| rcjonYou are running max blade pitch of 8 degrees and you are bogging ????? I currently have my Vibe set up for +-15 on collective with +-8 degrees of cyclic! Yes, if I accidentally hit high collective and full cyclic at the same time I instantaneously get a near blade-stop type of bog, but when managed correctly, the performance is incredible. In a straight up power climb, it doesn't start to bog until I go past approx. 12-13 degrees. I'm running 30%CP in a YS50/MP5SB combo. Regular style Radix 600s. Digital cyclic ring. 2075 headspeed.
Have you checked the vent line where it goes between the tank and the middle main shaft bearing ? That's a sharp edge with minimum clearance. I pulled that bearing block out and radius-ed the front and back edges so that it didn't cut into the vent line or cooling shroud. If you got a hole there and lost muffler pressure it could be going lean at power. Do you have good smoke ?
