F16 w/68mm ducted fan, but which one?
I´m going to buy the "RCLander 70mm EDF F-16D Electric Ducted Fan AirFrame Kit w/ Retracts & Wheels", and I´m looking at which engine to choose. I´m thinking of either "68mm Aluminum Alloy Electric Ducted Fan w/ Brushless Motor(3575kv) #LEDF68-1A35"or the "68mm Aluminum Alloy Electric Ducted Fan w/ Brushless Motor(2185kv) #LEDF68-1A21".Do you have a recommendation

Basically it comes down to how you wish to power your plane.
There is no "best" or right choice.
High KV rated motors are good when you intend to use lower voltage batteries.
Lower KV rated motors are good for higher voltages.
High KV/Lower voltages require higher amperage draw from your packs to equal the performance of lower KV/higher voltages.
However the weight of the packs is also affected by either.
The 2185kv motor would be good for a 5-6S LiPo setup.
The 3575kv motor would be good for a 4-5S LiPo setup.
But you also have to factor in flight times, motor heating, wattage draw, etc. etc. etc.
