I'm assuming that I should just be building stuff out for the 100 pin
package (2368), but there are a few things I could set up generally... This
is to say that in most areas, with basically no additional work, I could
allow the code to extend to the full features of the 2378 (144pin) without
Well that's just it; I was at the road-station two miles away and I
never heard the engine sound. All I heard were two cracks about ?15?
seconds after launch. Would I have heard a chuff sound if I never heard
the engine sound? Just curious.

That was the motor chuffing, we
Given your experience, the youth of TM's software and
hardware, and the prediction of supersonic flight by the
simulator, I'm willing to believe we may well have been
supersonic or at least transsonic on Saturday. However, it
will be really hard to tell, I think. We might be able to
cal some
I guess my thought is that sound, at least as heard from our respective
locations, isn't a good indicator. I had a good feel for the sound delay
from the kids' rockets, and I heard the engine sound and then the two
booms. I think I have a pretty good feel for when in flight the sound
occured, as
Hi all,
One slightly dispassionate observer out here thinks that transonic is
feasible for this one, but probably not supersonic.
mach 1 is 335 m/s measured at sea level at 59 deg. F. The speed goes
down as as elevation, altitude, humidity and air temperatures increase.

Keep in mind that all the instruments we used for those
velocity measurements have some interesting limitations at
this point. The pressure altimeter is known not to work so
well in the transsonic region. The z-axis IMU hasn't yet
been calibrated terribly effectively. The GPS is quite
inaccurate
