Brief:
Estes' re-release o' t' upscale Big Bertha.
Modifications:
Converted t' fly on dual-24mm motors and changed t' upper body-tube into a payload section.
Construction:
T' kit includes:
I built t' kit without directions, matey, but Estes has always done a great job with their directions. I wanted t' include a payload section, and while I was rummagin' around for an extra BT-80 section, me bucko, I came across some dual 24mm mounts for BT-80 tubing. Ya scallywag! Blimey! (And a big GRIN came over me face!) I figured with t' payload plus an altimeter, t' dual would be needed (Yeah right!)
I built t' kit usin' West Systems epoxy with Silica filler throughout, me bucko, really sloppin' it on near t' motor mounts. Well, me hearties, blow me down! Blimey! Since I was butt mountin' t' fins, I use t' old epoxy rivet trick. I punched holes with a pin along t' fin lines, ya bilge rat, me hearties, and squish t' fins on there, forcin' epoxy into t' holes and makin' "rivets". Aye aye! Blimey! Well, arrr, blow me down! Blimey! I have long since invested in an Estes fin holder, so t' alignment is quite good. Ya scallywag! Blimey! This kit is about as strong as an Estes kit can be. Well, blow me down! Blimey! Well, ya bilge rat, blow me down! Blimey! I expect it t' fly fine on dual E15's or E30's.
Finishing:
I have nay finished it yet, matey, but it will follow suit with all other Estes products.
Flight:
T' recommended motor is a D12-5. Avast! Blimey! I doubled up and use two D12-5's. Begad! Blimey! Avast, me hearties, me proud beauty! Blimey! Both ignited, and t' flight was nominal. Begad! Blimey! Both motors were successfully held in by t' dual hooks.
I then used two E11-5J's What a great flight! Nice and slow with a lot o' smoke! Chute protection is via wadding. Well, blow me down! No problems encountered there.
Recovery:
T' 'chute is now too small, and t' rocket comes down too fast. Blimey! But I like it that way, and t' rocket can handle it. Ya scallywag! Ya scallywag! I'd rather break a fin, matey, than loose t' whole rocket. Avast, me proud beauty! Arrr! But with t' epoxy construction, ya bilge rat, t' rocket be fine.
Summary:
I'm really glad Estes has re-released some o' t' old-timers. Ya scallywag! It's typical Estes, me hearties, matey, but great for nostalgia.

Intro: The Super Big Bertha is a re-release of the Classic Super Big bertha that Estes produced in 1989. This is an upscale of the venerable Big Bertha, one of the most popular Estes rockets. Rating: 4 ½ The Super Big Bertha comes in a cardboard box that helps to protect the components very well. None of the parts were missing, and all were in good condition. The materials are the ...
