Cruise performance

I actually have an experiment in mind when I mount my GY26s that's along those lines, Farmboy.

I hope you get good results.

I try to envision how a tailcone cupped to mount close to the tire trailing perimeter would help reduce the drag, without being in the way, adding too much weight due to the structure needed to hold it vibration free, and I don't see enough benefit. But if a simple fin would make a difference....the 3:1 ratio may be a hurtle.

I have a mostly stock PA-12 with a 150. I was flying home today a Citabria formed up with a 172 behind me and went smoking by! I thought a PA-12 was relatively fast...
 
I have a Super Decathlon with speed mods, including very long wheel pants with added thingies on the bottom to make you think there are no wheels in there. I cannot tell the difference on or off. I am sure there is a difference, but it is not 5%.
