I have found a few, easily available modules that have a maximum altitude above 100km (but still a velocity limit of around 500-600m/s). Those should allow for GNSS altitude verification above 100km. A friend of mine is planning on doing GNSS testing using a GNSS simulator to verify those...

I took the data point in the components analysis in OR. The mach number slide only goes up Mach 3 and I didn't bother going above using the sim.

Congrats on the nominal flight! Would you mind uploading your CAD design on GrabCad or other platforms so that other people can improve on the design? One interesting point: for Deja Vu and Gas Gas Gas, the stability margin estimated by OpenRocket was negative near burnout. So here's a...

This project is not dead by the way. I recently acquired an N5800

Hello, I recently flew an old Aerotech I500 at FAR. The flight went great. After the flight, we noticed that the burn time was much shorter than expected at around 0.3s and the flame was much longer than usual. The igniter used was 1.5g of Warp9 shavings in a glove tip. Could this be the reason...

Yes, all the fins were around the landing site, they held the up part just fine.

It was, indeed, my launch. I had two baguettes, one for the rocket and one for my launch. I ended up screwing up the first one so I had to use the second one...

Thank you @CoyoteNumber2 for driving out to meet for a pickup!

In the design, I set the minimum LE thickness to 1.2mm to account for that. Looking at the new part I received, the trailing edge is straight, but all the leading edges have an approximately ~0.5mm low spot around their center when putting a straight edge against them, but that could be from...

Thank you, I'm aware that a VK nosecone would give me more volume for electronics and recovery but I like the conical look more, mainly for ease of manufacturability and for making the coupling slightly easier. The angle of the cone was 6°. The nosecone getting locked onto the coupler is a...

So I've received the replacement fincan from 3DPnxt as the last one was completely butchered during the finishing process. I asked for no finish. Despite the fin thickness, it is only 190g. This will make for a not-so-good paperweight...

I have used those before, they are nice! you can also use lipo if you want more runtime.

Of course ahaha, I like to name my rockets after EuroBeats song: Gas Gas Gas, Running in the 90's (km) etc...

Thank you (: In CAD the fincan was 180g, and it was 190g as I received it. this is due to the leftover support material inside the fins. It could have been much lighter with thinner fins. I'll improve on the design to make it printable without internal support.

So I was initially planning on building a small 54 to 54 two stage rocket while in the US for my internationnal semester. After ordering the propellent and single use EMKs from RCS, and cutting the grains, I realized that I wouldn't have enough time to complete the project. So I was left with a...

I Flew a very simple rocket to 4.2km on an "experimental" 3G EMK moonburner (Slower white and Blue Thunder), +10s burn. The ground video was taken by @Brainstormz123: it just keeps on burning...

Aerotech M650 to 6.9km, this time with onboard video! Liftoff picture my Julian Rice, video by Joe Barnard. Here's the link to the raw onboard footage:
