[RocketsNW] Mike's M7500/Jack's ETV Brothers flight report

[Steve Cutonilli]

Jack - gives us more info on your rocket.

What altimeter(s) were you using?  What was the pad weight?  

If an altimeter recording was captured - came you post a screen-shot of
the flight?

Congratulations to Mike for both of his motors and the Mr. Scary flight.
It was an honor for my rocket, the Extreme Test Vehicle, to test fly the
M7500 that Mike created.  Even after the 'whipped' pad and the awesome
thrust of the motor, the ETV held together under the incredible stress
of the launch to achieve an altitude of 16,163 feet at over Mach 2.  

Not bad for a four inch diameter bird with aluminum fins on a three inch
motor.

My thanks go to Mike for building this incredible motor and to David
Holloway, my good friend and rocket buddy who always goes above and
beyond to help me with recovery and my eight year old daughter, Joanna,
for being such a trooper and always wanting to look after her poor
daddy.  David, Joanna, and I trekked to the other side of the ridge,
through the town of Brothers to a point along RT. 20 a mile east of
town, back .5 miles toward the town, over and under several barb wire
fences to a field back toward the ridge about .4 miles away from the
town before we found the ETV waiting patiently after that breakneck
flight without a scratch on her.  Then we carried the rocket back to the
east edge of town before we proceeded .5 miles along the road back to
our Highlander SUV, hoping that none of the locals would call the
sheriff and alert him about "them two fellars and the little missy
carrying the pieces of that there UFO back to their yuppie-mobile."

As for the weather, thank God that it was only 80-82 degrees during our
rocket safari, making for a comfortable, though long search for the
rocket.

Both of my research flights were nominal with full recovery, aside from

maxxing out the pico alt at 269.5g's in Mr. Scary, and the M motor
whipping the   
pad out from under it making for a long recovery. 

Rick posted a neat picture of the M motor with lots of well defined blue

mach diamonds. 

The video does not show much more than a blur of either flight, but I
can   
tell from the video that the burn time on the M was longer than expected
by   
about .5 second, so I'll probably have to downgrade the thrust to a
wimpy M7500   
or so. 

The weather was near perfect.  No clouds, almost no wind to speak of
either 
Friday or Saturday.
