Default Phoenix Preceptor 90mm

Anyone still flying these? I just put one together and am pretty impressed with it! Pretty jet with a nice presence at the field amongst all the foamies

Went with an 8s Jetfan 90 V3 setup

Note that a motor does not behave like a simple resistor, in that current drawn is not proportional to voltage but proportional to voltage≤ Name:  eek.gif

It is a far from a linear effect, resulting in higher current than one would expect.
In your case, going from 10 to 12s, current wants to increase by factor (12/10)≤ = 1.4, 40% more.

Power drawn is proportional to voltage≥ Name:  eek.gif

A massive effect.
Power would want to increase by factor (12/10)≥= 1.7, 70% more.

Some silly, expensive and hopefully instructive examples
