about eCalc - drive calculator
Since 2004 eCalc provides web-based quality services to
simulate, calculate, evaluate and design
electric brushless motor drives for RC pilots of airplane, multi rotor, UAV, helicopter and EDF jets.
eCalc's
motor database is the most comprehensive on the web.
Follow us on Twitter @eCalc_e, Facebook Group eCalc or the eCalc YouTube Channel to get the latest news.
Is my Motor available?
Wondering your motor is in the Database? ...check the
full motor list. If you motor is missung just provide us
with the specifications...
You are a motor manufacurer?
Please send us
your specifications or fill in
this form and we will update our database with your motors.
Thereafter all visitors may use your motors for calculation. This
will increase your visibility on the market considerable.
Did you find a bug or data error?
please report to
info[at]ecalc.ch with detailed discription and screen shot - Thank you.
Missing your Language?
We are looking for
experienced RC Pilots willing to translate eCalc from english or
german to any other
language. Please contact us info[at]ecalc.ch.
