FYI: Yes, the GoFundMe is still active. https://www.gofundme.com/stickershock23 Mark just got notification that the most recent donations are inbound to his account now. When I set this up, I gave Mark sole access to the funds. Aside from GoFundMe's fees, Mark and Marian get it all. I'm saddened...

I've got an old Toughbook that I use for field rocketry use. Checking altimeter data and such. I haven't done an SSD yet, but doing a clean install of XP made it WAY faster. 7 was stupid slow on it. I like the Toughbook because it was more or less the last laptop to have a real serial port on...

80/20 makes 1010 rail that should fit. Just replace all the Blacksky rail hardware with 80/20 stuff.

I use sewing elastic for my shock cords. Makes me much more comfortable in case of "bonus" delays in motors.

I've had excellent luck with epoxy putty. Lay it down, and a gloved finger dipped in alcohol smooths it right out. Works with JB weld and PC-7 epoxy as well.

Aw man... I totally want this. But realistically it'll be some time before I'm ready for making sugar motors. I'll pass and let someone who'll hopefully use it soon snag it.

I am a big fan of the Eggtimer wifi switches. Things work great, have continuity hookup if you want it, and draw remarkably little current for what they do. They draw about 85mA.

Been a while since I've been around, but looking good, Steven. If you decide to go with magnets, you can use a steel plate on the side that would be more difficult to dig a magnet out of. The other side could be neodymium. There are a number of places you can get assortments in one shot. I've...

I don't think it was actually a real rocket. Looks like Enerjet just liked the Nike look. https://www.rocketryforum.com/threads/enerjet-nike-ram-ke-1-gallery.58050/ https://plans.rocketshoppe.com/enerjet/enjKE-1/enjKE-1.htm

I have both a SkyRC iMax B6 and a Turnigy Accucell 6. I like both, but the SkyRC with the firmware version will charge lipos without a balance plug hooked up. As far as batteries, I really like using the 300mah 2s batteries for my Eggfinder Mini because of how small the battery is. I use...

On my 7.5" diameter stuff, the whole fin/mmt assembly is removable and the body tube is slotted to slide on to that. May give you some ideas: https://www.rocketryforum.com/showthread.php?142194-Level-3-build-for-LDRS-2018-(completed-vids-and-pics)

I always carry my Gerber Suspension multi-tool and a pocket screwdriver. And like others, I tape my igniter to the side of my rocket. The only other thing that I've ever wished I brought out to the pad was a heavy duty spring clamp to use as a standoff. In those cases, I just use a rock.

I can't argue that...

Depends on how pointy. I'd say any point rules out a DRM.

Sorry it took me so long. Here's the sim file and the raw computer data.

I'll get the sim file posted in the morning. Not sure if I have the altimeters here or if they're at the shop. Either way, I'll get the data eventually.

Adjusted for temperature and barometric pressure, with base drag cone added, the K2050 sim is about 15% off and the L1000 sim is off about 5%. Just because, I added 10% in thrust (in the form of a G127 in an outboard) and the K2050 sim gained 14% in altitude. I think this may be a case of...

Mark, I was sure the motor files were correct. Just wanted to head off those questions. Rich, there was not any discernible weathercocking with the K2050 flight. Here are the flights. https://www.youtube.com/watch?v=OEycnp8P0gQ https://www.youtube.com/watch?v=Xvh1HfR9N48

If the L1000 sim is right and the K2050 is off, that's about 22% variance. If the K2050 is right and I adjust the drag to match that sim, the L1000 is off about 23%. If I was within 10%, I'd just chock that up to margin of error. About 25% though... First time I've been that far off. Just for...

Running sims on my Uber Der Red Max (86" tall, 32.8 pounds, 7.5 inch diameter) the sim for a K2050ST runs about 920' up. Actual data was about 200' short. However, with a L1000W, the sim shows 2180' and actual data was within about 30 feet of that. Both flights were really straight up, so...
