I took my Rio out for the first time yesterday and ran it till it could not plane anymore. The motor was very hot post run and was wondering if that is normal? Could a coil or jacket be installed?

I was looking at the cooling hardware more in depth and noticed that the cooling tube that is zip tied to the motor is very loose and barely touches the plate. Even if it were tight only a sliver of the tube makes contact anyway because the tube is round, so cooling is not that good right off the bat. I am going to use stainless .020 safety wire to attach the tube and spread a lot of thermal heat sink compound to see if that helps. If that doesnt work too good then I will try to weld the tube to the plate. Anyone else modify their cooling system?????? Will try to post pic this weekend.
