Agreed . . . When it comes to BP motors, especially larger ones, Estes looks like the "only game in town" to, eventually, produce Core-Burner motors. Dave F. |

Going slightly off the Coaster thread, but staying on the Black Powder Nozzle thread, the Rocketflite H220 is by far my all time favorite black powder motor. And the F50 is right behind. Coaster motor shown for comparison.

What was the "G" version of those Rocketflite motors ?
I had one maybe 16 years ago that I flew in a Semroc 1/2 scale SLS Arcas. My backyard was really nice to fly out of. It bordered a 500+acre Soybean farm that I had permission to recover rockets in. I could easily fly under FAA limit H-power out of. I just had to watch for Aircraft traffic as it was within FNT approach control. Commercial and Cargo aircraft flew directly over my back yard.

Re Rocketflite 'G' motors: I believe the H220 was re-labeled as a G at some point, but they also produced another G - Steve Naquin or StefanJ can probably help out here.

I've got some spent Rocketflite F, G, and H Silverstreak casings at the house. I'll look and post the designation tonight if nobody has chimed in.

Yes, there was a G160.
If Memory Serves, the first Rocketflite motor was a paper-cased F101. This was reclassified as a F55. They were longer than the old FSI F100. F101 were dodgy. I remember a few spectactular catos. Lemme tell ya, a catoing "silver streak" F55 was VERY efficient at starting grass fires. One of my friends made a video, now lost to time . . . The later motors had aluminum cases with a thin brown paper spiral wrap. For a while they were pretty reliable. Shortly before they became unavailable, quality plummeted. But MAN, when they worked, they were awesome. We had plenty of cheap Vulcan and Aerotech motors, but that black powder thrill kept us buying Rocketflite motors. I once staged a F55-0 to a F55-7SS, in an old North Coast Quasar II. It was dusk. Staging took place only 100' or so up. The shower of sparks against the darkening sky was splendid indeed.

I thought it was a G70, but may have been a G160.
All I know for sure is it was a Rocketflite 29mm motor.

My favorite commercial mid and high power motors. We did much larger EX stuff, but these were fun. The F50 was dead reliable for me. I didn't do enough with the G and H to judge reliability, but I saw quite a few H's burn from both ends in air started clusters back in the day.

I never had a failure on an F50. I bought a bunch of F50 Silver Streaks from Ross Dunton of Magnum, at LDRS 13 in Argonia in 1994. He had a huge footlocker full of them. Flew most of them in Argonia, but brought a few home. I bought a G160 and H220, too, but never flew them. I gave them to a friend about 20 years ago. He probably still has them. I should get them back, or demand he try them. Would be fun to watch.
