raptor and sanwa rd 6000 - help with neg pitch setup

Post by leemarsh.. » Tue, 25 Jul 2000 04:00:00



Hi,
I have a raptor set up for a beginner (which I am) and it has been
suggested I set it up with about 2 degrees neg pitch at bottom.
It is currently zero degree pitch bottom, 6 at hover and 12 at top.

How do I do this.  I thought about adjusting the length of the
turnbuckle from the collective arm but this will change the hover and
top pitch surely.

Is it done via the radio - I have heard of ATV - cannot find this on my
set - Can anyone help.

As I said I am a beginner with limited experience of all the
adjustments needed.

Sorry about this - but many thanks.
Thanks to David Ditch for his help.  Throttle screws have been set and
clutch mod done.

I think that you should leave the bottom pitch at 0 degrees for awhile.  If
it won't come down quick enough then maybe increase it to -1 degree.

The low pitch end determines the sensitivity of the Collective, and as a
beginner, I don't think you want an overly sensitive collective unless you
like repairing Heli's.  The positive pitch is set to not excessively load
the engine and +12 is alot unless you got some kinda really high output
engine in your Raptor.  I had my Raptor set at 0 for the low,  +6 for hover
and + 7-8 for high until I could hover easily.  I am now forward flying and
I have -1  ,  +6  and + 10.  For throttlehold ( autorotate) I have -3 and
plus 12.

I set all my pitches with the radio Pitch adjust.

Bob,

Thanks for your advice, By pitch adjust on the sanwa I guess you are
relating to the pitch curve adjust am I correct ?  Sorry for my lack of
knowledge.

I set the Raptor up with +12 at the top end whilst referring to the
recommendations in the manual.  What effect will it have on the heli
reducing it to +7 or +8.  I do have problems getting the heli to come
down and I feel the head speed is much to low when it finally does
start dropping and then I have to apply a lot more collective and
throttle to stop the descent rate. Any suggestions welcome

Is it easy to use the Pitch adjust?

Thanks again

Lee

Reducing it to 7-8 will make the Collective less sensitive so the Heli
won't shoot up too high.  Read this on the Heliproz website. They tell
it better than I can

The engine will never pull 12 so the top end for normal flight mode
should be 9.  12 would be for auto's.  If your learning how to hover,
I would leave it at 0.  Negative will just cause too many problems if
you panic and pull the throttle out.
