Programming an ESC
« on: August 26, 2018, 21:36:15 PM »
Browsing models and things on the web I came across an ESC "programming card". This got my interest and it led to an article that stated "Because brushless motors are electronic, they require programming that matches them to a given battery pack and vehicle."
https://ourpastimes.com/program-esc-brushless-motor-7891482.html

A question immediately came to mind, should one always programme and ESC in a new application? Never done it before and not aware of any problems.

Thoughts please..............

The vast majority of modern ESC come with their parameters pre-set such that will work well with most setups.  Unless you're after that last percent of performance most times it's just fit and forget.

The one exception would be for planes that have folding props.  These need the brake option being set to "on".  The factory set default on most ESC is "off".

Bottom line.  Just go out and fly!

Most ESC's will work OK out of the box for fixed wing applications. An exception I have found are the YEP ESC's from HobbyKing which come in heli mode. You definitely need the programming card for the YEP ESC's

As I've just discovered having bought 80A and a 100A units for planes, only to read that they come with things like default soft-start and governor modes.  At least the programming card is only a fiver even with p&p.  The other pain in the bum escs are E-Flite, they seem to be hard coded for Spektrum throttle range so when used with FrSky nothing happens with low and high 10 % throttle movement.
flying's easy - it's getting it back down in one piece that's the hard part

You should be able to "fix" that by adjusting the throttle travel in the Tx.

Yes, it's easy enough to set limits on the throttle output.  I just found it surprising that the esc couldn't be taught new limits.

Never had an ESC that couldn't be taught new throttle limits - that's the firsts thing I do with an ESC.
Must make sure I avoid E-Flite.

There are some problems with certain radios, You have to reverse the throttle on Futaba radios and some radios
( Hitec ) need to have their end points set to 120% or even 140% either way,,

That doesnt sound quite right Paul, you're saying that your HItec needs 140% travel to achieve 'Spektrum travel' which itself is 80% of the standard?  So your Hitec is nominally giving 57% of 'standard' channel timing?   
I've a few Hitecs and mine are close to standard timing, like Futaba etc  $%&
Cheers

 No I am not saying that, I don't have a hitec radio, only Futaba  :co but I used to have a model shop and these were the problems that I encountered and had to solve for customers, I never sold Spectrum radios,,  :-X
