So the Phantom 3 isn't better than Phantom 2? Really?For every upgrade there's a downgrade. Just because it's newer doesn't mean it's better.

Haven't you been paying attention? The Phantom 3's all have cracks!So the Phantom 3 isn't better than Phantom 2? Really?

Mine doesn't, 150 miles with over 100 flights. No cracks yet.Haven't you been paying attention? The Phantom 3's all have cracks!
I think I do, and I also recognize when people are overstating things, blowing things out of proportion. For "Every upgrade" there's a DOWNGRADE? Really? Very exaggerated.Geeez! Obviously you do not understand the concept of generalization.

So far your tests are showing better results for new motors. Try to keep the same test conditions for both the sets e.g. Same batteries, same props, same height.....Did more tests this morning, with 2x 2400 mAh batteries (LiHV Hyperion G6 30/60C) attached.
Old motors/shell: 23:05
New motors/shell: 26:43
Again, hovering, so normal flight times will be better. Also, it was cold (-2 °C) and with a little wind. So not ideal, but good for comparison.
I made a spreadsheet - for those that want to add their tests, PM me or send an e-mail to the address mentioned.

Happy to see your contributions.
Fredz, interesting data, thanks for sharing. Have you compared top speed? Some here believe the new motors might not be as powerful, given the evidence from Healthy drone that the new motors pull less current. Not sure that evidence is relevant, but if compelled, a comparison for top speed would be another parameter of interest, if you and another person had a drag race next to each other.Did more tests this morning, with 2x 2400 mAh batteries (LiHV Hyperion G6 30/60C) attached.

Max speed isn't related to more powerful motors (except in a vertical climb and that's governed anyway).Fredz, interesting data, thanks for sharing. Have you compared top speed?

Good idea, vertical drag races would be another data point just to see what happens, although governed. The point being, if all datapoints show no difference, the new motors are a good option, even though those that have the old motor will never want to admit it . However, if the datapoints do show a difference, that would be interesting stuff.Max speed isn't related to more powerful motors (except in a vertical climb and that's governed anyway).
Your Phantom goes faster by tilting more and the degree of tilt is governed by the programming of the flight controller.
Did another test this morning with 2x 2800 mAh LiHV batteries (Hyperion G6), only with the new bird currently. Hovering result: 27:55. So a little more than the 2x 2400 ones (26:43). However, motors felt warm after this last flight, which wasn't the case with the 2400s. The 2400s weigh 203g each, while the 2800s weigh 258g each. I suppose the 2800s are really too heavy as a payload.
I wouldn't add anymore weight to the P3. It's already a pretty bloated little piglet.
I thought electric motors in general had a mostly flat torque curve, right from the go and up until a certain rpm when it drops (unlike combustion engines). The power of course changes and that affects efficiency in general, but power is a result of torque X rpm so if you accelerate it draws more current, so economy is about rpm not torque. Or so I believed.
