throttle curve

Here's an area where you can ask any kind of question about RC models and find a whole lot of useful information to help you get started.

Not normally used on basic fixed wing, required for helis to match rotor speed (hence torque) to pitch curve according to Tx stick position.
Normal throttle follows a linear pattern, smooth and even transition from 0 to 100%. Applying a throttle curve can compress or expand throttle percentage in a given stick movement. :D

Wow! I had no idea you has all that smarts... :P

I only have a small amount, but spread it like Pecks Paste "a little goes a long way" :lol: :lol:

Spend a lot of time on my heli before it bit into me. Throttle and pitch curves were essential for stable flight, had to be set to ensure you had sufficient torque and head speed. Pitch curve generally started at 50% throttle you then adjusted the curves according to your ability. Very much like using D/R, "slow curves" for easier control, "fast curves" for experts and radical flying. ;)

I've also used a throttle curve to limit my ESC Amps. I had a 25A ESC on hand but was waiting on a 40A which the plane really needed, so I used a curve to limit my throttle until the bigger ESC arrived.
