The third MASA meeting of 2013 was held at
the Hennepin County Brookdale Library on March 7.
President Neal Higgins gave a summary of
NARCON; NAR membership is at an all time high, and NAR finances
are in excellent shape.
Neal Higgins also gave reports on recent
outreach activities; in February, Chris Feld gave a presentation
on rocketry to Boy Scout Troop 570 in Plymouth. Chris Feld, Neal
Higgins, and Buzz McDermott assisted with the troop's build
session. The troop held a launch on Half Moon Lake in Plymouth,
for which MASA provided equipment. The launch was attended by
Neal Higgins and Chris Feld.
Neal Higgins also informed the membership
that a Cub Scout group had contacted him and was interested in
having us do an outreach event for them. He mentioned that this
was a group of 4-5, and that they would fly their models at a
regular club launch. Date, time, and location were to be

The meeting concluded with a
build session led by Rick Vatsaas. Nine members built rockets of
Rick Vatsaas' design, which incorporates a cardboard coffee cup,
plastic lid, and a plastic wine glass.
After the meeting, Rick dubbed
this rocket design the "Vente Vini Vici".
The plan is to drag race these
rockets at the June MASA launch.

Here are the details that Rick
sent out in advance of the meeting:
The plan for next Thursday’s meeting is to build a Rick
Vatsaas style disposable cup rocket (oh, that so needs a better
name), The cost per kit is going to be $3.00, $1.00 if you
want to add an engine clip instead of friction fit motor.
The finished rocket is about the same size as an Estes Fatboy.,
so $3-$4 bucks is a pretty good deal.
