Prop down. Don't bother with limiting the throttle travel.

Most ESCs reset the throttle travel each time they're powered up. You would have to reset your throttle to 100%, then power up the plane, then reset the throttle back down. Royal pain-in-the-tuckus.

Limiting throttle travel is also not a real solution. The Amp draw you're seeing on the meter is an AVERAGE. From moment to moment, the battery is seeing small full-current pulses, because the ESC is just a fancy on-off switch. Those full-current pulses are being handled by the ESC and motor. If your full-throttle current exceeds the limits of the motor or ESC, you can rest assured that the limits are still being exceeded at partial throttle.

The best solution to drawing too much current is to adjust prop size down until the current is within the limits.
