Watts question

[jkr]

Yes on six but i mention 8s.

[srislash]

I would tune the run time by prop. The 5500 watt will turn a larger prop or the same prop easier.

[ReddyWatts]

If the effeciency rating is the same on both motors, it means you will be able to run a little bigger prop on the higher wattage motor.

[LOVE6S]

Back to the original question, sounds like you may get more run time on a higher watted motor

[ReddyWatts]

Run time should be the same. More mass in the higher wattage motor will dissipate more heat. (watts)

[LOVE6S]

Ok thank you.

[lavacaboater]

Do think a 5500 watt motor will eat up the batts faster than the 4500?

Yes. P=IE where P is power (watts), I=current and E=volts. If E (battery volts) remains constant then as watts goes up so will current (amps). Hope this answers your question.

Will a 5682/5692 even fit in a fantasm? I run a 5682 (740kv) on 10s and spin an x457 in my mono and it's WAY bigger than the 4082 in my genesis, I would check what will fit first of all and would also think about how it will handle especially if your planning on running a large prop as torque roll will be an issue along with the extra weight up top.

Not trying to discourage you but I very nearly went down the same route but was advised to avoid for the same reasons I've listed above and having built a mono instead with the same motor can fully understand the reasons why

[LOVE6S]

It will fit,I am gona give it a try, let you know how it comes out.

The answer for the original question is YES, you will get less running time, I used both Neu 1527 1500kv and Neu 2250 1400kv for my Q hydro, same prop, I got less running time with 2250 even lower kv than 1527 but lower temp on motor and higher temp on lipo and esc, the best setup is a perfect matched setup

Thank you,I think if I was going to have one of the 3 have a higher temp, it would be the motor, would you agree?

[kevinlew211]

Yup, motor can handle more temp without burning more than the other 2, and if you even willing to slowing down a bit then everything is cool even motor, to me, I rather lost 5-6mph by proping down, less kv or even lower voltage for reliability.
