So where was it shown that a 25 oz plane will not fly?  If everyone is 
required to use mufflers, then all the planes will become 3 oz heavier. 
So what?  There are rules for engine displacement aren't there?  There 
are many forms of racing e.g. motorcycles where minimum weights 
are set by rules.  All that is needed is the stroke of a pen.  Once that 
is done, I'm sure someone will start selling break-away mufflers, or 
figure a way to put the muffler behind the cylinder, or develop flexible
soft polymer mufflers.  It's only impossible until you get started.

Well, you don't know me.  I like going back there "year after year

having the NATS in my hometown!  Now this year, my vote is for Golden,
Colorado because that is where I will be...but I might fly back to

By the way, I think most RC sailplaners like having the NATS in L'ville.

Hey, Isky, I didn't see any smiley faces there. Were you serious?

			I didn't think so!


At the CL World Championships this summer, the Russians (well, all
the guys from what used to be the Soviet Union) were there showing
off all of their stuff for sale. The pictures in Model Builder were
ones that Rich (I think) took. You'll see about the same pictures
in Model Aviation when they publish the World Championships report.

Yes, one of the "mufflers" was a white rubber-like. It conformed
to the rules, it didn't do much for the sound level (it's not noise
if you like the sport!), and it cut the performance some.

The whole muffler thing in FAI Combat is a joke. Legislating the
dimensions of the muffler doesn't say anything about the real
question: how do we get the sound level down. Remember the 4mm
venturi? It was supposed to slow things down AND reduce the sound
level! (Oh, yes, less power = lower pitch props = higher rpm = just
as much noise and damned near as much performance.) And then you 
throw in the new, provisional, FAI Combat event JUST FOR DIESELS and 
which require NO (zero, zilch, nada) mufflers, and you have to wonder
where the thinking is coming from. Diesels are not quiet when they are
being run for high performance. A diesel at 22,000 rpm is just as loud as
a glow.

Oh, well, whatever the rules, the good flyers will prevail. And,
I guess, that is how it should be. I just hope the rules-makers
don't legislate the event into oblivion.

Bill Lee

I disagree. Dope and tissue still represents the best low-tech finish if
you are interested in strength and lightness. (All those FF guys would
certainly be using something else if it were markedly lighter and
stronger.)

Interestingly, dope and tissue can be among the finest and most beautiful
light finishes too. If you don't believe it, take a look at one of Windy
Urtknowski's CL stunters sometime. By comparison, even the finest monokote
finish looks downright tacky.

Of course, Windy probably puts in 100+ hours finishing each of his ships. 
There are well over a dozen paint coat/steps involved.. You have to *love*
your ship enough!

I own a Airtronics Fm 4 ch. radio (Tx and Receiver) and have used it on a
gentle-lady ship for a while. This Sunday, the radio failed just I tossed the
plane out on a slope. I observed that the fin and the elevator kept in the
neutral position in the air. They did not respond to Tx stick movement at all.
I did check the radio and tested the servos before the launch.

The plane crashed landed. I was lucky as the damage to the plane is minimal
and nobody was hurt.

I examined all the connections and the radio after the crash and found nothing
abnormal. In fact, I flew the plane for a little while afterwards. It was
perfect.

Question:

Does anybody have the similar experience ? with a Airtronics or a Futaba Radio?

What could possibly caused the failure? Any weak points inside the Tx and
receiver ?  Interference?

Anysuggestions as how to prevent this from happening?

Air comes out in the carb ?? It seems, that something's wrong with the
fuel supply. Are you sure that the hoses are connected to the proper
nipples ? Did you use the crashed tank for your new model ? Did you
check the interior connections of the tank ? The hoses could be
damaged due to the crash ....
Open the needle valve a bit more and blow into the pressure line
(muffler) for some seconds. You must see fuel reaching the carb. If
not, your fuel support still is damaged ...

 Re crashed FOX

 Although the tank isn't in the optimum position, with silencer presure it
 should be perfectly ok..

 I have a really old Webra 60 that has so little compression that you can 
 barely fee it when you turn the prop over. I use it all the time in a 
 Wot4 and it runs fine, probably not a powereful as it once was but more
 than adequate for the Wot4... So discount lack of compression....

 It's obviousy only running on the fuel you're squirting in the carb.. The 
 needle settings shouldn't be that critical to get the engine running, albeit
 not very well. So close to the manufacturer's setting should get be ok..
 set the throttle half open, then you really only have to worry about the
 main mixture needle...

 Are you sure the spraybar area is clear?... I would fill up the tank, remove
 the spraybar and with one filler line blocked off blow down the other and
 make sure fuel comes out of the carb.. Although I haven't seen a fox motor,
 I would be surprised if the needle valve should have a bit of metal on the
 end, it should be a smooth taper to a point...

 One final thing, is it a new tank?  I've often seen the clunk thrown 
 forward in a crash. This kinks the fuel line and you don't get any fuel 
 flow...

Kibo's own glow engines use a special silencer which convert the sound
into a radio-frequency broadcast which is emitted at exactly the
frequency--and air time--of the Fox sitcom "Married With Children."

Gee, doesn't your throttle go both ways?  This is the first time I've 
ever heard anyone complain about having too much power.  The only 
valid reasons to choose the FP are lower cost and lighter weight (not

My interest was tweaked a bit. I've often wondered about the future of

And how do the real combat fliers feel about it?

Anyone have any experience with the Estes Astro Blaster?

I was thinking about getting either this one or the Sig Ninja.

The Astro Blaster sounds really intriguing because it is a canard and
can fly rocket boost, slope, or you can use a dummy rocket motor and 
plug in a .049.  This would work out great for me since I can fly it on
the slope when I'm at school (Torrey Pines site), fly it under power
at a schoolyard when I'm home for the holidays, and fly it rocket boost 
when I want to show off to my friends.

My concerns are that 
1> I don't know how well it will fly on the slope.  For that matter, I don't
know how well it will fly period.  (I already read the Dec `92 MAN review,
but they never mentioned anything about slope performance or much about glide 
characteristics)

2> The elevator/aileron canard configuration prevents stall maneuvers (i.e.
snap rolls and tumbles)

3> the .049 pusher configuration means you can't use a clunk tank (the
clunk will be facing the wrong way) and the QRC/Texaco/Black Widow
engines won't go inverted which, combined with #2, means you can't do many
good stunts under power.

Anyone have any comments on this plane or how to solve #3?

An apt description of my Cheetah - ugly but tolerant of handling (especially ugly
