No such thing yet. Even with specifying gearing and such, there are simply too many variables to consider to be anywhere near accurate. The best you can do is estimate average current draw by your runtime and battery capacity figures, and then estimate burst current by multiplying the average current by 6-8.

On the next version of your ESCs, incorporate a mechanical fist that comes out and punches the user if they try to use such packs.

Is that why you haven't included this on your calc sheets?http://www.rc-monster.com/forum/show...motor+amp+draw

Just figures.....sometimes looking at all these electrical numbers gives that feeling of doom I had 20 years ago in my EE and EEET classes in college. If it weren't for HP calculators, I would never had made it through those classes.

Well, there are a couple reasons I didn't add that (yet):

- I forgot about it
- No feedback.

I still have my trusty old HP48gx, with a whopping 512k RAM card. lol.

no, they do it to hide the fact that they can't make power...

People need to start thinking about the power systems as just that "SYSTEMS". The ESC, Motor ,Battery & gearing are the system. The components of the SYSTEM are individual peices that need to be suitable for use with each other.

You would not go down to tire rack & get a set of subcompact car tires and expect them to work on a Boeing 747-400. Yes I know the 747 uses tires, but not ones ment for a corrola.

So yes, we all need to do the math.

LOL, I still have my HP38G calc. I recently took a chem class after 10 years of graduating college (now applying to med school). It was great, when I took a test, the calc checkers had no idea to look for stored notes in my HP. They were like whatever and gave it back to me. That calc had a great solver function. Sorry OT

Naaahhh. Just make a version with HUGE caps so that you get a giant spark...
