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.

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?

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.
