RE: PITCH AND THROTTLE CURVES
You need more top end pitch. Set it for 10 degrees. That will help you stop the descent. Like I said you can add throttle at the bottom of your pitch curve by setting up stunt mode 1 (idle up 1) with the numbers mentioned. With your pitch curve, make your throttle curve in stunt mode 1 (idle up 1) to 35% at low position, 28% at 2, 50% at 3, 75% at 4 and 100% at high. This will keep your RPMS up. Feel free to adjust as you need to, up or down. Also practice slowing your descent rate maybe.
