Yes it does. A buddy of mine bought a Trainer and radio off the ceiling of the
hobby shop for $200. Add a $70 OS 40, $40 to the AMA $11 for fuel and he was
'in the hobby'. Pretty cheap by most accounts. He is hooked now and the
expenditures are growing...but that is another story!

Definitely check out used equipment. Shop carefully 'cause typically you can't
return it if it proves to be less than you expected. I generally buy used
radios etc and have had great success. It never hurts to replace servos and
DEFINITELY cycle the batteries to check them out. Also look at the ARF's. I had
one to do exactly what you want to do. Learn to fly. I now only fly build ups,
but that's me.

Good luck!!

Well, time for Dave to rampage a little...  :-)

Do I think it's a "good deal"?  NO!!!!!  

I am an instructor.  I am certified by the club in which I have 
membership, I am a fixture at a couple of local fields, and at least 
one area hobby shop refers beginners to me fairly often.

What is my rate?  Buy me lunch.  Be my friend.  Most of all, instruct new
fliers when you get experienced (if teaching is your thing).  Teaching, for
me, is an enjoyable phase of the hobby, a part of modelling in which I can
help others in learning and solving problems, fly a lot of different 
models, and (I will admit) get my ego preened occasionally.  It is 
rewarding in and of itself.

It makes me angry that a fellow modeller would demand payment for what has
traditionally been an act of goodwill.  Even "professional" modellers do
not charge money for instruction.  (I was instructed in modelling by
Maxey Hester (among others), and got a few words of advice (at a flying 
field) from Carl Goldberg (though I didn't know it was him, at the 
time :-).  I have met many, many, famous, expert model instuctors.  Not
a single one ever got anything but a smile, a handshake, and a friendly
good feeling for his trouble.  It was enough.

This is not a flame at you, Mr. Dude :-); it's a flame at the petty
callousness of some people who would gladly subvert one of the most 
wonderful things about modelling (the spirit of *helping*) in order to 
make a few bucks.

My advice you you, Mr. Dude :-), would be to hang around your local field,
hang around a not so local field, ask questions, go to an RC club meeting,
ask some more questions, and find out who will help you, simply for the 
joy of helping.  You will have a better experience for it.

And lose this guy who would take your money like that.

	Dave Svoboda, Palatine, IL

PS, as I have posted before; if anyone has any specific questions
concerning modelling subjects within my experience, email or post them.
I will be, as will others on the net, happy to answer them.

   At the field where I fly, there are 3 people who have the ASP 108 and 
   I can say that we were unable to get any of them to run rich except by
   doing what you did and restrict the exhaust flow.   I think that maybe
   a carb rework or possibly a new carb (will OS carbs fit ?) is needed to
   get the thing to run right.

Hello Net-

Can someone give me a quick discription of Quickie 500.  I have never seen it, 
but from reading the mail it appears to be an inexpensive method of pylon 
racing.

Is the plane size limited?  What size engines?  I've seen the terms "Scat Cat"
and Nelson Engines.  Any other popular kits or engines?

How many laps do you race?  How big is a lap?

Yes, the change in prop tip speed will be dependent upon the *new* peak 
RPM, and tip speed could end up increasing,  decreasing, or staying the same.  I see your point.

Hi there,
I have an OS 46SF side exhaust , which I ran a 10X7, 10X6, 11X6, and even a
12X6 on for fun. It is ABC and I just run 6-8 flights with muffler to run it
in, set up maybe 1-2 clicks rich from flat out. start running in on the fuel
you intend to run full time. If you dont have a muffler, start with the pipe
long an a 10X6 so it wont come right on (if at all). Long also runs quiet.
From memory I ran the 11X6 on it with exhaust face to crown of pipe about 13",
about 1/2 to 3/4 shorter for 10X6. another writers 9 some inches sounds VERY
short to me. start so it sounds like its coming on on the ground, then fly.
if it comes on in a shallow dive its short; if your level flight is ok, but
your verticals GOOD, its about right; if its quiet and vertical great, its long

Greg - Radio Control Modeler (RCM) did a construction article on a
.40 size autogyro last Spring. I can't remember the issue date cuz
my magazine collection is at home and I'm at work. I believe RCM
also sells the full size plans. Guy powers his with an OS .40 4-stroke,
says its very different to fly, but not difficult if you're the
type that can adjust to the unusual quickly.

I think Embry-Riddle took first or second. They had some experienced
modellers on their team including Todd Lee, an up-and-coming C/L Stunt
flier. They covered this in Model Aviation some months ago.

Thats the second well-known young modeller I know of whos gone there. 
The other one, I believe, was Free Flight wizard Melinda Anderson.

I'm new to r/c planes and I don't know much about Q500 planes or Nelson .40
engines, but I think that imposing restrictions on what kind of plane
can have what engine goes a little too far.  I do believe in safety though.
So I think that correct precausions should be taken into account, like 
standing far enough away incase a plane falls out of the air.  It is not 
a question of banning equipment and designs, (Everyone likes to experiment)
it is a question of how to use planes, so no one can get hurt.

  A couple of things... You can tell 4cyl fron 2 cyl by the sound.  There is a
very noticable change between 4cyl and 2 cyl operation as well as a change in
the amount of fule coming out the end.  The 4cyl is caused by excess fuel in
the system causing the engine to file every other cycle.  Wish I could send ya
a tape of the sounds.  6 turns out is ALOT... but this may or may not be a
problem as long as it runs consistantly at that setting.  If it varies, you
most likely have something clogged in the  carb...possibly near the needle
valve or in the spray bar.  Sometimes this is a small almost invisible piece of
tubing that has been cut off when you pushed the tubing over the brass pipe...
Look real cles with a magnifying glass and strong light with the carb apart and
you should find it.

  I happen to be building a robot.  Now i know this is out of
category but I just realized someone in here may be able to help
me out.

  Fist does anyone know of some mail order companies who supply 
DC motors in all different sizes.  I need one that supplies
information such as torque.  I live in Canada so that every time
i look for something it takes forever. 

  On the same note i need a catalog on small transmissions.  The
types that dc car modelers use.  Essentialy I need to route
the power of a dc motor about 90 deg. and I may need to
change its gear ratio so as to increase torque.  All the guys
in the robotics section gave me suppliers for aluminum and
stainless steel gear supliers. But these supply things either
too big, to heavy or way too expensive.  But I notices
something similar to what I need to my TYCO rc car.


Any help would be deeply apreciated.

 Dan, the EXTRA 300 is probably not a good choice as a second plane. They are fast highly aerobatic and a great 3rd or 4th plane. As a second I would try say Kougar or a Sportster 40-60.

I live in the western suburbs of Chicago and have been flying at least 
3 to 5 days a week for the past 2 years using Futaba Attack and
Cannon super-micro receivers.  Both receivers are AM single conversion.
I also fly with another guy who also uses the same two receivers.  He
uses the Cannon gear in world competition.  I have NEVER seen radio
interference except when flying directly over another transmitter
at low altitude (~50 ft - coming in for a landing).  Even then, the glitch
is minor.  I even fly with transmitters on both adjacent channels -
No Problem!  I rate the Futaba Attack receiver EXCELLENT (the Cannon Rx
is the only one that I have experienced any interference with). 

So...a different opinion.

I've trusted my 12-pound Super Sportster 120 with a Saito 120S to a Futaba AM
radio for the past three years and I've NEVER had a glitch. I've flown it
mostly at a nice, remote field, but I've also flown it in St. Louis and in
Jefferson City, with no problems. It's  a 4FG. I don't fly when there's
electrical activity (ie, lightning) in the air.

Anyway, I've had NO problems with AM.
