Seems to be a popular scheme. This one is built with interchangable 1x18, 2x18, and 1x24mm motor mounts.
Mount Wilson Observatories in the background.
Thought I'd post this Youtube video of my unglamorous (I put on a white base coat, but never got around to putting on the rest of the paint) Ranger clone. It is made from a current Big Bertha, but instead of using a Balsa nose block for the payload section, I glued 1/2" foam core disks in the front and back of a CT-60 coupler tube. But the business end (cluster mount) was built using the Ranger's tissue and white glue filler.
The Ranger's flight is the second one in the video (the first is a saucer launched by the daughter of our club president who also shot the video). If I remember correctly, the Ranger was flown on three Quest A6-4 motors, hence the nice smoky launch. If you listen carefully, you can also hear the "pop-pop-pop" of the three ejection charges going off one right after the others.
I've said this before, but never posted pictures. I have two Big Berthas. The black one is my stock Big Bertha. The yellow one is Big Bertha Lite, which is skinnier by a few mm, weighs less, has thinner balsa, an aluminum launch lug, and an 18" black nylon 'chute. Both have been successfully flown on B6-4 motors.
I used Quest 40mm body tube, a Quest Elliptical nose cone, Estes standard "E" shock chord, 1/16" balsa, a piece of 1/8" aluminum, and an 18" nylon 'chute from Rocket Chutes. This thing gets up there with a B6-4 and has really dramatic recoveries.
Ahh, Quest parts. I thought that might be the case. 1/16 Balsa is pretty brave for those fins. Very cool rockets, nice work man.
Here are mine. The blue one is a more-or-less stock BB, while the red one is my infamous Double Barrel Baby Bertha, flying on 2x18mm engines.
Thanks for the kind words!The retro looks on those two are almost impossible to beat.
My Big Bertha and Mini Bertha
I think this thread needs to be broken up into threads specific to the Ranger, Big Bertha, Baby Bertha, Mini-Bertha, Super Big Bertha, etc.
