Get certification.
10) Tell endless stories at future launches that begin with "when I got MY certification..."
(Optional bonus step)
11) Repeat for Level 2 & 3
Hope this helps, or at least provides a chuckle, James

Hi David: I used an Art Applewhite flying saucer for cert 1. His "cert 1" URL is at

and he offers a $20 rebate if you cert with one of his kits.
I then built a BSD Horizon 4"

with dual deployment to gain experience in a more traditional high power rocket. I've since used that kit for cert 2 and for playing with the Rouse-Tech CO2 ejection system.

Well well, finally someone asks so I can post the list once again. Most of these people have moved on from RMR, but here it is:
Folks, please keep in mind this is supposed to be the list of recommended rocket/motor combinations for L1 certification...not the list of who certed with what. If you would not recommend what you used for certification to a newbie please don't submit it for the list as they might not know, for example, that a single deployment VB Extreme 38 on an I284 is not really a good cert choice.
