Derek, you have a PM. If you want to gloat some more, use that instead.

i was running one in my car, the rx pack plugs directly into the speedo because the speedo has the regulator built in.
kenny l - it is not that we were unwilling to do so. the fact of the matter is that without the rx pack plugged into the speedo, the spedo would not work. much the same way that your tekin will not work without the switch on. had we wired the rx pack directly to the receiver, the srevo would run on 7.4 v. and still,by the way, send 7.4volts back to the speedo. we went over this in tech with the tech team and they came to the same conclusion. for the record, when i first put mine into my car, i tried to run without an rx pack just a booster, and the speedo would not function. even if the rx pack would run throug a regulator, then to the reciever, then to the speedo, you would still be sending more than 3.7v to the speedo, just like everyone else.

Were they really that much faster? I mean look at how skinny those motor wires are...

It didn't need to be on when the power from it is coming from the other side. EVERY Brushless system is still "ON" without the switch saying "ON" ...it won't work but power is available.

Also, I remember resistance and wire gauges as the bigger the wire,
the less resistance it has. The only way I remember this is to think of the current flowing through the wire in terms of water flowing in a pipe. Smaller pipes have more resistance to water flow, just like smaller wires have more electrical resistance.

veecee - the thing is top fuel.
derek - you are wrong. we tried it to avoid the controversy. sorry if you were not there to see it.

We're dealing with low voltage. Think of a giant building size block of copper...if you connect 3.8 volts to it that doesn't mean it's more efficient. In the grand scheme of what we are dealing with the heavier wire offers NO advantage to run. So I am wrong in the terms of "less resistance" and should have used wasted energy.

This is why I'm watching this thread.

Water is a bad example...that doesn't take into account flow rate. You can have more water coming out of a smaller pipe since the water being used depends on what's on both ends.
A giant pipe will have a slower velocity of water. A rocket uses this to get the thrust faster...your car exhaust does similar. Exhaust gas velocity is no 100% dependent of pipe size.

yes, and to be more specific frequency also makes a difference. I'm not sure where we fall on brushless but since we've run ESCs at higher frequency voltage I'll be it also follow AC wire physics and only really flows on the outside skin of the wire...making thickness not as important.
