Travis,
It sounds as though the airflow into the cowl is changing the fuel mixture (leaning it). You may want to try removing the velocity stack.
The other thing it could be is the velocity stack is to close to the inside of the cowl. I had this happen on a Cap. It would change in KE in either direction. Again I removed the stack and all was well
Well, the thing is, my velocity stack protrudes out of the cowl. My motor is still a little rich on the low end so leaning that out some may help. I do have a pressure line running into my fuse. I am not familiar with the RCBlimpPro carb plate. I will do some research on it.
It does seem to be worse when I am doing a left-wing-down KE. Maybe it is the way the air is flowing over the cowling at high alpha KE.
Thanks for all the input though. Between ya'lls help and me fiddeling with it, I am sure it will get straightened out.
Travis
