FYI - just got home from the Texhoma 100 Air Race. The race was fun and
lots of nice people participating.
On my flight back to Florida, I averaged 200 knots GS at 11,500 and 13,500
thanks to a nice tailwind. Some segments of the flight were at 210 knot
GS. A long trip is a lot better when you can go fast.
A rundown of my numbers -
Alt - 11,500
2410 RPM
19.8" MP
9.7 FF
144 KIAS
174 KTAS
200 GS
Alt - 13,500
2300 RPM
18.4" MP
10.3 FF
136 KIAS
169 KTAS
200 GS
I just can't get the low FF numbers that some guys are getting. I leaned
until LOP and the engine began to stumble. I enrichened back to smooth and
peak to get the FF numbers above.

Hmmmm.... Lower RPM, MP and TAS but higher fuel flow. Something is very
wrong. Are you sure? 2000 ft higher would not explain this. Maybe
mixture distribution problems?

Subject: | "Worn Out" CT-Q67 Cable Assembly (Warning!) |
Dear Listers,
At 170 hours on my RV-8 now, the Prop control had become increasing more difficult
to move starting around 100 hours. The Mixture and Throttle have worked fine
and continue to. All three controls use the standard "Green" control cables
from Vans, typically a "CT-Qxx" part.
A couple of weeks ago, I disassembled the Governor end of the assembly and made
sure that there was no binding or issues on that end. I even lightly lubed up
the various moving bits. Yesterday, the Prop control became so difficult to
move that I had trouble cycling the prop during run up. I pulled the whole throttle
quadrant installation apart today to have a look. I got the cable completely
out of the airplane and there are NO outward signs of wear or abuse of
*any kind*. But even with the cable completely out of the plane and nothing
connected to either end, it is almost impossible to move the cable!! I have a
new CT-Q67 cable assembly for my front-mounted governor installation and I'm
going to install that next.
But, I wanted to give everyone a heads up on these CT-Q controls. These things
are built like they go on a Caterpillar Tractor, so I can't figure out why they
would wear out like this.
If one of these controls starts getting stiff and tight, its probably not going
to get any better. Replace it before it becomes a safety issue! Not a big deal
on the Prop control, but on a throttle or mixture it could be a serious concern.
Best regards,
Matt
