Hello,

I am still fairly new to the sport and I am still confused regarding radio programming and throttle and pitch curves. A member let me borrow the book RC Helicopter Primer which taught me much(thx Brian)but I am still confused about these subjects. Could someone please point to some guides on the subjects?

Thx

Thank you for the links.

If anyone comes across a PDF repository of literature please let me know. I like to possibly keep some type of 'mobile' library available just in case I need it.

Thx again.

curves
Pitch curve used to place blade pitch at certain points across the line. They start out as straight lines then curves as you change them. Pitch and throttle are mixed together, let's say you want 5degrees of pitch at 50% stick, move the throttle to half(50%) the adjust the point at 50% until you have 5degrees. The best thing to do is get help or play with the radio until you see how it works. Read the manual.
Throttle curve works the same just with engine RPM. If your still confused I will write a more detailed report, I am on a tablet for now hard to type.

Throttle Curves

Throttle Hold: This is the mode that you "flip" into when you want to perform an autorotation. This mode should be set so that when activated, it will bring your engine or motor down to an idle while offering you a pitch range to auto safely. You can also use this as a safety measure when you're near the machine and you want to avoid having any chance of hitting the throttle stick and spooling up.

Normal: This is to spool up and basic hover mode. You always start up your helicopter in this mode. This curve should give a good balance between power and pitch. You can set a curve that will give great power throughout the full pitch range. Most pilots switch out of this mode once they're up and hovering.

Idle/Stunt 1: This is the mode that most pilots fly in. It offers a "V" curve which allows you to have 100% throttle at both high and low stick. This mode is used for when you get into inverted flight. Most guys also set up this mode for a higher RPM for aerobatic/3D flying.

Idle/Stunt 2: Same as idle/stunt 1, but can be set up with even another head speed if you'd like. I generally have my idle/stunt 2 set at a higher RPM.

Pitch Curves

Throttle Hold Mode: This curve is the same as both of my idle/stunt 1 and idle/stunt 2 curves. It offers me full range from -12 to +12 on my blades, but it will work with the throttle curve so that you still have full range, yet you will be at an idle engine setting.

Normal: This is the pitch range that you will be running in flight mode "normal". Some pilots use -4 degrees at low stick and full pitch at high stick. I use a full pitch range. Again, I just use this mode for spool up and nothing more.

Idle/Stunt 1: This curve should be a linear line from 0-100. This will offer you the full pitch range that the machine is set up for. This is a must have set up for any aerobatic or 3D flying.

Idle/Stunt 2: Should be the exact same setup as idle/stunt 1. Pitch shouldn't change.
