Datasheet

Mega has just introduced these new, large Outrunner brushless motors, and they are very nice indeed!  The fit and finish is fine, and there's a lot of copper packed in there!  Mega hasn't supplied actual prop/battery data, so we're going to have to do that ourselves.  Once we have that, we'll look at the motor constants supplied by the factory, see how close they come to reality, and post the results.

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 much below actual, so we want to get it right from the beginning this time.

We'd also be happy to have your results to add to our own, so that we'll have a better idea of what these promising 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).

Mega supplies the pictured 6mm-to-8mm collet adapter (fits 8mm hole in prop, or Aeronaut folder hubs), so you don't have to buy one.

The initial recommendations are:
*41-30-10:  10-16 cells with 12" to 15" props
*41-30-12:  12-18 cells with 12" to 16" props

The Jeti 40-3P or 70-3P Opto ADVANCE ESC (up to 16 cells) should be an excellent match for these motors, but you may want to try the Hacker Master or Castle Creations Phoenix ESC to be sure you have enough timing and frequency settings to optimize performance.  For more than 16 cells, you'll need the Phoenix 60 or Hacker Master 48-3P.

Here are the specs as given by the factory.
