View Full Version : Counter-clockwise rotating blades.

Hi there!

I am trying to find an electric model heli which has blades turning anti-
clockwise instead of the usual clockwise rotation. Does anyone know a
model that has? I have searched and searched some sites but cannot find
any that have the anti-clockwise rotation.
The reason is because I am putting together a twin rotor heli and I
already have the clockwise rotating rotor, but now need the anti-
clockwise one.
TIA!

This might be a stupid question, but why don't you just change the polarity
of the motor, re-time it and do it that way?
Can't you reverse the pitch linkages to the blades?

Just a thought that I am sure you have already had!

Yep, I thought of that, but I was unsure that would give effective
control. Not only that, but I was going to use cheap fixed-pitch type
blades so I didn't need to use a CP upgrade. I don't like the idea of
just putting them on upside down. I just can't seem to find any models
that have the blades facing the other direction for anti-clockwise
rotation.

Yes, Hirobo has a twin rotor helicopter. Take a look at this site

If the blades are symetrical then upside down or right way up, they wont
know!

Ok cheers for your response. I find it strange that there are so many
models that have blades turning clockwise. It almost seems like standard
with models.
I'll check the symetrical blades out.
Thanks!

That's just a fluke related to which way our glo engines turn. The engine
crankshaft turning counter-clockwise, directly geared to the helicopters main
rotor mast, thus spinning it clockwise. The few counter-clockwise rotor
systems I've flown either had a two stage reduction between the engine and main
rotor mast or had a gas engine that turned the opposite direction that our glo
engines do.

It really doesn't make much difference either way. The only time I "really"
prefer a counter-clockwise rotation is on a scale bird. Watching a Jet Ranger
fly around with a clockwise rotor system just doesn't look right! ;-)

Fly Safe,
Steve R.

I know exactly what you mean. I have always prefered counter-clockwise
rotation blades. The reason I think was because when I started getting
into heli's my favourite was the Jetranger. I always liked the way the
blades looked when doing a turn away from observation, especially when
going fast. It stuck since then, and I was a little disappointed when I
saw models with clockwise rotation.
It sounds strange I guess, but it's just my personal preference. :)

You mean you can TELL which way the blades are turning when they're flying
Steve?? I want your eyes. (Get him guys, I'll get the knife!!!!" :-)

Easily satisfied with the purchase of a Vario machine. Most of those are
anti-clock which looks wrong on an Allouette:-(

Be careful what you wish for, Beav! <g>

At almost 48, I'm in bad need of an updated prescription on my eye glasses.
:-(

It's just that spin up before take-off and the spool down after landing.
<shrug>

Fly Safe,

I've got a few years on you Steve AND I've been diabetic for donkey's years.
Fortunately my eyes are unaffected.

I know, I was just joking. I can still fly a "proper" rotating Jet Ranger
though, coz I've got the Kavan here.

Wow there's some nice looking heli's there.

Thanks for the link... I liked the video section. :)
