Easy build, impressive results

By: Nakota1294

Balsa fin rocket with unique proportions that look impressive on the shelf or on the launch-pad. Easy build that would make a good introduction to model rocketry or taking the step from ready to fly or almost ready to fly. Rocket is well balanced and flies straight however the recommended motors do not deploy the chute at apogee or near apogee which makes for some pretty tense recoveries with the chute deploying at about 50-75 feet and filling just in time to catch the rocket before it touches down. Makes for a short walk to recover the rocket, so I guess it's a plus ;)

Tough little bird

By: mhrdeadhead

Just as stable as the Big Bertha, and just as easy to build. Stable flight, soft recovery within feet of the launch pad. My first flight had the nose separate from the body. The body did a header into the turf (no damage) and the cone landed 100 yards downwind. There's a lot of force from the C engine ejection charge and it's confined to a short body. Double check your knot and add a dab of glue to the knot...

Baby Bertha better than Big Bertha

By: danomite45

I built a Big Bertha many years ago, and recently discovered the Baby Bertha. When I opened the Baby Bertha kit I was a little let down. The balsa sheet looked like it was joined from two different pieces of balsa, half the sheet was a light color, the other half was darker, with a ridge in the middle. A little sanding took care of it just fine, and the fins appeared stronger at the joint. Also, I really prefer waterslide decals as opposed to peel and stick. In the end, it didn't matter much because I didn't use the decals anyhow. I do believe I like the Baby Bertha better than her big sister.
