This is only a quick update mostly for
completeness. With dad away overseas this week we
brought along one of Paul's friends to come
and help us prepare and launch rockets. It
was his first time out to the range so we
launched both water and pyro rockets.
We launched 3 different types of water
rockets; a medium one with foam, a long one
with just water, and a small one with a
large nozzle. This covered the acceleration
range of water rockets nicely. All the
rockets flew successfully.
The day before launch John and I put together
the rocket Paul won in the
rocket
competition a few months ago. There was no
point in just letting it sit in the box. The
hi-flier is a kit made by Estes.
We launched the high-flier, now renamed
by John to "Buzzard" on the biggest motor we
could fit in which was a C6-5. The altitude
on the packet says around 1600' on this
motor. I figured we had a 50-50 chance
of getting it back. The rocket flew well and
we could see the smoke trail all the way to apogee and
see the ejection charge go. It was very
difficult to see at that range but we were
able to track it as it was coming down.
Thankfully there were a few clouds in the
sky which allowed you to focus your eyes at that
range. The rocket drifted further and
further away and the last few hundred feet I
could only see the faint flashes of light as
the rocket tumbled reflecting the sun off
its fins. The
rocket landed beyond the tree line. The 4 of
us went looking for it in the tall
grass but walked right up to it!
We also launched "Waterless" on the other
F20-7W we had saved from the last launch and again it flew nice. This
time it landed closer and was easy to
retrieve. Paul's "Flygon" flew great on the
D12 but came down fast under streamer and
hit the ground buckling the lowest portion
of the BT. This will need to be fixed before
next launch. We may also replace the
streamer with a small parachute.
No video this week as there really wasn't
anything special about these flights.
