Good call. Just toggled it off. Didn't realize autocorrect and predictive were two seperate functions.Hey Kit, you can turn off the auto-correct on your IPAD. I got sick of it changing words on me and nixed it.
I made and tested some sugar motors. I think I have the nozzles just about right

That's a spent 18mm in back. I'm prototyping on a small scale until I get it figured out.
Here's a couple of my next size, in the front row...

Yes, that's kitty litter. I ran it through a pepper grinder till it was dust/powder, then rammed it. Hard as a rock!
I appreciate someone who polishes their cat litter. A great deal of respect for what I assume is your pleasured feline.
Received decals from Mark over at Sticker Shock and completed my German A4b. I may add some nose art later.

What motor is that? beautiful skid by the way...
Did ground tests for BP charges on my RW Blue Iguana. Can't believe how far off my BP estimates were. Good thing I ground tested!
It flies tomorrow for the first time at our club field in Vermont.

How much Bp did you use? Also any shear pins?
Nice to see some Vermont rocketry happening.
It's too bad there is not a club closer to central Vermont, Barre, Montpelier area.
Calculated 0.7gr of BP for apogee test that you see here. All I heard was a "TICK". Tried 1 gram... tiny "POP" but no movement. Tried 1.25 grams and got a nice deployment. Yes, two 2-56 nylon shear pins on sustainer and another two on nose cone. For Main I calculated 0.38 grams and initially tried 1/2 gram.... NADA. Tried .75 gram......"TICK". Tried 1 Gram and got a decent deployment but not full extension. Frankly I was afraid to use more for fear of blowing a hole in the thin wall glass payload tube.
I flew the Blue Iguana for the first time today using 1.25 gr. for Apogee and 1 gram for Main as tested. Nice apogee deployment but no shear pin breakage on the nose, so no main chute. Good thing I used an 18" drogue at apogee! Sustainer landed more or less flat, nose cone with payload tube attached stuck in the frozen ground and then bounced out. THUNK! Sheared the thin wall nosecone clear off it's coupler but no other damage not even a scratch. It was only 30 degrees today. Wonder if the shear pins got cold-hardened. Next Time I use 1.25 grams and maybe only 1 shear pin. Again I can not believe how much powder is needed for a 2.6" diameter tube with an internal length of only 9.5" mostly filled with a chute and Kevlar.
