Thanks Tracy, and all other well wishers. I really appreciate your
comments.
I have some indication that the temps might not have been as high as I
thought. I need to recheck my calibrations. I was also seeing 7500
rpm at about 100 mph and climbing at 500 fpm. That doesn't leave me a
lot of room to go faster so I think my prop isn't going to work even as
well as I had hoped. I will just call this my Cessna 150 emulation
mode.

Subject: [FlyRotary] N93BD BD-4 First Flight
I finally got my plane in the air, lifting off at 7:50AM this morning.
OAT was about 40F. Flew for about 20 minutes, did one stall and landed
to check everything.
I bobbled around a bit on take off getting used to the control feel.
Landing was uneventful.
I will need to do some work on cooling as I expected. The oil cooler
location is poor with not enough room behind it and oil temps are
running about 10-15 deg warmer than the water. Both are too high for
summer time flying. Max oil temp was about 220F, so it was higher than
I wanted to see. I also want to recheck the calibration on the sensors
just to make sure I didn't mess that up.
Another rotary is now flying at least a little. Send me one of those
buttons Tracy! :)
