I have flown with and without it and the plane seems to perform better without. However, the leading edge stays in better shape "with". I am hoping to get some input as to what performance difference, if any, I can expect and, if there is significant difference, what tape would be the least penalty. Thanks for the help. Also, my plane appears to suffer a lot, performance-wise, in the hot climate of summer. It seems to do considerably better in the colder conditions. I am wondering what performance degradation is caused by heated air and if there is some rule of thumb that would help me know what to expect. I have read some performance charts for various planes that show very little difference in TAS from -20 to standard to +20 at altitude. Mine seems to have a wider performance window than, say, a Bonanza. As it is, I only know the plane didn't do very well last summer, did fine over the winter and is not doing very well this summer. Appears to be about 8 ktas down in hot weather. I don't know if the reduced performance is atmospheric or mechanical. Another observation is that the slightest change in conditions from ideal causes a reduction in speed. Moisture in the air, clouds (even smooth ones) or even a slight bit of turbulance slows the plane noticably. I will appreciate any sharing of experiences or insight concerning this condition. Thanks for your help. And, yes, I do know about density altitude and how to compute it. I know it hurts takeoff and climb performance. I don't know specifically how it relates to the cruise performance of my plane. Thanks again for the help.
