D-calc : Motor Drive Calculator for RC E-flight


Christian Persson is hoofdredacteur van de Duitse c't:
HMG - Presse-Service - Bilder & Vitae - Personen
Translations from c't magazine

Google "christian persson heise" , C't magazine is nooit bang geweest om een beerput open te trekken of een bedrijf aan de schandpaal te nagelen. Het heeft zelfs een bedrijf de kop gekost, die hadden geheugenboost software, bleek na tests totale humbug te zijn. Grappig, toen ik bij de Nederlandse versie van C't magazine kwam (F&L: F&L Publishing Group B.V.), bleek dat ik Christian Persson al 'kende' via de discussiegroep en fora. Kleine wereldje, die modelbouwers. Ik heb hem nooit onmoet.

Uit de Franse Electron Libre discussiegroep, de achtergronden van Helmut Schenk en Louis Fourdan (ontwikkelaar radarsystemen) ...
Guy Revel zei:
Une précision. Helmut Schenk, l'un des pionniers du vol électrique et solaire et ancien ingénieur chez Multiplex, est quelqau'un qu'on peut suivre les yeux fermés. Il a à la fois les capacités techniques et théoriques et l'expérience. C'est l'un de ceux qui s'y connaissent le plus dans le monde pour les propulsions et les hélices. J'étais une fois chez lui, c'est à la fois un paradis pour un modéliste et un paradis pour un matheux électonicien et informaticien. Incroyable !

Drive Calculator versie 3.4 is beschikbaar: D-calc : Motor Drive Calculator for RC E-flight

Christian Persson zei:
Manual

New in version 3.4
  • You may now toggle between 'Vopt' and 'Vpitch' display in the main window.
  • Search function "Find Weight ..." to search motors by their weight. This should make it easier to choose a similar motor (approx. same KV, same weight) for a performance estimation if your motor is not in the database.
  • For special purposes you may choose a 'virtual load' instead of a real propeller from the propeller popup menu.
  • After having run a database scan to find matching motors for the selected power supply and propeller you may select a small number of motors from the result by thrust. To do so, click in the area left to the 'thrust' bar next to the desired value.
  • Option to use the current motor as an auxiliary means for measuring the mechanical power draw of a propeller.
  • Shortcut option to select the motor or the propeller in the main window with a mouse click in the respective editing window. Click on the 'Type' label to select the propeller you are editing in the main window. To select the motor you are editing in the main window click on the label 'Name'.
  • Refined plausibility check on new motor measurement data. The check may now produce a warning message.
  • Several bug fixes.

Ik probeer de app te starten, krijg het scherm waar je de data kan invoeren, maar dat scherm "hangt". De cursor staat bij de optie om het voltage te wijzigen, maar laat het niet toe. alle andere velden zijn grijs en het programma laat zich niet meer sluiten. Alleen afsluiten van de iMac doet het programma verdwijnen. Onder Windows geen probleem. Op 2 Mac's met de allerlaatste Lion-versie gebeurt dit. Ik ga naar de door je genoemde sites.
Dank.

eCalc v6.5 beschikbaar
eCalc - the most reliable RC Calculators on the Web for electric Motors

Dear eCalc Community,

We will update eCalc today - this might lead to some disruption...

What's new:
Easy find your required motor with the new motor search function.

With this release we change the policy for using eCalc. For evaluation and for public use eCalc is available for free as demo version with reduced functionality and only 25% of the available components.
We introduce a small membership fee to get access to the full funcionality and all components of eCalc. You may become a eCalc member for a single calculator from $0.99 or for the entire bundle of calculators from $1.99.

Why a membership fee?
Over 10 years eCalc was free of charge and we tried to cover our costs by donations and advertisement. Unfortunatley this is not sufficient and we are forced to change our policy. We beleve having attractive price plans and remember: just one mispurchase of a component costs you much more than the eCalc memership fee....

Thank you for your understanding.

Markus
