John,

You did all the right things !!..............."Fly the Airplane" was the main thing at the time !!........When you

are up to it let us know the extent of damage to that beautiful "Tailwind" also all will be interested in the

condition of the "Marcotte Redrive"..............You made reference to "reading between the lines" from

"Contact Magazine" about the "Marcotte".........Can you educate us about this ??.................

All the Best,

Subject: [FlyRotary] Flight Test

Here is some test data on my 13B Tailwind. Marcotte Redrive, ration 25 x 51.

1st hour

engine rpm 5600 max prop is Fred Felix 67 x 70, bi-cambered

water temp 190

oil temp 192

fuel press 42

ex temp 1600

MAP 28.5

OAT 76

air speed indicated 163

2nd hour

engine rpm 5800 At .7 hr into flight the engine was picking up rpm so I throttled back 100 rpm's and tuned the A/F

water temp 185 mixture and the engine picked rpm to 5800 rpm again. The engine must be breaking in and it was

oil tem 170 running real nice, VVI was indicating climb of 200 feet per minute. At this point the Marcotte Redrive

fuel press 42 started to vibrate so I throttled back to 2000rpm on the engine, by this time I could smell 80w and

ex temp 1600 smoke. I did a 360 turn and I'm flying in the only cloud for 100 miles. It doesn't give you a fuzzy warm feeling going 190 mph and having a fire at 4000 feet AGL. My landing was less than stellar

MAP 27 so will have to repair the plane next winter. I should have been reading between the lines in the

OAT 60 Contact Magazine and replaced the redrive before flight, when it failed the front seal fell out and the

air speed indicated 190 80W followed.

Thanks to all you folks for you assistance in getting the engine running real nice. To bad the redrive was garbage.

JohnD....I was really happy I didn't get injured
