First attempt at a scale build

[Bob D]

I am having my first go at building a scale heli by fitting my old KDS 450 QS into a HeiArtist 500D White Fiber Glass Fuselage.

Having a good time sorting out the little tweaks needed to make the build.

I have a question on pitch and throttle curve set-up.

When I first started out learning to hover I set my pitch curve to 5.5 deg mid stick, -3 deg bottom and 10 deg top.

Once I progressed to moving around, tail in, I re-set my pitch curve to 0 deg mid stick, -3 deg bottom and 10 deg top.

I am now reading that for scale flying I should set my pitch curve to 5 deg mid stick, -3 deg bottom and 10 deg top.

What pitch curve do other 'Scale' flyiers use?

Cheers,

Bob

To be honest there is no right or wrong, and you should set it up how you want it.

If you want to maintain a similar hover stick position to your 3D models then you'll still want roughly around 0 degrees at mid stick... Certainly though for the most part you don't need anything more than -3 degrees on the negative side.

Bear in mind though that scale models are heavier and generally spin slower, so will often require more pitch to hover. Personally I set mine so the curve is around 2-3 degrees at mid stick and that seems to give a similar hover stick position overall.

if you are happy with 0 deg at mid then fly that way
but i'd set the mid to +5/5.5 deg with -3/3 at bottom and +9/10 top
this will allow a smoother flight for scale


if you wish to copy the red bull team
then -10/0/+10 with as higher head speed as the body allows

I personally like around 5 degrees at mid stick so that, that is roughly the hovering point. This gives you a much better control over the rest of the positive pitch range. (A full half stick movement )

i tend to go for 5 1/2 - 6 mid on my smaller scale helis and 9 deg at the top which gives a nice control over the model
i do set an idle up with a higher head speed and a lower mid stick pitch for windy days

on the r22 and bell 47 they are running o/+4/+8 1/2
in hold they have -3 at the bottom

Thanks for all the replys.

I can now see the reasoning behind using -3 deg bottom, + 5.5 deg middle, + 9 deg top pitch settings when flying scale.

This will give me better control and 'feel' while trying to mimic real helicopter flying characteristics and also help with the extra weight of a scale model.

I will keep my 'Pod & Boom' heli's -3, 0, +10, while still learning circuits, but fly my scale heli's at -3, +5.5, +9.

Cheers,
