a good beginner rc boat kit. I have no gear now so any advice on
anything from "electric vs. gas" to "best style of radio" would
be more than helpful.

Or, if anyone has equipment to get rid of that will suit my
beginner needs (cheap), let me know.


Thanks!!,

No, the largest market is handheld tools. Powered tools needs high currents, but
not high as rc-models. 

I've seen some adverts about russian rechargable lithium-cells with very high
capacity compared with both Ni-Hy or Ni-Cd cells. It seems a lithium cell of
same voltage and weight has 10 Ah compared with 1.5-2A for Ni-Cd and maybe 
3Ah for Ni-Hy.

Subject: Second Race Observations
Organization: secure_comm
Date: Tue, 21 Jul 1992 11:41:11 GMT

Hello,

I recently participated in my second 1/10-scale, electric, off-road, 2WD
buggy race.  It was dissappointing that there were only three cars in the
"superstock" class, and I was the only one who stayed for the main, which
I declined to run.  I will henceforth participate in the "modified" class
to avoid this kind of problem.  Apparently, almost all of the modified
cars run 6 cells (a superstock class requirement) anyway.  

A mechanical breakdown list which may be of interest to CougarII owners
includes 1) yet another popping off of a lower ball cup on the front
shock from the ball on the A-arm and 2) a blown ESC fuse caused by the
seizing of the transmission.  Item #2 is of particular concern due to
the fact that a total disassembly of the transmission revealed only
minor dirt and no apparent cause for the transmission to seize.  More
frightening is the fact that at various times with the tranny either
in or out of the car, this symptom would re-appear and then disappear
after I rotate the shaft for a while.  I believe that the problem is
not inside the diff.  Experimentation to find the cause is difficult
due to the intermittent nature of the problem.  The cause for some
additional grittines that I found in the drivetrain turned out to be
that the 'L'-shaped pins that hold the rear hub carriers to the rear 
A-arm were turned such that htey scraped the inside of the wheel rim;
this was easily made right.  Any comments about problem #2 would receive
much consideration.

As far as Cougars go, I followed the Huttoesque advice of using the
Airtronics 94143 servo and have not been disappointed (although I
may not be an experienced enough racer to know that I should be
disappointed).  It mounts in place so nicely (a challenge on a CougarII
car), can easily be bolted in place, and gets all kinds of comments from those
who stop to look inside -- it has proven to be quite a conversation
piece, especially from other Cougar or ex-Cougar drivers.

I noticed that some of the drivers pulsed their triggers so that they applied
either no or full throttle, but they would do this rapidly to achieve some
intermediate speed.  Many drivers, including me, did not do this.  Are there
any thoughts on the matter?

Of course, I had my second Tamiya/Kyosho connector meltdown.  I went out and
bought some 'Sermos'/LiteSpeed/Anderson Electrics (whatever you wish to call
them) connectors.  For the sake of easily obtaining extras or replacements,
I considered only Dean's and Sermos'.  I think the Dean's look nicer when
carefully assembled and are certainly smaller.  The Sermos are infinitely
more easy to solder, however.

Good Day,
Bob Woodhouse

I heard lithium is even more dangerous than Cadmium. So dangerous that a whole
new kind of lithium battery was being developed in order to make mild overcharging
safe.

Perhaps this is why they are only available in Russia?

You're right. The long cables are the reason. It's a pity that I don't
know any American manufacturers who sell those filter cables you need,
but if you know a brand named Simprop you might get very good filters
from them. Or you try to install shielded cables where the pulse wire is
protected against interference.

  I was basing the 1 watt limit on a question from the 1988 Technician
class test questions. Question 3A-12.1 states:
  What is the maximum mean output power an Amateur station is
permitted in order to operate under the special rules for radio control of
remote model craft and vehicles?
  The answer was one watt.
At that time, Technician class operators were allowed maximum output
power of 1500 watts on the 50.0-54.0 Mhz band.  
  As I mentioned, these were the rules up until 1989.  I haven't
checked the current FCC regs, but assumed that the lower power rating
for radio control was still in effect.

I know that this isn't what you were exactly wanting, but I've flown a
plane that was made entirely out of cardboard and yardsticks (structural
components that is; radio, engine, etc were standard type equiptment).
This plane had a .40, but was scalable to .60+ and .20-.  I thought it
was painted, but now I'm not sure... it might have had monocoque.
But it was something different.

This is another good example of why Tripoli and NAR have to work together.
Neither organization is strong enough to find government red-tape alone.
Both organizations want HPR to continue.

Now, about what you found out....

Did the ruling just cover RMS technology?  Did they rule on G expendables?
Did they rule on under-G reloads?

Also, does anyone know if current HPR disposables (H & up) are, in fact,
'Banned Hazardous Substances' or something else? In other words, does this
ruling put reloads in the same class as HPR disposables or something even
worse?

Too bad. Their ad is in the latest Tripolitan magazine, which I just pulled

Well, I don't know if they're the best source, but we deal alot with High
Sierra Rocketry, out of Orem, Utah. Some sample prices:

Kit                 List        Their price
---                 ----        -----------
Aerotech ARREAUX    $40           $29
29mm/40-120 RMS     $40           $28
G80 expendable      $10           $7
G64 reload          $6            $4.25

Nits: They seem to get "low-man-on-the-todem-pole" delivery from Aerotech. I
don't know if this is due to lower volume (on High Sierra's part) or if their
"discount" nature makes Aerotech ship to them last.

They are good about backorders, however, and will ship everything you order 
that they have immediately, and ship the backordered stuff later w/o shipping
and handling charges.

To correct some mistakes that I realize I made in my prior summary posting:

1.  The 'video' was sent to the NFPA and CPSC prior to the April, 1992 meeting.
    It was first shown to the NFPA committee members during the April meeting.

2.  All of the results I had written as having been in Feb were actually as a
    result of the April meeting.

3. I also used a reprint of an Apr/May 1992 WARP 9 article for information.

4. All of the SENTINEL and WARP 9 reprints were from a May 1, 1992 'Special

There's some good pictures of this in the latest Tripoliton .... the one with
the V2 on the cover. It's coming soon to a launch near you - or at least me, the
article claimed that they were going to bring it to LDRS XI next month,
driving it from KS to NV will be fun, I get enough wierd looks with my Magnum
tied to the top of my car .... I can just imagine the Highway Patrol pulling
them over - that thing's a monster, (or even worse maybe MPs from some missle
base in the middle of nowhere :-)

The same issue has a lot of stuff from Danville - they make a big deal about
drag-racing some Rocketflite powered birds - hah! wimpy shit :-) at BlackRock
a couple of weeks ago 3 of us drag-raced our Magnums all with K550s and matched 
ignitors - really awsome! - maybe we'll do it again at LDRS?. I got the point
for first down ...

Would anybody recommend any other kits for a person taking that first
