Don't blow into you radiator.  The high = force wind could damage it.  Also, the cardboard seal was important = to make sure it was pulling air through the radiator, and not just from = the ambient air near the exit.

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
