Air Craft
Datasheet

This is where you'll find actual test data, after we've had a chance to fit some props with various cell counts and record the results.

Mega Motors (the Czech factory) has supplied motor constants.  We saw before with the 22-30-X and especially 22-45-X series motors, that the supplied constants when entered into motor calculators like MotoCalc (www.motocalc.com) gave predicted performance considerably below actual.  But we've done some preliminary testing on the 3-turn now, and it looks like the 16-25-X motors will perform very well.

We'd be happy to have your results to add to our own, so that we'll have more actual data what these superb motors can really do.  If you send results, please indicate cell type, cell count, prop type / size, and rpm.  If possible, use an Astroflight Whattmeter to watch battery voltage, and discard any results which occur at less than 1.05V per cell (indicates battery too small, or weak).
