'average' and 'burst' and 'max', so to the user wont be in doubt where to put some number. liek a motor come with 2-3 specs. or say, some lehner motor, like a 1940/7. is that 1940kv..7 pole..no. Bad example. cant explain it better tho..my bad english...
First of all, what is "fx"? Is that like "ie", "eg", or "example"? I guess I could maybe offer some very basic guidelines as to what current numbers to use. 12,000A is not very realistic unless you have a 500Ah 24C battery.

Like I said, it was something that someone requested. It's a good starting point for a very safe gearing for someone with no experience with how BL setups act. From various test calculations on different setups, it tends to be very conservative for gearing. Of course, top speed would suffer, but the chances of pushing the components too hard are pretty slim if you follow that rule.

Like I said, it was just to give newbies a basic idea of how things work. Since it doesn't have absolute numbers, it just shows relative changes. Definitely not definitive (lol, that was a conflicting statement ).

lol, now I see! Yeah, that would be bad. I had to really look to see what you meant. I think for the sake of simplicity, I would add some kind of note or indicator showing which balance plug goes with which main harness wire.

To be honest, I just don't feel like creating graphics for every combination. I can just imagine if I add E-Flite connectors, someone will say "where are the traxxas plugs", or "where are the bullet plugs". I think people are smart enough to realize they can use whatever connector that floats their boat.

The import feature would be the easiest way to implement this I think. The current export feature is "blind"; meaning, it simply looks through the page and gets the field title and value for any field with a custom element attribute. I'd have to design the import/export system such that it is backward compatible with any future upgrades (like if I add a new field, or remove one). I'll have to give it a little thought.

This was actually requested a while back. But due to complexity, I compromised by creating a table with alternate pinions which show the resulting speeds (click the little gears icon in the results section - in the top speed estimator only).
