G'day Pud
I fitted the third radiator back in 1996, when I was running in my engine a friend of mine told me that 80c was red line, he said the VDO water temp gage was a car temp gage, I was glad he told me that at that time because I had been running my engine for about 10 to 15 minutes at different throttle settings. I thought this is taking a long time to warm up and get into the green arc, the water temp was just getting to 80c when he told me 80c was red line, I droped the revs back to idle and shut down the engine and let it cool down, when I started flying my Thruster it was in the summer and the temp got up high all the time, thats why I put the third radiator on and its been good ever since. In the winter it would run to cool so I put a plastic cover over the third radiator to keep the temp up, it was a bit of pain if I went for fly on a warmish day the temp would get a bit high so I would have to land to take the cover off, So before I flew to Raglan flyin in June 2005 I made a ajustable flap to cover the radiator, and its been working great,
