What happens to your water = temps? Is it just your oil thats the problem?

I had a TC & AP = inspection in Sept. lots of little issues to fix with the airframe which = I'd neglected, due to being so immersed in the powerplant. most bits = done now so will be back into engine runs again soon.

Hi Guys
For those who have tested and flying their machines.
I=E2=80=99m finally about to ground(stationary) test our Renesis 4 port = powered Glassier Super IIRG
EC2, EM3, RD1-C Electrical Pitch Prop.

Your wisdom, experiences, testing procedures to carry out would be very = much appreciated.

Particularly whats reasonable to expect from my cooling system (modelled = of Tracy=E2=80=99s RV8)?
Now I=E2=80=99m sure it depends upon load and OAT, but what where your = experiences?
How long could you guys run before overheating etc?
Did you provide any supplemental cooling to extend this testing?
I=E2=80=99m thinking of putting a water mist jet into the cooling duct/s = to see if it significantly increases cooling and time testing.

Appreciate you feedback.

Sincerely

Steve Izett
