Don:

I have been helping an SO team last year and this, and the Hip Pocket site has been great.

We are using a "bucket prop" from a Solo beer cup, with a Bill Gowen style hub for flaring. We only have two carbon rods because it is so small this year.

We are also finding with the small prop and similarly thin rubber that the rubber falls off very fast, so keep track of how many flights on a piece of rubber in your data. More than 2 or 3 you can use for trimming purposes, but not so much for optimizing duration.

Thanks for the reminder about Hip Pocket Aeronautics! I'd heard of it on this list before, but not bothered to look at the site. I did now, and immediately bookmarked it. It looks very promising.

I've offered my meager skills to help a local young modeler trim his already built Science Olympiad model. I may find useful info at Hip Pocket, as well as this list. I think I need to study the rules. It seems likely that making a prop, if allowed, could increase endurance a lot from the standard heavy plastic unit. There is the "slight problem" that I've never made one, even cutting blades out of the side of a plastic tub...

I do know he'll want to get the CG rearward and the plane trimmed for slow flight. What I'm not sure of is how slow. In full scale aviation there is a speed below which it takes more power for level flight, which is not what is wanted here, with low and limited power. Is there a similar situation with indoor, and how can you recognize the optimum speed if there is? Just keep trimming and recording results, and hope conditions are constant enough to make them meaningful?

Thanks,
