Hi Bill

We don't always agree on things but you are on the money on this.
Low ceiling flying with duration models is all about cruise time and using the turns efficiently. The longer one can spend climbing to the ceiling the less time spent bouncing around the ceiling and the longer the flight. Even with VP props on F1D I use a larger motor cross section in low ceilings than high. The goal is to use up the turns in the cruise and the larger motor give a little more rpm in the later part of the flight which should and will increase the time.

When working with students just teaching them about washin and winding will often double their flight times, even with poorly built and heavy models.

  First off we're talking about low ceiling flying - Cat I and Cat II. If you're not very knowledgeable about indoor duration flying we're talking about typical school gym situations with ceiling heights of 20 to 30 feet.

  Duration is dependent on the amount of energy you can use - not the amount you can store in the motor. The rest of the story has to do with rubber torque curves and the torque requirements of the model. I'll leave all that to anyone else who wants to have a go at it.

  "It's wrong but it sounds good."

  What's wrong with it?
