As you may know, I'm new to the brushless/LiPo world. I have jumped in head
first and am floundering around happily so far (and will be happier yet when
spring weather gets here to upstate NY).

I've been playing around with MotoCalc, plugging in the numbers for my RCer Warp 4 4T motor, TP 2100 LiPo, Phoenix 25 ESC, ElectroStreak airframe and various APC and Master Airscrew electric props.

I'm finding that when I run static tests with my Medusa Power Analyzer, I'm getting much higher amperage than the MotoCalc estimates. For example, using a TP 2S 2100mah 15C LiPo and an APC 8x6 electric prop, MotoCalc shows full throttle motor amps at a maximum of 20.7. In my static testing, I got up over 25 amps (over the 22amp recommended max. continuous for my motor) before I get to 100% throttle.

I understand that MotoCalc results are estimates, but I was hoping the figures would be closer than +/- 20%. Do I have unrealistic expectations? Maybe I'm doing something wrong in MotoCalc?

I have a 2S and a 3S 2100mah LiPo, and I've had to order props three times to find a pair that will work well with the two batteries.

Thanks for any insights, desmobob
