You can ALMOST work out the power by the V and A listed... but those sets of numbers only list Vm which means volts minimum seen. I would guesstimate the volts to use are a bit higher... so make up something a bit higher. LOL.
Multiply out the VxA and the second set are wrong.
That V and A look correct, but the Watts should be 500W or so area. Not 800W area. Note it is Wp listed which means the PEAK ever seen on that run.... but 800+ would still be asking a bit much, or would last only for the very initial 1.0 secs!! LOL
Both would not give 1.3Kg thrust.... the top could. The lower set would prob be 1.0Kg area, or a bit under.

I would not use the 2100kv, unless it is a LIGHT plane!
Your maths look fine, so 2.5mins at WOT...... maybe 3.0mins with care.
