View Full Version : Typical Setup for Scale?

Okay, here is the newbee again.
I am building my first Scale Heli and hope to get some answers and/or opinions on setting up the throttle and pitch curves for flying scale.
I assume I would only use the normal curve for both the throttle and pitch curves.
I fly electric and the normal throttle curve I like is 0, 65, 85, 95, 100. Is this okay for scale or should I change it? Multi Gov recommends 0, 40, 65, 85, 100 for normal flight.

I bought a governor (eMulti Gov) and want to know what headspeed I should use. I set it for 1,700 for now, but was told (by an inexperienced scale pilot) that 1,400-1,600 was more desirable for scale. Is that correct?? Is 55% of throttle stick input a good setting for the governor to kick in?

Now for the pitch questions. I think I should set low stick at -2 to -4 degrees, mid stick at +4 degrees and full stick at +10 degrees. But how do you do this, electronically (pitch curve) or mechanically?? Is this correct or should mid stick be at 0 degrees like 3d flying??

Thanks so much

Flying scale or 3D, you should always fly in Idle up.
Normal mode should be used for take off and landing only.

Think about your normal throttle curve settings, 0, 65, 85, 95, 100.
If flying high in the sky, and pull your throttle stick down to descend, you're going to be dangerously dropping your headspeed. You'll lose tail authority and stability.

Once you're off the ground, you should switch to Idle up.
Your throttle curve should be a flat 85% to 92% for governor mode or 100-INH-92-INH-100 for non-governor mode.

When you're in flight, you want to control your flight speed, ascent and descent via the blade pitch not your headspeed.
Your Normal Mode pitch curves should not exceed -2, you don't want to pile drive your heli into the ground.
Normal ~ -2 to +10
Idle Up ~ -10 to +10

Mid stick should be 0 in all modes.

A slower head speed is not desireable for scale. Think about it, you're going to need more head speed to compensate for the extra weight.
You'll more likely have to use the largest pinion rated for your motor, or even upgrade from your stock motor and ESC.

All I fly is normal mode. I setup all my Idle ups to the SAME programming. I change Nothing. My Super Puma that WON the Nationals in 2005 runs a Headspeed of 1250 (Mind you that it is a Gasser), Gyro in Normal mode (Easier for Scale Flying) Pitch Range is -2 to +10 .. I fly Hover at Half Stick and use my thumbs ;)
Hope this info helps you on a wonderful journey of Scale flying!!

For me same as Dr.Tim I guess I got use to fly it scale that way and its going well. :D
