What is/was the biggest professionally manufactured, commonly retailed BP engine? I actually flew an FSI Mach One Dart, which used the F-100 booster motor (with fins glued to the casing as per the directions), I forget the upper stage motor. I don't know if it went supersonic, but it was a very calm day and it was climbing very fast when I lost it - I found the rocket with it's 6 foot streamer 2 days later on the way to work, about 2 miles away. Never found the F-100 casing with fins.. I hear tell Centuri had some F's at one time. Is that it for BP or were there bigger ones? Neutrodyne
Big BP motors.....

RocketFlite used to make some awesome large BP motors, in sizes F, G, and H.
Isn't there an H330 or so in the motor data files for WRASP?

"Gravity assisted pieces of the rocket raining from the sky should be avoided. It is also financially undesirable."
John, I believe FSI also produced a G BP motor. I have an old catalog('87?) & I believe it is listed in it. DR
WRONG!
FSI had a G range "Thunderbolt" motor that was APCP.
Not commonly retailed. Rocketflite.
Commonly retailed FSI and Mini-Max.
FSI was by far the resounding long-term success story.
D20-10 I think.
No way.
It was composite.
The biggest BP motor I've seen is the cloud-seeding rocket motor produced by Ruggieri in France. It's a light J (can't find the specs at the moment) and somewhere around 2-1/2" diameter and around 20" long.
Ray, It's my understanding that they hope to produce motors in the future. I believe they are moving to a facility where this would be possible. DR
Please tell us more about that.

wow that would be cool.. back in Febraury a member of our club launched a RocketFlite H BP motor and it literally ROARED off the pad.....very impressive

Another project was build a balsa glider from scratch using your own design. Well, I designed and built a glider with slightly swept back wings, about 3 foot wingspan, and the first flight went all the way across the field and landed gently on the grass. The aeronautic instructors jaw dropped and he said "Perfect flight, I want that plane". I received an hour of flight training in a cessna 150 for being the top student in class. This was when I was a 10th grader in high school. P.S. now that I think of it, I don't think the enerjet was a BP motor, that was almost 30 years ago. Dave B.
centuri bought coaster corp and their e and f BLACK POWDER motors and renamed them mini-max.
centuri also bought rocket development corp. they redesigned and relabeled the rdc enerjet e and f POLYURETHANE composite motors.
fwiw ... i have original documentation and samples of these motors.
Yup, I have one sitting here. This bugger is HEAVY!
You guys are breaking our tradition! Stop citing such accurate and historic information or some lurker may think that some people here are serious about rocketry! :-)>
Post images and scans.
Tarnation Shockie !
Flying an un-certified motor at a club launch !
Will the humanity ever end ?
Hey at least it was not the ULTIMATE fopah, a USR motor.

Done deal.

gene: sorry about that....

Centuri didn't redesign anything when they bought RDC. R&D on the Enerjet motors with built-in delay trains (vs. the original Enerjet
8 with its external chunk of Thermalite) was already underway at the time RDC sold out to Centuri.The Enerjet subsidiary was under constant pressure to cut the cost of the E&F motors to improve Centuri's profit margin - often at the expense of reliability...
