I just got my falcon 9, it’s pricy, but I personally think it’s worth it
I think so too.But what’s with the chuffing? I’m thinking some rockets wasted significant powder bouncing on pad before finally clawing skyward?
Just don’t smoke for 24 hours prior to launch and don‘t drink within 10 feet of the pad.I think so too.
The D22-4W in the Bomarc was a new QJet 24 mm white lightning motor.
Bought it just a few months ago.
So couldn't be oxidation or swelling.
I have had terrible luck with QJets.
Nozzle erosion, casing burn thrus, and now severe chuffing.
Almost drives one to drink.
And abstain from se,,,,,,,,,,,,,,Just don’t smoke for 24 hours prior to launch and don‘t drink within 10 feet of the pad.
Jake has a bunch of old motors, some have the old initiators with the single copper strip. I threw out the ones where the holes closed up from swelling. My plan was that the DBCP was going to go straight up so had time for the 10s delay to fire but arced over instead, maybe due to old propellent.I don’t use that many low power composites (yet!). Seems like a higher percentage of “chuffing” than usual on your last launch.likely why the Bomarc (fortuitously) had an ultrashort flight, but also may be why Patriot deployed at low altitude (not a JLCR malfunction but a failure to reach adequate altitude and velocity at thrust burn out, so EJECTION was barely in time . In fact, I am wondering if the JLCR didn’t function EXTRAORDINARILY well, probably released the bands BEFORE the ejection charge fired, recognizing the rocked had ALREADY exceeded and the descended below programmed altitude.

I think the chute slipped out from the rubber band at ejection. but the servo didn't release until the programmed altitude. Consistent with what I see on the video.I'm still not sure why the JLCR opened at apogee in the Bounty Hunter. The rubber band seems fine. I'll replace the insert just in case. The rocket landed just before the construction yard so worked out.
No reason to toss them unless the grain is not in the liner. If it is in the liner and closed, by hand, use a drill bit to open it up. If the liner is too tight, because of the swelling of the grain, peel a little paper off the liner.Jake has a bunch of old motors, some have the old initiators with the single copper strip.

I have had that happen with the JLCR and with Archetype Cable Cutters. Not often, but it happens.I think the chute slipped out from the rubber band at ejection. but the servo didn't release until the programmed altitude. Consistent with what I see on the video.
Might have a slight case of Peyronie's.

Nah, it did remove the weeds though so I did them a favor.Did the F motor mess the grass up and put a hole in the ground?
Yes, that's where I'm buying them. Some are able to find them in clearance aisle for $15 at Hobby Lobby.Ron: is $30 the normal price for an Estes altimeter? I found one new on Ebay
Scratch built mine from the plans in the Apogee newsletter.I just got my falcon 9, it’s pricy, but I personally think it’s worth it
If I had my own 3D printer the costs would be much less.
