So we pulled my vernatherm, and it doesn’t have any obvious signs of distress, though the marking on the seat is a bit uneven around the circumference. I’m looking for another unit to try, and Jerry has offered his if I can’t find another within easy reach. I’ve read that these valves can fail with […]
Read MoreAnother disappointing weekend down. I was hoping to get a flight in this weekend after we replaced our hoses with 3003 hard line. This is essentially the exact same configuration that we flew without issues in 2008, the only differences being that instead of a 3-way valve up front, the second nose cooler has been […]

Wow was it muggy today. Jerry graciously offered to loan us some 1/2″ 3003 AL tubing to try. As I mentioned yesterday, I wan to try the larger hard wall tube to see if it increases the flow enough to really affect cooling, and if so I’ll get a harder alloy for longer duty. We […]

Well last night was a real disappointment. We flew with our instrumentation, and our temperatures went up. The oil cooler in the nose was reducing the oil temp by 20 degrees, which seems to indicate that we’re not getting enough oil flow to the cooler. In other news, the manometer did NOTHING. Yea, go figure. […]

We were rained out of our test flying last night, and probably will be again tonight. This is very disappointing, as every day I feel like we’re learning more and getting closer to solving our oil temperature issues. What we have done in preparation for that next test flight is installed vortex generators ahead of […]

I’ve been ordering supplies like mad that I thought might help us with our oil temperature issues. I’ve got a 2-pass Positech 4218MN oil cooler coming. It has more tubes than the stock cooler, and being two pass should have nearly 1/3 more heat-rejection capacity than the stock cooler. I’m hoping we can mount it in the […]
