Thanks Andrew
What happens to your water temps? Is it j= ust your oil thats the problem?

I had a TC & AP inspection in Sept. lots of little issu= es to fix with the airframe which I'd neglected, due to being so immers= ed in the powerplant. most bits done now so will be back into engine runs a= gain 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 pow= ered Glassier Super IIRG
EC2, EM3, RD1-C Electrical Pitch Prop.

Your wisdom, experiences, testing procedures to carry out would be very muc= h 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 expe= riences?
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
