I just started having trouble with my .46 in the nexstar bogging bad during transition after it idles for 3 or 4 seconds. I believe it was directly related to the new "blue thunder" fuel. I came home and screwed up the low speed setting and couldnt get it to run right. But it did transition better. Im jst not gonna fiddle with it until I get back to the field and get the fellas to take a look at it. Oh and on the second day the guys yanked that high speed adj. limiter thing off. The poor transitioning engine screwed me up a few times on botched landing attempts. couldnt get power right away to pull out of it.
