Matt,
Sorry my last-minute work situation reared its ugly head. I was looking forward to flying (even in the howling wind!) and to have you try a couple of the props I have.
Do you plan to be in Conyngham, PA next weekend? I am working every day straight thru next Thursday to make sure there is no chance work will interfere with plans.
Can't wait to see your set-up. How is the Teflon coupler holding up?
Bob,
Let me answer the last first: the teflon is holding up to the chemical and heat exposure very well. In fact it is holding up mechanically also, to the pipe and header with virtually no leaking to speak of. The button head screws and the wire ties I am using are doing a very good job. I lost my pipe retainer o'ring last week during a flight and did not lose the pipe.
I doubt I will make any contests until Pocono. If I do, it will be for one day only
Ed and I adjusted the throttle curve to something more workable today. The curve in the TX (the one I had been flying which I didn't check until today) was backwards.
I richened the HS and LS needles some more and it looked like I got most of the sag at mid throttle out of it. Low end is slightly rich but high end is just right. The throttle curve needs a little more tweeking and I think it will be good to go. The engine is very close to being fully broken in now with 24 tanks of about 10-12 ozs each through it.
The prop is cut down 18x12 hybrid, cut down to 17 3/8 X 12. At the last of the day I did a couple really extended vertical checks, rolling for 1000 feet then doing a couple snaps after that, all on the vertical up line, ending it at around 1500 feet. Great authority through out all of that....best yet set-up I've come up with
