Motocalc etc
Hi depends -
I agree with you on MotoCalc as a predictor: it has its uses but I think it tends to produce figures which are better than one can obtain in the real world [as manufacturers do with their idealized or plain b.s. figures!]. In my various posts on motor performance ALL the figures quoted are mine, from my test set-up, not from Motocalc.
On second reading I understood your reference to "go with 7.2V" - initially I thought you meant batteries (i.e 6-cell) but I see you meant motor voltage [and, yes, I agree with you again].
Like everyone else, I've just been guessing on amp draw under flight conditions - I'm reassured to see that your prediction (2/3) is about what I had thought it might be.
Where does one get these Etec LiPolys? Am I to assume you feel they are better than Kokam?
Keep up the good work, Cheers, Phil.
