Thanks Jeff.
Just having trouble getting my wideband sensor working = properly.
What OAT were you working in.
I=E2=80=99m now going into 100+ would have been nice testing = in <70 OAT

Hi Steve, every installation is different; = however, I can post my numbers and methods.

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
