Bertha vs Baby Bertha
Can someone please answer a question for me?
Besides the length, are there any other differences between the Baby Bertha and the regular, full size Bertha? I know they are both BT-60 based and both have 18mm motor mounts. The fins appear to be the same shape but are they the same size? Thanks Les |
Yes and Yes!
So there! :rolleyes: |
I built the Baby Bertha years ago. I lost it in a launch. I painted it baby blue and called it "Baby Blue Bertha" It was just a shorter BB.

I thought the Baby Bertha's fins were slightly smaller. If not, you are paying over $13 more basically the same kit, but with a longer body tube!
Seems like $24.99 for the Big Bertha is just a bit high considering the simplicity, and especially compared to other bigger and/or more detailed kits. |
The Baby's fins are a slightly different shape and are made from 3/32 inch thick balsa vs. the regular Bertha's 1/8 inch thick fin stock.
I'll try to take a comparison picture tomorrow and post.... But yes this is another place where Estes' current retail prices seem kind of silly. |
Actually, some time back one of the members here posted an extensive comparison of the Bertha/Ranger family fins over the years. They've actually changed a couple of times. Given that, I think swapping an 18" piece of BT60 and calling it a (full) Bertha is quite acceptable (and a darn good deal to boot).
