Hi Sky wagon,
I presume your the skywagon on the Back country site who asked the question about cooling.
If so - I have been testing my bird and have 16 hours on her. And some interesting results on the cooling. I was getting 400 deg plus on the hot days and up to 450. I have been working on a few things and it was pointed out that because I had ECI barrels and they were tapered, the baffling that I had sent did not fit them. So I have made up 3 fillers. two for the front and one for number 3 rear. Only had one flight so far and temps are down 30 deg I think. I should have noticed this but I just thought that I had the correct baffling sent.
