Good luck! I upscaled my GBI (Great big Inductor) from 18 to 24, and the larger engines damged the tubes much faster (blowout after 2 flights, as opposed to veey toadty after 5)

Thanks Nytrunner! However mine isn't induction stabilization...it's more ducted air stabilization. :)

I've upscaled some of the "normal-side up" rockets to 18mm and successfully launched them, but they're not very efficient (very draggy of course) and so altitude wasn't very high. Still I thought they were very cool and fun.

Hi everyone, I'm back! Again! :p

Just an update that I had this on back burner but plan to revisit it again this year.

Before I stopped in 2016, I was actually considering a patent, so I didn't share out too much info, but I got as far as creating 13mm kits for some of my rocketry friends to try and test. Sorry, not going to create any of them anytime soon, but maybe in the future (which could be near future the way things are going for me at work *sigh*). Also I'd have to find the instructions on some old laptop somewhere.

Coolest thing was that these kits fit into a small USPS box!

Also I don't recall if I mentioned it, but I did start some 18mm mmt upscales before my hiatus. I did have success with these and they were a lot of fun and so cool that you can carry them in a small box and convert them! Here I have a RAIStone and RAISJet version, complete with exhaust nozzle. :)

So I still plan more designs, builds and testing, but on a more relaxed and enjoyable pace this time!

BTW - I did test the Apollo capsule again with the newly available D16-4 and it boosted straight to about 100' and then went horizontal, so I think I'm close and have some ideas...
