EFFICIENCY

[Balwin]

When using a 6s battery and motor is the higher efficiency gained from using the smaller prop or larger prop? For instance with a 3s motor,battery combination the larger prop will be more efficient. What about 6s. Will the larger propeller always be more efficient?
Thanks

Larger propellers with low KV motors are generally more efficient, you may try playing around on ecalc to achieve best efficiency. http://www.ecalc.ch/xcoptercalc.php

Good tip, that helped a lot.

Hi Balwin also play with pitch range ie 10x4.5 or 10x4.7 I have 650 kv motors with 14x5.5 props have loads of lift , dont forget brushless motors are only 90% efficient
