Model Forum / Radio Controlled / Helicopters / March 2007

Ok guys, how come the old helis would thump thump thump thump thump when
they flew overhead?
The newer ones sound just like planes, even in a hover.

Being new to the hobby and having to wait for the snow to melt here in NH. I
am sitting here pondering the following question. Does anybody make a heli
with 2 main rotors like the "chinook" troop carriers?  I've never seen one
advertised?

There's been some complaints about this newsgroup being dead so I
thought I would add a post.
I'm sure someone here has some experience with real helicopters.  My
question is this:

Did anyone try running RealFlight 3.5 on a laptop?
If so what make and model please.
I have to buy a laptop, and can't get any info on integrated GPU's with
shared memory.

I'm trying to build my own motor and I want to build it for a specific
kv. I know the kv rating is inversly proportional to the number of
windings on the armature, but I can't figure out the relation between
the wire gauge and kv, or it there are other factors which effect this

Did you guys see the TV program "Maximum Exposure?"  WOW!
This guy is landing the coolest, 2 seater conventional (tail rotor) heli
I have ever seen.
He's 20 feet up, forward speed 5 mph, light breeze.

just a test

I placed a couple of NEW main shafts on a piece of flat black ceramic with a
bright light on the opposite side to my eye.
The visible light between the shaft and the ceramic moves from the middle of
the shaft to the ends as the shaft is rotated.

I shorted it out earlier today and burned the glass fuse and now I can hear
it buzz in a quiet room. Is that normal or did something else go besides
the fuse?

Just noticed after some mods that one of my old heli's has a 'C of G' about
3cm behind the mast.
It seems to fly fine to me but is there any reason why the 'C of G' should
be under or in front of the mast.

Best flight simulator for newbie to RC helicopters?  Have been flying RC
fixed wing for years but have at last want to got to the helis.  Want to be
able to connect to my own Tx (8UAPS) or similar to the Great Planes flight
sim which comes with the Futaba box.

Is it possible to test AR6100 receiver without having anything other than
transmitter? I thought about powering it from a battery and using LED to
see if I'm getting a signal from the transmitter but I'm not sure how to
connect it.

What 24 hours and no bloody posts,what sort of group is this?
Come on heli ppl get postin.

A bit help required here please.
After a fairly major ding and breaking tail boom on my Sabre I replaced the
boom.  Removed tail rotor motor put on new boom and re soldered the motor
up.

I'm considering trying to loop my helicopter (Falcon 3D) and was
wondering what specifically I need to do.  I know it's easy enough to
do on a plane, just pull back elevator and let it come around, but do
I need to do anything different on a heli?  I'm not looking for a
