what a nice tool you put online!!! all thanks guy! :)
What could be nice is a warning signal for overgearing i.e...
I don't know if it's possible to do, but I would like to be prevented of thermalings or overgearings... i think the type of motor and the tires diameter should be enough to prevent this??? I realy don't know, just suggest...

And you could also add Feigao motors on your list...

You can be proud of your work BrianG!!!
