Speed Calculator

lol, yeah, it does delve a little on the programming, but there are some here who have good ideas so I like to keep such discussions open. Yes, additions of motor/diff/tire/transmission/spur gear data are always welcome. You can either post that info here, or send it to the email address listed in the FAQ page of my site.

I sent you a PM, but in short, I spoke to Dave from progressiverc and he wants to do something, just not sure what yet.

Mimicing a load on a setup can be good if the user knows what they are doing, or the results could be completely off base if they enter in garbage. As in any programming: garbage in=garbage out. It's not like aircraft where the prop places a fairly constant load on the system; with cars, it's MUCH more peaky. But, a couple pages do make an attempt at implicitly taking load into consideration:

• http://scriptasylum.com/rc_speed/_speed_amp.html - Takes drag and vehicle parameters into consideration to estimate power needs.
• http://scriptasylum.com/rc_speed/_car_setup.html - Allows you to enter motor resistance and arbitrary current draw to estimate adjusted kv, torque, and power.
• http://scriptasylum.com/rc_speed/_power.html - Gives an inkling of power needs by estimating amp draw given runtime and battery capacity.

I suppose you could suggest a new background skin. Not sure if it will be implemented, but I will consider it. I try to keep image use to a minimum to speed it up, plus it's more utilitarian, so design takes the back burner.
