I'm not looking for any extreme high speed performance , but rather power my f-14 good and easy with 2kg thrust,
The L2855-2300 works great on 4s, the thrust is ~1.2Kg, the amps run ~40amps and the battery is able to hold voltage quite well so rpms are fairly stable.
just to ask, will the changesun run fine on my current freewing 70mm 3000kv?
or am i looking at a potential over heat issue?
The fan is a bit high for most 3000kv motors and there can be overheat problems from the high amp draw (~ +-90amps IIRC).
After looking at your picture I see the motor weight is 85 grams and it will reside in the motor tube so there will be less airflow over it to remove heat. If it had the offset It might last a little while but I think you would still damage that motor in this fan.
