CMASS, Amesbury launch coming Saturday, 11/7/15.
Wrapping up with a night launch.
Let the slaughter of D11-P engines commence...
Oooooo night launch? I was already going, now I'm staying for the night part too. What's the impulse limit at night?

Built the 3 motor tube assembly specified for the Tres kit....
But the motor tubes looked lonely....And the build was getting heavier, with an expected flight weight of about 20oz...
So I added three more motor tubes...:dark:
The night launches (both after the 7th and 21st of November dates) are limited to model rocket specs and an altitude of 1000 ft. Your rocket must have lights to be allowed to launch (glow sticks are not visible at any significant distance) for appearance during the flight and recovery on the ground. If you haven't flown with us at night, it might be best to observe this first one and prepare for the second one.
Does that make it a Seis?
Ok, I was there for the LDRS night launch which I believe flew under the same rules. But if I can figure out how to stick some LED strips and a battery pack on my SPAD by the 21st, you can expect to see that.
Yes it does.
Seis (6 in French) is the name I am leaning towards.
1) Some of the LDRS night flights were well prepped and well lighted.
2) Others flew like they were built and prepped in the dark....with poor lighting and ballistic recoveries....
I'm pretty sure what Ken is getting at is that we want 1) and not 2)
Um, tres and seis are Spanish...I figured by now the Seis would have grown to the Nueve.

The stabilization mount you rigged up seems to work very well. Videos aren't shaky anymore.
Awesome!!! Boris -- are you using CFs by themselves in the G64Ws or do you paint the top of the grain with pyrogen as well? I know you had been doing that. Thanks!
Yes, definitely. Anytime clustering AT G64 and similar motors, I put some Rocketflite ML pyrogen at the top of the propellant slot.
Usually gets these AP motors up to pressure in the same 0.1-0.2 seconds as the BP motors.
Most smaller CTI motors do not need this due to the BP plug many come with to serve the same instant-on purpose.
Yes, handheld video stability was much improved. Also allowed me to aim cameras more accurately too.
The shoulder mount handled well and was not cumbersome to use.
Will try to position pad camera closer, frame handheld video a little more tightly on the action going forward.
Not long ago at a launch, I was admiring the lovely Rocketry Warehouse Adventurer 3 kit among AMW's many rocketry goodies.
Then in an act of rocketry magic, it traveled home with me.

It's one of those cool rockets that looks fast even when standing still.
Like most larger kits, the flier supplies recovery, motor retention and other hardware.
With very minimal sanding of the fin slots, all parts fit together perfectly.
pic 2: Altimeter bay covers have a nice double-cut perimeter for what should be a good seal.
Fins come with sharp, clean bevels.

It's very close to a 2x upscale of my Carbon Weasel, which uses fins and NC from the LOC Weasel.
Prepped airframe weights (+recovery -motor) also scale proportionately.
CW 1.0lb / A3 about 8lbs
