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 )

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.
