Getting better
After reinstalling the radio it now transmits at full volume. Sounds great without the engine running but transmit becomes somewhat garbled when in flight and noisy. Much better over all. Gonna play with settings more.
I changed my baffles to have proper taper for my ECI cylinders, added the duct/channel on the back of #3 , an air dam on #1, and plugged all of the little holes. Today on take off I still had 415F on two cylinders at 120 kt climb and 75F ambient. Had to substantially reduce power to control. Before hot to cold was 3,4,2,1. Today was 1,4,2,3. Obviously the #3 duct worked great and #1 air dam was too much. Conditions were warmer and lower altitude so hard to compare Temps to previous flights but guessing I'm about 10 F cooler at cruise on average. Assuming I reduce the air dam size I think that leaves me with #4 a problem during climb only. #4 is middle of the group in cruise.
I've traced my heavy wing to an improperly fabricated outer wing aileron bracket on the left side. I've got to make a new one, there isn't enough room to simply adjust the aileron bracket. A bummer but shouldn't be too difficult.
