FSI Extravaganza at LDRS 40

[Arnie]

Thought I'd share some more follow up. I flew thirteen F100's at LDRS. Out of those, eleven worked nominally and two split casings. Chuck and I did two Mach 1/Dart attempts: the first worked great but the second failed to light the sustainer. I got the sustainer back intact and will whip up another F100 booster and try again another day. I'd really love to get all three Dart stacks up in the air and compare altimeter data from all three. Based on the results from the first good two stage flight, I think it's safe to surmise that Mach 1 is possible under optimal conditions. No sonic boom was reported, however.

My F100/F7 two stager flew Friday morning. The F100-0 booster worked fine but the F7 didn't light. I never got the chance to attempt the three stager.

Here are some mediocre pics and video of my Enerjet 2650 clone. F100-8's worked great and delay was right on.

Will they be allowed?

Also, I wrapped some fiberglass motor tubes/airframes for FSI minimum diameter projects. Let me know if you want any. I won't have anything ready for this weekend, but I'm still down to do the aforementioned drag race at April Rocstock.

Will they be allowed?

Yes, why wouldn't they? They all have the CSFM stamp. And thanks for the tubing offer but I'll have to pass. I've got way too much rocket crap as it is.

My bad, I forgot they did have the stamp. No reason they shouldn't be then. April Rocstock F100 drag race?

It's on like donkey kong!

BT55 three stage. F100-0's in both boosters. I haven't decided if I want to try an F100-10 or an F7-6 in the sustainer.

 

[DeeRoc29]

The three stage flew today on F100-0 to F00-0 to F100-10. All stages lit and flew nominally. Didn't go as straight as i would've hoped, but it still went high.

Awesome flights today! How high did the F7 go?

 

[DeeRoc29]

I also flew the lightest, tiniest rocket I could put together on an F7-6. Firefly recorded 3216' apogee. This was the straightest flight I've ever had with one of these!

 

[DeeRoc29]

Awesome flights today! How high did the F7 go?

3216. Much higher than I was anticipating! I was super happy with the F7 flight. Now I just need to get an F100 to boost an F7 and go that straight.

 

[DeeRoc29]

I attempted another Mach 1-Dart two stage flight at Rocstock this past weekend. Kaboom.

RIP to this one. I've got a few more F100-0's in my stash but only one more more sustainer D20-12 left. I'll put another Dart together and try one more time in 2025.
