No problem. It only adds about an ounce...They tell the weight of all the components...

It's too small to work properly IMO.

Do you mean like the amount of heat energy it can take away?

Well if that pump has a decent amount of flow rate, then it would work very well.

I'd like to see an tube water jacket though, to go around the motor. boats have jackets, but they are just coils which have crappy heat transfer.

I think computer CPU water cooling guys should be helping out there.

I just thought of it, does anyone here know what a heatpipe is? That would be nice to have a heatsink using heatpipes for a motor.

Run a more efficient setup and you don't need fans on the motor to start with. (neu) the speedo might need a fan, but with a fan the problem is solved allready. Which weights less than a fluid cooled system.

With 'too small' i meant the radiator. You might need a fan on the radiator to do its job, and with that, you are just transporting heat. (which is the basic of a liquid cooled system, transport heat to a larger area/different place )

Yah right, kinda defeats the purpose huh. The amount of money you spend on the thing, you could have bought a more efficient motor...

With all the advances in semi-conductors these days, we are fast approaching room-temp super conductive materials. that will be the day :027: :017:

I find the humor of the radiator on the various water cooled rc vehicle that I have seen. The chassis on most converted vehicles is al, which is an excellent conductor of heat. Why not use some thermal epoxy and glue an al tube around the edge, or in an unused area. Use about 12" and a small pump that would slowly move the water around. It would not weigh much. No need for a radiator and fan IMO. You may be able to get away without using a pump, possibly some glycerol? and hope that it would thermo siphon.

Fine designs' setup is my favorite. Add a water jacket, extra battery, lines, pump, raditor with fan, etc. Why not use a lower kv motor and put the money toward 6s lipo? That would run cooler, even with a feigao motor. Like a 10xl? Put some clip on heatsinks on the motor too, everything helps. I would like to try a hydra controller, but it only handles 6s, so a quark air esc can do that.

I'm still thinking about getting one of the TCS setups. I think it would work decent, but I guess the only way to find out is try it. The main advantage I see is a cooler running system, if only slightly, which could allow you to have a wider array of gearing choices. Maybe use something like the 9920 marine and make use of the tubes that run through it...I'll probably try one on my BPP LSP. I just might help with heat, since it gets pretty damn hot in the summer around here...

I am completly sold on HV setups and will only run HV from now on.

I am running 8S A123's and the CC HV110, with the pistix Serum referenced earlier, and I don't even break 100F in racing conditions.
I run this setup on my 8ight, G2R, and MBX5T.

My only issue is throttle control with the HV110 but I am getting a better handle on this over time.

My hope is that the MMM will handle 8S A123's. That is... if the MMM is ever released

Agreed. I like HV as well, only issue that I have, that you probably don't have, is it gets well above 100 degrees frequently around here. I hope if I try the water cooling, it will let me keep it nice and cool in the summer.

What is the throttle control like starscream? I have a hv 85 and plan on using it in my aftershock on 10s.

@squee
Ya, It doesn't normally get above 90F in Seattle.

@linc
By default, the HV's throttle seems to be all or nothing. I have been tweeking the settings and playing with the throttle expo to get the most comfortable feel. Its getting there.

I also noticed that the esc cutsoff everynow and then when I punch it to clear a triple. This may simply be my cutoff kicking in. I may just dial the lvc settings to 1V per cell to test the A123's.
