What a joke. You build it put a brand name on it and the sheep will buy it..

IF your poping solder off your motor tabs ur not soldering your wires properly. Ever see a wire pop off an ESC?
ya, tell that to MR and Hara..Hara has to run wet cloth on the motor tabs...

maybe yoiur motor and/or batteries aren't good enough

I have seen many factory drivers unsolder wires when racing very low wind motors

Yes, heat = energy, thus ==> Remove heat = Remove energy.

Heat energy is wasted energy that doesn't make the car move. Making a particular part hotter or cooler can make it more efficient or less efficient, depending on the part. Cooling off a wire doesn't make anything more efficient...it might keep the wire from coming loose, but that's it.

That's the way I see it. Your making the same heat, but half of it is radiated to the atmosphere. So there is still a loss. But if it keeps your wires on, you continue to turn laps. They also look kind of cool too.

The anodizing is not conductive (just like on V2 enbells, etc). It will not short anything unless you manage to scuff the anodizing off.

-

The wire heat sink is meant to solve two problems:
1) helps dissipate the inefficient, excessive heat that can spread into the wires, which has been said to cause motors to run slower and an ESCs to run hotter
2) helps prevent motor wires from coming unsoldered

Agreed...it is not for everyone. If you have ever run a good, strong, low-wind mod with good batteries, you may understand why it can be needed. And yes, a cooling fan can help in a similar way.

Motors do sometimes come unsoldered. This is why the latest V2 endbells have holes for banana plugs.

yup, my car is definitely not fast enough...




i still think it's a waste of money. next people will be running heatsinks on their receivers.

why hasn't anyone made pre-heatsinked wires yet?

The heat doesn't come from -- or build up in -- the wires...it comes FROM the motor and to a lesser degree it comes FROM the ESC. If anything, the wires dissipate the heat from the motor, just not very well.

If the heat is coming from your wires, you need better wire...LOL...much better wire.

Poor choice of words...how does "spread into the wires" sound? I think you know what I meant , but I edited my previous post for clarity.

Heat lost in the wire is heat that is of no use to powering the motor, correct. The vast majority of energy going from the battery will be lost as heat. If you can keep a part cool enough to lose less heat, it technically should use the energy on the motor, however, thats not always what happens.

It doesn't save any energy or put any less or more heat/energy into the motor. The heat/energy wasted is the same, it just gets dissipated by a different part. It's dissipated through the heatsink, rather than the wire.

Actually excessive heat would produce higher resistants in wires.

Well thats what they taught me in school..

It's probably also going to go faster when there's a high tide because the Moon is exerting more gravitational pull, which would make the car "lighter".

In the real world, a 50* change in a small portion of the wire (it won't be that hot all along the wire, only close to the motor)...very high quality stranded wire...isn't gonna change anything.
