What do you all think of the GY401 gyro?  I wasn't able to get my heli off
the ground today because it seems my gyro went bad and is giving some bad
signals to my tail servo.  What are the ups and downs of the GY401?

Just picked up a second hand heli from a respected shop on
consignment. I'm tempted to take it back for set-up (not sure it's
ever flown) but I don't want to waste $ or wear out my welcome. It's
rolling left, pitching right, engine too rich @ low rpm, too lean @

Just mastered nose in hovering myself. Learning on a mini lama I was
rock solid and instinctual (that is I can hover without "thinking
about it" ) tail in, but found moving to nose in very difficult. In
fact getting so very comfortable with tail in hovering before trying

I can really appreciate the skill and coordination required by those
that fly 3D, how you guys that fly 3D remember where to push your
sticks when the heli is thrashing about in various positions, amazes
me.

Does any one have any flight sim software they want to sell or something
that I can use for my "RAPTOR 30 class rc helicopter" as I have had it for
over 3 years now and have never even flown the thing...

My last two flights (raptor 50) I have noticed that as soon as the main tank
is empty and the header tank is just starting to go down I lose power,
What's up with that?
I cleaned the fuel filter before my flight today but that didnt change a

Guys, just after a heads up before I buy...
I am about to chuck a Rappy 50 together, with an OS 50.  I'm thinking of
using 9001s on cyclic, 9253 on tail and 9202 on collective.
The 9001s work well on my Sceadu but that "only" got an os 46 in it.  Reckon

When's that fekkin wind going to go away?  I haven't flown for a whole month

set.

A question.......If I set all the pairs of control rods accurately in length
using a vernier to within +/-0.1mm, (0.004 of an inch for the older ones
amongst you, like Kev), of each other will this ensure even flight with no
trim, or would I still have to take it to the field a do ...

How do you guys normally clean your engine after running for the day?
Back when I used to race boats it was normal practice to use some
laquor thinner followed by trans fluid, spinning the engine between
each step to work the fluids in (of course that was with highly

I'm wondering what servo's I should be using on my lenmount dauphin 1/7th
scale. It has the Benzin Mechanics and a fenistron fan.
Also I have bought the Vario blades but they dont seem long enough to give
it a real scale look.

Did my first nose-in hover today after much practicing on the hoverfly ,
plucked up enough courage to try it on the Raptor and it seemed a bit too
easy!
I thought nose-in was the hardest to master , but I have more trouble side

Is Rotor Sport still going?
Are there any other dedicated Heli mags available?
WHS doesn't seem to have any.
