Bender Baffle or Baffled Bender. :p What ever it works, but I think Marty S. actually invented it. ;) |
You mid-western guys are a pretty humble bunch, seems no one will own up to it. I praised Marty for it and he passed the buck to John and I don't recall who he blamed it on. It's a must have if you fly in cold weather at all. The oil cooler damper is a real fuel saver. The one I am using works very well and can be used all year long. Dave Valcek's modification is more functional in that it allows the oil temp to be dialed in in the same manner as the Radiator damper. We are thinking that if he flew into a milder climate, it would have to be removed prior to arriving in that climate. Where we live they are very nice to have! Merry Christmas to all!

;) I went up again this afternoon for an hour. Ground temps were 16f, temps aloft 40f. Visibility was 5-6 miles due to heavy haze. Scoped out my favorite deer watching area and saw 300 white tails bunched up like turkeys. Winter is setting in pretty hard around here with 4-6" of snow cover to hide food for them. |
Thanks Dave - -
makes sense. Originally I was worried about having to adjust the Heater Damper Door a lot, but actually I find I don't have to. If I am just bumming around ( as usual ), I fly at about the same ALT, so I don't have to adjust it much at all. Just watch the temps on take-off, and adjust it a little for the days temps, and it works well. Sure makes it an all season plane. Any day it is not too windy, I go for a flight.

Heater temp
I take it that the baffle is for the oil cooler adjustments. Is there something that would make the cabin heater work better? I just get fast moving air that is not very warm.

Hey Richard - -
go back and look at post #10. That will show you my original post.

The damper we are really speaking of is for the coolant radiator and allows you to dial in the temp. in the cockpit. You can find this little marvel up in the modifications thread.

Humility
Dave. Before I forget...you are oh so wrong in telling that group they are a humble bunch of midwesterners. In other less formal gatherings they wear robes, chant and perform serious chest-thumping. In other words, they are normal American pilots.

Guys I figure I will ask this thread since it appears to be related.. how cold is too cold to fly? I don't mean being comfortable in the cockpit but rather for the Rotax and the carbs. I ask this because a friend and CFI was flying a Rotax powered low wing two winters ago. She took off when it was about -5 ambient temp in Denver. The wind chill dropped it below that. She took off, went once around the pattern and did a low approach over the runway. A bit more than halfway down the runway the engine quit. She was able to get it onto the runway and stopped. The A&P suggested that the severe cold weather contributed to the carbs inability to properly operate. There was no other mechanical issue found.
Not trying to derail the discussion but I am curious how cold others are flying their RV-12's? Living here in CO, we get our share of colder days. I like the rest of you love to fly in the colder air in the winter in my Rotax powered Gobosh while trying to endure the temps to continue the build. Carl |
