I have created a web page with the preliminary specifications of the new
MultiClass Acoustic Tachometer. It can be found at

Some of the specifications are:
High resolution reciprocal counter, 7 digits background resolution. 4 or
5 digits readout, user selectable. A conventional counter has a
resolution of 1% (3 digits) and a precision of 2% at 20.000 RPM. This is
barely enough for proper motor adjustment.

Committed distance range is 0.5 to 15m (2-45 feet). Stretch goal is 400m
(1200 feet) to enable evaluation of the motor/prop performance during

1000-60.000RPM. Adjustable measurement window.

Advanced filter for optimum precision.

RS232 port for export of data to EXCEL and other PC based software.

Support for 2 and 4-stroke engines.

Support for up to 8 cylinders

Best regards,


Dutch Team

Hi Roger,

In addition to the other countries who have published their national
teams for the 2001 USA World Championships, these are the guys who have
qualified for the (not yet officially confirmed) Dutch team! Mentioned
are the first four in each class, together with the points they gathered
over the season in both national and FAI World Cup contests.

1. Maarten van Dijk, 221 points
2. Ivo Kreetz, 156 points
3. Antoon van Eldik, 134 points
4. (reserve) Jurgen Maassen, 54 points

1. Pim Ruyter, 228 points
2. Anselmo Zeri, 135 points
3. Henk van Hoorn, 115 points
4. (reserve) Thedo Andre, 95 points

no competitors qualified

Kind regards,

Ivo Kreetz

Flexible Maxes
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.

My understanding about the flexible max system the CAIM approved for 2002
is as follows. The time of each flight is divided between the "regular"
time which in the example cited by Jim Bradley are six flights of 3 minute
maxes and a last flight with a 2:30 max. The "residual" time between the 3
minutes and the extended maxes are effectively mini flyoffs.

We therefore have three cases: The flyers who max out all the extended
rounds continue to a convention flyoff at the end of the contest; Second,
the fliers who have maxed out all the regular maxes, and have dropped some
residual time; Finally, fliers who drop below any of the regular maxes
during the contest. In this format, once flier is "unclean" (dropping
below a regular max) he/she should continue to fly to the standard max. It
is not clear why the excess time of an "unclean" flier should still matter
on fairness grounds.

The intent of the proposal was to curtail the size of flyoff in large
contests. It clearly favors high performing models, that have have better
chances of surviving marginal air. Furthermore, instead of collapsing a
contest into a single flyoff, contestants will have to pass higher bars to
get there. The negative side of the proposal is the need to reprogram
mechanical or electronic times each round, increasing the chances of early
or late DTs.

Most fields, however, are too small for this flexible format anyway. In
larger fields, flexible maxes will make contests more interesting and
reward consistency and performance. Is that so bad?


Mill for sale
Author : This email address is being protected from spambots. You need JavaScript enabled to view it.

Hello Roger, I don't know if this is okay  or not okay but I have
for sale a brand new Grizzly#8689 mini milling machine that has a range
of 4" x  9.5"  on the y and x axis. It comes with its on bench
stand  and tooling such as a drill chuck, 3- , #3 morse taper ground
1/2", 3/8", and 3/16" end mill holders plus the standard package that comes
with the machine, which also includes an industrial version of 1/2" and
3/8" end mill holders as well. Also there is a brand new precision tool
makers vise
that allows a broader range of usage in setups and larger range in
chucking or clamping. Included are all the wrenches  and chuck key.
The spindle geared head stock range is 0 to 2500 rpm and the horse power
is 4/5 hp. A nice feature on the spindle is that it can be deployed as
a ram movement like a drill press or by shifting the shaft, it can be adjusted,

so that the .001 range micrometer can be dialed in for precision work such
as milling or  the use of a boring head application.
The quality and design of this small bench mill is exactly what I wanted
and got. Its a very nice mill for a hobbits and will make a craftsman happy
and extend his or her range in modeling far beyond our dear old dremel

The shipping weight is around 200lbs created in a wooden create and
can be delivered by any good freight line of the buyers choosing or I'll
take care of it .Of course the buyer pays for the shipping. The selling
price can be found out by an email inguiry at This email address is being protected from spambots. You need JavaScript enabled to view it. or call
303-364-4718 ask for Clay Parker.
Need to sell as soon as possible.

Regards, Clay Parker

Changing the Max

I think that the rule about the CD raising and lowering the maxes is far too
simple, there may actually be someone who understands it. I can just imagine
how willing the CD of a contest would be to use that rule and then have to
explain jim's scenario to the contestants at trophy time. If I were the CD, I
would be very reluctant to even think about it.
