/* ---------- "Tantrum Folding Wing HLG Review" ---------- */
I finally flew my Tantrum hand-launched glider (HLG) last week.  It is
the first time I've tried HLG.

I'll probably build a more conventional design,
like a Skeeter, next (anybody have any experience with that kit?)
- Bill G
************************************************

   I have a Skeeter at home, it built up quite easily. You have to be careful
with the trailing edge, and keep it sharp and accurate as the airfoil desgin
requires a precision trailing edge for best performance. Since there was 
enough spar excess length, I built mine with two extra panels of wing span. My
kit came with some extra wing ribs, making the mod's easy. I also added a 
1/8" strip of carbon fibre strip reinforcement to the lower wing spars as I
wanted to use a short high start. I didn't want to destroy my arm too much
overdoing it on the handlaunching. I have no problem handlaunching it up to
about 75 feet altitude, higher if you want to really throw it hard.
   The Skeeter definitely requires a small receiver and micro servos. The
receiver goes under the wing at about the CG point, and it barely fits. The
two servos go end to end in the cockpit area, and they barely fit, the battery
(in my case, I used a 270 mah pack) barely fits in the nose. I had too break the
pack apart and do a bit of soldering and wedge it into the nose. After putting
in the pack, I installed the forward servo rail and mounted the forward servo,
   But it does fly great, very little drag, if any is worth considering. To me
it seems it needs to fly and cruise a bit faster than the regular types of
gliders. But when you find a thermal, you can tightly turn into it, and stay
with the thermal as needed. IMHO, I think it is a really neat HLG and the 
price is right too.

There isn't anything magical about dual conversion + AM. Dual conversion
simply means that the receiver uses two intermediate frequencies instead
of one. Single conversion receivers use 455 KHz for the IF, so the osci-
llator crystal on the receiver (which is mixed with the incoming RF) is
455 KHz above or below the frequency to be detected. A filter then admits 
455 KHz to the rest of the receiver. Problem is with the megahertz wide band
we operate in these days the frequencies at the top and bottom of the band
may interfere with the ones in the middle. 

Double conversion receivers get around this by using a 10 MHz or so IF,
with a 455 KHz second stage. Such receivers are also supposedly better
at discriminating between adjacent signals. 

Now: Whats to prevent someone on a totally different band (i.e. 10 MHz
away) from interfering with you?

Well, I suppose the only person whose pulling your leg is yourself!  Just 
found the January/Febuary 1987 issue of SCALE SHIP MODELER and on page 40 the
article "The Royal Navy's M-1 for R/C Combat" written by Cliff Shaw describes
the 1/144 scale submarine with functioning gun he built.  In it he also has a 
picture of a 1/144 scale torpedo boat he describes "with functional torpedo 
tubes and full R/C capabilities for use in wargaming." 

The 1/350 Lindberg Bismarck can be radio controlled.  Of course, none of the
guns work.  You can sail it around your swimming pool and play with it as a 
"toy."  Look for the article in SCALE SHIP MODELER of November 1989 by Paul 
Spielberger.

Better check your facts before you ramble about whose leg is being pulled!

I just saw a nifty blurb on SportsChannel Chicago about R/C flying. The showed
a boy learning to fly a Hitec/RCD electric glider with a Hitec/RCD radio. They
also showed the RCD/Hitec sponsored unlimited races in Madeira, California. One
scene has an unlimited plane with RCD in huge letters on the bottom. They
showed how the Hitec trainer cord works.

I wondered who sponsored this? ;^)

Disclaimer: This posting is a personal opinion and not that of Kronos Inc.

I agree strongly that the first plane one gets should be bought used, or
be an ARF or an Aircore.  Even an ARF takes a while to build, for a first
time builder.  The Aircore does too, but it is unlikely to get destroyed.

I have bought three used planes.  They all cost $200-$225 and came with
an OS40-FP, Futaba 4 channel AM, and ARF trainer.  Except the latest one
is a low wing ARF with a Fox .40 and a 6 channel FM, and wasn't finished.
Oh yeah, I also got an Eaglet with OS.25-FP and antique radio for $90.

Buying a used plane allows one to fly immediately.  You get introduced to
building skills by repairing it!  Also, you can start working on a full
kit while you have something with which fly.

A new kit, radio, engine, covering, tank, wheels runs about $350 and many
hours to build it.

P.S.  It's true that "anything will fly"; I've seen it.

I fly an Elder .20 with  an OS FS .21 (predecesser to the 26).  It flies
with no problem, but the plane  doesn't accelerate  the way it would
if it had a two-stroke in it.  I recently pu on an APC prop, and the
performance difference was extremely noticable.  I used to only be able
to do a couple of loops before running out of steam; Now I can loop it
until it runs out of gas.

Connect the top black wire to the white wire, that is the signal.
Connect the middle black wire to the black wire, that is the gnd.
Connect the black w/ red wire to the red wire, that is the positive.

If this does not work, then switch the two black leads.

Date: 9 Sep 92 00:37:19 GMT
Organization: HP Lake Stevens, WA

I'm thinking of upgrading my RC helicopter flight simultor and would
like opinions from those who have seen more modern versions than mine.
I have the old "Dave Brown" simulator.  I'd give it a "C" and am
looking for something which is "A" or "A-".  I know of 3 options (by
the way, this is for PC compatibles -- mine is a 386sx-16MHz but a
fast 486 is in the near future).  1) RC Aerochopper (Ambrosia), which
as far as I know is not done yet for PC's; 2) Skylark (digital Wonder
Works) for which I just saw an ad in Model Aviation, requires a slot,
and is $265, or 3) upgrading Dave Brown (apparantly you get airplane
and heli and the graphics are better).

The money really isn't the issue -- I'll pay the $265 IF IT'S WORTH IT.
But I don't want to pay big bucks for another "C" grade simulator.
If you've seen these, and especially if you've seen more than one and
can compare, I would like to hear your opinion.  What I am especially
interesting in is a simulator that feels "real" in hover.  The old 
Dave Brown just doesn't seem unstable or "noisy" enough to me.

Reply-To: hutto@smtc.engr.scarolina.edu

There is a brand-new (well, 3 weeks old) flat carpet track here in
Columbia, SC.  This past Sunday, I borrowed a Lynx II Elite from the
track owner and raced in the track's first-ever road course race.
It was also the first time I have ever raced anything but off-road
cars in dirt.  As luck would have it, I got to the track 40 minutes
before the race started, so my experience as of when my first heat
began was a total or two, count 'em, two packs of car setup/practice.

Considering that I didn't know what the heck I was doing, I would
say that the Lynx did a fine job of keeping me in the race. We only
had 6 entries, which we split into two groups of three since all 6 of
us were new to this whole concept (well, actually, a couple of the
guys had raced in parking lots several years ago).  I qualified first
in the B-main (4th out of 6 overall) and finished second (5th out of
6 overall).  More importantly, I turned more laps each heat and turned
a "best lap" time only 1.2 seconds slower than the fastest guy (and
A-main winner).

Last week I posted my dilemma about whether to buy the used Lynx that
I was borrowing or get a new RC10L (fiberglass) to be like everyone
else at the track.  Well, after the race I returned the borrowed Lynx
and bought an RC10L kit.  When I got home Sunday evening, I logged in
and read John Hamilton's offer to sell a graphite RC10L for $100.
That's about what I paid for my fiberglass one, so I was kind of down
about it until I started assembling my car Monday morning.  Once I got
started, I forgot all about being dissapointed and just started looking
forward to racing a week from this coming Sunday.

I'll post a followup tomorrow with a few questions for the RC10L experts
out there.  I've got the car ready except for mounting the electrics and
painting the body.  I've ordered an Andy's Lotec GTP body, which should
be here later this week.  I'm going to paint it white with Pearl Purple
highlights down the sides and along the spoiler.

I have also used all three.. Skylark looks VERY sharp, but I own
Aerochopper (I got a used atari for $100 just to run it)  The only neg
of Skylark is that the heli in RC mode ALWAYS stayes in the very center
of the screen and your viewport changes.. comming from Aerochopper
where the heli will "fly" in the center part of the screen without
moving the view port (untill you get close to the edge), Skylark is
annoying. (BTW, Aerochopper will do Skylark center mode) The math on
both Skylark and Aerochopper is great, much better than Dave Brown.

I have a Dynaflite fun scale Corsair.  It flies quite nicely with a ASP 46 ABC.
I built it stock except for the aileron linkages.  I used two servos just outboard
of the gull joints with straight pushrods.  The kit calls for torque rods with 
sliders in the ends of the ailerons.  I also added twin Vortac bomb drops.

Bottom line.. Not very scale but fun to fly (Fun Scale).
