| After flying with Idle-up1 mode while headspeed is 1700, I switched the flight mode switch to Normal and start to descent. About 5m above the ground, I pulled up the throttle stick to stop the descending. At the moment, the engine rpm is increased to very high. but the clutch is not engaged. So I have to do emergency autorotation. I got this symptom when I use 30% coolpower fuel with stock muffer or 15% powermaster fuel with Hatorri tuned muffer. But If I use 15% powermaster with stock muffler the symptom is not appeared. but It cannot make enough power.
My cal 30 is equipped with GV-1 governer and set S1 to 1650, S2 to 1700, and S3 to 1750.
How can I cure this symptom? Any small clue or advice would be really appreciated. |
